Device Dashboard

Description

The Device Dashboard is where users of any permissions level can view detailed information specific to an individual device. Every managed device in OmniCenter gets its own Device Dashboard.

The Device Dashboard of a Windows device experiencing a performance threshold WARNING state for disk utilization.

Clicking on the name of a device almost anywhere in OmniCenter typically takes you directly to its Device Dashboard. Alternatively, you can search for the name of the desired device using the search icon on the main menu, and then click its name in the results.

The Device Dashboard is made up of several tabs, with each tab focused on specific aspects of the device. The tabs and their contents are detailed below. If the device is currently experiencing any problems, the relevant tab where the problem can be viewed will be highlighted in the color of the most severe alarm state.

To the left of the tabs is the device breadcrumb display. This contains the device name, the device type, the currently polled IP address for the device, and the category and site the device belongs to (both of these last items are clickable links which open the dashboard for each respective device group). To the right of the tabs are the device menus.

The Device Dashboard header, showing the device name and type, IP address, category and site. The category and site are links that open their respective dashboards.
Device or Devices dashboard

Don’t confuse the Device Dashboard with the “Devices” dashboard. These two dashboards provide very different functionality. The Devices dashboard provides information on the overall health of device groups, while the Device Dashboard provides detailed information specific to an individual device.

The Device Menus

The device menus are a set of pull-down menus in the top right of the Device Dashboard header. These menus are contextual and display or change their contents depending on the device type and the permission level of the user.

The “device menus” on the right side of the Device Dashboard header. Administrators can click the gear icon to switch to the device administration dashboard.

The Reports menu provides quick access to a number of useful device-level reports and tools that can help troubleshoot a variety of problems.

The Grouping menu provides links to the Strategic Group Dashboard of each strategic group that the respective device is a member of, as well as links to the Device Dashboards of the parents and children of the currently viewed device.

Overview Tab

Device Icon and Status

A virtual device displaying virtualization information.

In the top left of the Overview tab is shown the icon representing devices of this type. These icons are how host device types are represented on the topology maps (see Topology Tab below).

Below this are four indicators representing the current number of OmniCenter checks assigned to this device that are in the CRITICAL, WARNING, ACKNOWLEDGED and HEALTHY states. If any of these indicators have no checks in that state, they will show a faded 0.

If the device is a virtual resource, information about its host, cluster and hypervisor will appear below the status indicators. These are clickable links that will navigate to the item’s respective dashboard.

Host Information Panel

Below the status indicators is the Host Information panel (collapsed, click to expand), which contains the following information:

The Host Information panel.
  • Current State
    Displays an indicator showing the current reachability state of the host (up or down). Click Status Details to the right of the indicator to open the Status Details dialog for the device.

    The Status Details pop-up.
  • Last Reboot Time
    The operating duration since the last time the device successfully booted. If the device has been continuously operating for a very long period of time, and what’s reported here seems wrong, it may be that the counter in the device has reached its maximum value and has rolled-over to zero again, like the odometer in a car. Refer to the device manufacturer for more information.
  • Type of Device
    The name of the device type assigned to this device.
  • Category
    The category this device belongs to. Click to open the Category Dashboard for that category.
  • Site
    The site this device belongs to. Click to open the Site Dashboard for that site.
  • Address
    Displays the physical address location configured for the site to which this device belongs.
  • Business Workflow(s)
    Displays the strategic groups that this device belongs to. Click a strategic group name to open its dashboard. For users with the SuperAdmin permissions level, an edit link next to each strategic group opens the edit page for that group.
  • Uptime
    Shows the uptime of the host (as a percentage) for the following time frames:

    • Previous Month – From the first day to the last day of the previous calendar month.
    • Month to Date – From the first day of the current month to the present day.
    • 7d – The previous seven days.
    • 1d – The past 24-hours.
  • Serial Number
    The serial number of the device.
  • Description
    The manufacturer’s device description.
  • Device Information
    Various collected information about the device, such as device serial number and software version. If Log appears on the right of the title bar, it means that OmniCenter has detected and logged changes to the hardware. Click the button to open a pop-up display showing the hardware change log.

See How to See Hardware Changes for a Managed Device.

Host Current Issues Panel

Below the Host Information panel is the Host Current Issues panel. This panel displays any incidents currently affecting this device, sorted by duration (how long it has existed) from shortest to longest. It provides the following three pieces of information:

The Host Current Issues panel.
  • Type
    The nature of the respective incident. Threshold check incidents are clickable, and open an Exceeded Thresholds page. Click the icon to the left of an incident type open the Incident View dashboard for that problem.
  • Description
    The description (name) of the specific check responsible for that incident.
  • Duration
    The total length of time for which this incident has existed (whether acknowledged, or not). The list is always sorted by duration from shortest (at the top) to longest.

Statistics Info Area

The rest of the Overview tab displays a collection of what is generally considered to be the most immediately useful information about that device type. This information is selected from the other tabs for display here so that you don’t need to dig through them to find it. (However, any information being displayed here can still also be found on the relevant tab of the dashboard.)

If the device is a router or a switch, and the interface zoom feature has been activated for any of that device’s interfaces, graphs for those interfaces will be shown at the top of the display.

For statistics displayed in this area that have had a threshold check configured for them, the background of the statistic display will reflect the current state of its threshold check. Additionally, a small star/asterisk icon will appear to the left of the statistic value. This icon will reflect the current state of its anomaly check, if one is configured. If no anomaly check is configured for this statistic, the icon will appear gray. If no threshold check is configured for this statistic at all, the background will simply appear white (see image below). Note that statistics are recorded and displayed for each device regardless of whether a threshold or anomaly check is configured for them.

All configured threshold and anomaly checks are in an OK state (green). A gray icon indicates no anomaly check is configured, and a white background indicates that no threshold check has been configured at all.

Services Tab

The Services tab provides current status and history on all service checks added to this device. It contains two sections, the Services List panel and the Services State History panel.

Services List Panel

This panel shows all of the service checks currently assigned to this device. (It is not a list of services currently running on this device.)

In the top right corner is a tactical overview-style status indicator displaying the number of service checks currently in each state on this device.

Below that is the service check list. Each entry shows the name of a service check assigned to this device, its current state, its most recent output to the history log and the length of time the check has been in that state. If the state shown is CRITICAL, a link icon appears on the far right of the listing. Click this icon to open the associated incident in its Incident View dashboard. Click the down arrow on the right side of the listing to expand the entry and display the state history log for that service check. Click the check name itself to see a modal dialog displaying a variety of detailed information about the service check itself.

The Services List panel showing all service checks currently running on this device and their current state.

Services State History Panel

Below the Services List panel is the Services State History panel. This log shows an aggregate history of all service check state changes for this device.

The Services State History panel displays an aggregate history of state change events for all service checks added to the device.
  • Description
    The service check on this device that changed state.
  • Time
    The timestamp the state change occurred.
  • State
    The state resulting from the state change.
  • State Type
    Indicates whether the check was in a period of rechecking to confirm the state (SOFT) or had generated an alarm (HARD)—for CRITICAL states only.
  • Incident ID
    Provides a clickable link to the incident opened as a result of an alarm. Clicking the link opens the Incident View dashboard for the incident.
  • Output
    The output of the completed check. This output goes into the history log for this device. This is also the text that will appear in an alert notification that includes the {OUTPUT} macro.

Enter terms into the search boxes at the tops of each column and press the Enter key to filter the table. Delete the terms and press the Enter key again to restore the list.

Performance Tab

The Performance tab is where all performance statistics are displayed, including those from threshold checks and database monitoring.

The navigation panel on the left provides quick access to the list of collected statistics on the right. Clicking on an entry in the navigation list will zoom to that entry on the right and expand its display.

All statistics feature a mini histogram on the left side showing their performance over the last 24 hours, with the peak measurement for that time indicated above the graph. To the right of the histogram are three cards displaying the current, average and maximum values for that time period. At the far right of the statistic is a graph icon which opens the statistic in a full-page histogram that provides complete filtering options.

Displays on the right will stay expanded until closed or the page is navigated away from. Entries are color-coded according to their state in both the navigation list and the display list.

Topology Tab

The Topology tab displays a visual representation of the immediate layer 3 parent/child relationships of this device.

Placing the mouse cursor over any of the device icons will display the status of that device. Clicking an icon takes you to the Topology tab of the device dashboard for the clicked-on device, allowing you to follow a network path. Click Back to retrace your steps backwards as you click forward through the network hierarchy. Buttons at the top left of the map allow you to zoom in/out.

The left side of the tab displays the same information as the left side of the Overview tab (above).

QoS Tab

The QoS tab displays Quality of Service data for the particular device. The tab contains four panels, outlined below.

Outbound Panel

The Outbound panel shows data for outbound peak bandwidth and dropped bits for each interface of the device.

Click an interface name to navigate to a report for that interface that includes graphs for bandwidth, errors, post-policy bits, dropped bits, queuing discards, current queue depth and traffic flow through the interface. This report will only show graphs for one output policy at a time. Use the filtering options in the report to change the report time frame and select which output policy to view (see Fig.1 below).

Inbound Panel

The Inbound panel shows data for inbound peak bandwidth and dropped bits for each interface of the device.

Click an interface name to navigate to a report for that interface that includes graphs for bandwidth, errors, post-policy bits, dropped bits, queuing discards, current queue depth and traffic flow through the interface. This report will only show graphs for one output policy at a time. Use the filtering options in the report to change the report time frame and select which output policy to view (see Fig.1 below).

Fig. 1. QoS interface report filtering options. Note the OUTPUT POLICIES section on the right. If there were more than one policy, you would select it using the available radio buttons.

QoS: [Interface] Graph

This graph shows post-policy bits for the interface named in the panel header.

The reference time at the top of the graph indicates when the graph was last updated.

The graph can be printed or exported to various image types using the small button at the top right of the panel.

This panel will always show the interface whose traffic is distributed across the largest number of traffic classifications configured on the device. (This is not necessarily the interface with the largest traffic volume.)

QoS: [Interface] Dropped Bits Graph

This graph shows dropped bits for the interface named in the panel header.

The reference time at the top of the graph indicates when the graph was last updated.

The graph can be printed or exported to various image types using the small button at the top right of the panel.

Below the graph is a table displaying the traffic classifications configured on the device. For each classification, max, average and current bits per second values are shown for post-policy and dropped bits.

This panel will always show the interface whose traffic is distributed across the largest number of traffic classifications configured on the device. (This is not necessarily the interface with the largest traffic volume.)

The Trends tab shows “time in state” data for the device.

Histograms near the top show aggregate “time in state” values for the previous 12 months, while the Alert Details panel shows recent alert conditions for the past 24 hours, 7 days and 30 days.

Click Report Options at the top to change the time frame from which the data is generated. If you have added custom times to the standard OmniCenter time frames they will be available as well.

Administration View

The administration view of the device dashboard allows a user with Admin or SuperAdmin permissions to configure various OmniCenter-specific settings for a particular managed device.

To open the administration view, navigate to the device dashboard of the managed device you wish to configure. Click the gear icon to the right of the dashboard tabs to switch to the device administration view. The gear icon will then become a dashboard icon. Click the dashboard icon to return to the Device Dashboard.

Most of the settings in the administration view are automatically configured by OmniCenter (using autoconfiguration rules and device templates) when the device is first added, and generally should not be configured manually. Manual configuration should only be done when configuration using automated means is not possible or practical.

Click the gear icon to switch between the Device Dashboard and the administration dashboard for a device.

Autoconfiguration rules are typically run only once, when a device is first added to OmniCenter. Device templates, however, apply their settings to devices every time a discovery poll is performed. Understanding which settings are controlled by device templates is important, as those setting will be overwritten—undoing any manual configuration.

Settings that are automatically configured by device templates are indicated with a lock icon next to the setting or in the setting’s Actions column, preventing users from making any changes. Click the lock icon to unlock the setting and display an edit icon alongside it. Then click the edit icon to open the edit page of the device template currently controlling that particular setting and make the change there instead. Change the setting as desired and save the template.

The administration view is organized into the following tabs for easy navigation:

  • Main
    Settings to control high-level and general aspects of device management, as well as authentication.
  • Host
    Settings to control alerting options and parent/child device relationships.
  • Service
    Settings to control of monitoring of running services.
  • Instances
    Settings to control interface monitoring, the collection of statistics from the device, and the configuration of threshold checks.
  • Documentation
    Additional user-generated information about the specific device.
Navigate the administration view using these tabs.

Main Tab

The Main tab is made up of 3 sections:

  • The polling and alerting status indicators
  • The Details section
  • The Authentication section

You must click Apply Changes at the bottom of the page for any changes you make here to take effect.

Polling and Alerting Status Indicators

The top of the page contains the polling and alerting status indicators, and show whether or not device polling, threshold check alerts and host and service check alerts are active for the device.

The polling and alerting indicators.
  • Poll Device
    This indicator/switch shows whether or not the device is being polled by OmniCenter. Click the switch to disable polling for the device.
  • Threshold Alerts
    This indicator shows whether or not any threshold checks are configured and active for this device.
  • Host & Service Monitoring
    This indicator/switch shows whether or not critical states for host availability checks and service checks will generate alarms for this device. Click the switch to disable monitoring of host and service checks.

You must click Apply Changes at the bottom of the page for any changes you make here to take effect.

Details Section

The Details section manages the following core settings for the device.

The basic Details section.
  • Name
    The name assigned to identify this device. OmniCenter will use this name in all dashboards that list this device.
  • IP Address
    The IP address assigned to this device on the network. Enter a new IP address to change it. Click the edit icon on the left to manage alternate IP addresses for this device.
  • Category
    The category device group this device has been assigned to. If the category has a device template assigned to it, the settings from that template will affect this device. Click the drop-down to select a different category for this device.
  • Strategic Group(s)
    The strategic device group(s) this device has been assigned to. If the strategic group has a device template assigned to it, the settings in that template will affect this device. Change, add, or remove strategic group associations by clicking the edit icon. A device may belong to multiple strategic groups.
  • Site
    The site device group this device has been assigned to. If the site has a device template assigned to it, the settings in that template will affect this device. Click the drop-down to select a different site for this device.

You must click Apply Changes at the bottom of the page for any changes you make here to take effect.

Debugging Tools Menu
At the top right of the Details section is the Debugging Tools menu, which provides the following contextual debugging tools for devices:

  • Run Discovery Poll – Schedules an immediate discovery poll for the device.
  • Test SNMP – Make sure SNMP is working properly with this device.
  • Test WMI – Make sure WMI is working properly with this device.
  • Test Call Manager – Make sure Cisco Call Manager is working properly with this device.
  • Complete Debug Polling – Make sure OmniCenter is communicating properly with this device for polling purposes.

These tools will not appear for devices being polled by a service engine, as OmniCenter does not usually have direct access to these devices.

Details Section – Advanced

Click Show Advanced Options at the bottom of the Details section to expand the section and display the following additional settings.

The advanced options of the Details section.
  • Device Tag(s)
    Device tags allow you to apply custom tags to devices. These tags can then be searched for using the OmniCenter search engine.
  • Use Templates
    When set to OFF, this device will not accept settings from any device templates except the “device-level” template, which must be manually assigned to the device (see below). Turn this setting OFF to assign a device-level device template to this device.
  • Template(s)
    This table displays the device templates that this device is currently receiving configuration settings from and at what hierarchy levels they are being applied (templates lower in the table overwrite settings from templates higher in the table). At the bottom is the “device-level” template, which must be manually assigned to the device by clicking the edit icon on the right and selecting the desired device template from the drop-down. The Use Templates setting (above) must be set to OFF to assign a device-level template.
  • Device/Subtype
    Displays the device type and any optional subtypes assigned to this device. The assigned type and subtypes can be changed by clicking the edit icon to the left. Only one device type may be assigned per device. However, multiple subtypes may be assigned. Note: Each assigned subtype may apply its own device template settings to the device.
  • Remote Poller
    Use this drop-down selector to select the service engine that should be used to poll this device, if any are being used.
  • Validated
    When set to OFF, this device will not appear (or contribute) to any generated reports or appear in dashboards (except administration dashboards).
  • Disable Deletion
    When set to ON, this device cannot be deleted from OmniCenter. This setting is ON by default to prevent accidental device deletion. When set to OFF and Apply Changes at the bottom of the page is clicked, Delete Device will appear next to Apply Changes. Clicking Delete Device will permanently remove the device and its entire collected history from OmniCenter. It is typically preferable to disable a device in OmniCenter to stop monitoring it, rather than deleting it entirely. (The mass device deletion capability of a SuperAdmin is not restricted by this setting.)
  • Scheduled Config Checks
    When set to ON, OmniCenter’s config manager will perform its regularly scheduled device configuration archiving and check for this device. Set to OFF to exclude this device from configuration management.
  • Auto-Configuration
    This setting controls when autoconfiguration rules should be run on the device after the device has been initially discovered. The available settings are:

    • Never – Autoconfiguration rules will no longer be run on this device. Select this after using one of the other options.
    • Run Once – Autoconfiguration rules will be run and applied on the next scheduled discovery poll of this device. The field will then reset to Never.
    • Run Every Repoll – Autoconfiguration rules will be run and applied on every discovery poll of this device.
  • Shell Type
    This setting selects the method by which OmniCenter will communicate to this device through the command line. The options are:

    • System Default – Use whatever communication method is set as the system default.
    • SSH – Force OmniCenter to communicate with this device using SSH (if the system default has been changed).
    • Telnet – Force OmniCenter to communicate with this device using Telnet.
  • Polling Type
    (Windows devices only) This setting is used to override the method by which OmniCenter polls Windows-based devices. The options are:

    • System Default – Use the method set as the default for all Windows devices on the System Preferences page.
    • Force WMI – Override the default setting to use WMI as the polling method.
    • Force WinRM (PowerShell) – Override the default setting to use PowerShell via WinRM as the polling method.
  • SNMP Options
    These settings control how SNMP queries are made to this device. All settings are optional. The settings are:

    • Timeout – The initial timeout (in seconds) for SNMP queries. Default setting is 2, maximum is 60.
    • Retries – The number of times a timed-out SNMP request will be retried. Default setting is 5, maximum is 20.
    • Alternate SNMP Port – Specify an alternate port to be used here.
    • Bandwidth Override – Specify a custom bandwidth speed to override the detected speed for all interfaces on this device. Delete the setting to return to the device default speed. (This setting always overrides any individual bandwidth override settings configured on the Instances tab.)

You must click Apply Changes at the bottom of the page for any changes you make here to take effect.

Authentication Section

This section manages the authentication settings for this device. The range of settings available is determined by device type. It is highly recommended that these settings be controlled through the use of device templates.

When configuring manually: For network devices, enter only a username if you are prompted for one to log into the device. If you use a username that is pre-enabled (logs in at the highest level of device access without further authentication), leave the Enable Password field blank.

Fields that are controlled by device templates are indicated by a lock icon to the right of the field. Click the lock to allow editing of the controlling template.

The Authentication section of the Main tab. Note that all but two settings on this particular device are controlled by device templates, as indicated by the lock icons.

OmniCenter does not support the use of the apostrophe ( ‘ ) symbol in SNMP community strings.

Except for the SNMP read-only community string and the username, the information on this page is encoded in a way that makes it unreadable outside of OmniCenter. If you think you may have set the wrong password or read-write string, the easiest way to fix the problem is simply to re-enter the correct string and click Apply Changes. Note that the username and local password can be controlled by different device templates, if desired.

An incorrectly configured read-only community string will return the same result as a device that is unreachable or that has filters preventing it from responding. This is a known limitation of the SNMP protocol and not specific to OmniCenter.

Host Tab

This tab contains three sections:

  • Alerting Options
  • Alert Contacts
  • Parent/Child

Alerting Options Section

The Alerting Options section contain settings that control availability monitoring. Fields that are controlled by device templates are indicated by a lock icon to the right of the field. Click the lock to allow editing of the controlling template.

You must click Update for any changes you make in this section to take effect.

The Alerting Options section of the Host tab controls host availability monitoring.
  • Host & Service Alarm Status
    This indicator/switch shows whether or not critical states for host availability checks and service checks will generate alarms for this device. Click the switch to disable monitoring of host and service checks. This setting performs exactly the same function as the “Host & Service Monitoring” indicator on the Main tab (above).
  • Renotify Interval
    This field specifies the number of minutes an incident generated by a failed host availability check will wait to be acknowledged or closed before running the next higher tier of action groups assigned in the Alert Contacts section (below). OmniCenter maintains a counter for the number of times the renotify interval has passed. When the amount of time specified in this field passes, the counter is incremented by one. The counter number correlates directly with the Alert Contacts escalation tier number. Setting a value of zero means that no matter how many times the renotify interval passes, only the action groups in escalation tier 1 will be run. A lock icon next to this field indicates that the setting is controlled by a device template. Click the lock icon to open the device template.
  • Disable Polling If Device Is Down Longer Than
    This field specifies the number of hours a host must be “down” before OmniCenter disables the device. Disabled devices are no longer monitored or alerted on. The purpose of this feature is to prevent redundant, unwanted alerting on devices that have been down for an excessively long time. Devices are disabled independently of incidents. So, it doesn’t matter if a host down incident has been acknowledged or not. If the host comes back up, it will be re-enabled in OmniCenter and monitoring and alerting will resume. Any associated incident will clear and close itself. A lock icon next to this field indicates that the setting is controlled by a device template. Click the lock icon to open the device template.

Alert Contacts Section

This section is for specifying the action groups that will be run when this device fails a host availability check. These action groups are called host alert contacts when assigned to a device in this way. Host alert contacts that are added by device templates are indicated by a lock icon to the right of the field. Click the lock to edit the controlling template. Host alert contacts are added cumulatively, and are not overridden by applied device templates.

Action groups that include contact methods added to a device as alert contacts will receive alert notifications (based on their escalation tier) if this host goes down.

This section is for managing the list of action groups that will be run for this device when a host-down condition occurs. Action groups used as alert contacts should typically contain notification actions, but may also contain command actions.

Alert contacts versus action groups

An “alert contact” is an action group that should contain at least one email, mobile or SMS notification method (i.e. the “contact”) and is assigned to an escalation tier.

Action group escalation for failed host checks follows a different convention than that used for other OmniCenter monitoring checks, where there’s only a single escalation ties and the action groups are specified per check. The escalation tier number (displayed in the table) represents the number of times the renotify interval (see Alerting Options above) has passed for a given host-down situation. Each time the renotify interval passes, the action groups in all escalation tiers of that number or below are run. For example, after the first renotify interval has passed, all tier 1 action groups (but only tier 1 groups) will be run. After the second renotify interval passes all tier 1 and tier 2 action groups will be run. After the third time, all tier 1, tier 2 and tier 3 action groups will be run. And, so on.

It’s highly recommended that the addition of alert contacts to devices be done through the use of device templates. However, action groups can be added as alert contacts directly to this device manually by clicking Add Contact. Alert contacts added manually can be edited and deleted from here, alert contacts added by device templates cannot.

Alert contacts added here can be edited and deleted by clicking the respective icons in their Actions column. Alert contacts with a lock icon in their Actions column are controlled by a device template. Click the lock icon to open the device template.

Parent/Child Sections

These sections display lists of layer 2/layer 3 parent and child devices connected to this device (layer 2 is CDP only). Along with the site device group that each device is a member of.

The Actions button above the parent list provide the options to (re)autodiscover this device’s parents (parents and children are autodiscovered when the device is first added to OmniCenter) or to manually add/edit parents.

Service Tab

The Service tab is where all service checks added to this device are managed, and has only one section, Service Checks.

The service checks list displays each service check added to this device, along with whether it’s an active or passive type check. A lock icon in the ACTIONS column indicate that the check was added, and is controlled by, a device template. Checks without a lock can be managed from within the list.

The service checks table lists all the service checks currently monitoring services on this device, as well as their type (active/passive). It is highly recommended that all service checks be added to devices through the use of device templates. However, the Actions button provides a way to manually add individual service checks if necessary, and is context sensitive to the device type (for example, Windows devices get the option to run the WMI service check wizard to add service checks for monitoring Windows services).

The columns and their descriptions are outlined below.

  • Description
    The name of the service check as supplied by the Description field in the service check. The table can be sorted by this column.
  • Type
    Indicates whether the service check is an active or passive check. See Service Checks for more information.
  • Actions
    This column contains icons representing actions that can be taken on the respective service check. The table below lists the actions typically available.
Icon Action
Edit Service Check – Allows you to edit an existing service check that has been directly added to this device. Service checks added to the device manually can be edited. Service checks added by device templates cannot.
Delete Service Check – Allows you to delete an existing service check that has been directly added to this device. Service checks added to the device manually can be deleted. Service checks added by device templates cannot.
Edit Device Template – Indicates that the service check is managed by a device template and cannot be edited directly. Click the lock to edit the controlling device template.

Instances Tab

The Instances tab is where performance threshold checks for interfaces and instances of the device are managed. It is also where the controllable settings for the device’s network interfaces can be changed. The Instances tab consists of multiple collapse panels, all of which are closed when the tab is first opened. Click on a panel to expand it. If a lock icon is displayed in the Actions column of any interface/instance, it means that the threshold check settings for that interface/instance are controlled by a device template. If you wish to change any threshold check settings for these interfaces/instances, click the lock icon to open the controlling device template.

The Instances administration tab for a router, showing the categories of performance statistics that can be monitored for it.

The header for each panel identifies the category of the performance statistics it manages, as well as the total number of threshold checks and the total number of instances managed within.

The Network Panel

The first panel is always the Network panel, which contains a listing of the device’s network interfaces and their associated instances. Once the panel is expanded it has three modes of display, selectable from a pull-down menu:

  • Active Interfaces – The list of interfaces that are being actively polled for data by OmniCenter. This list is a subset of the “All Interfaces” list below.
  • All Interfaces – The list of all interfaces that exist on the device (i.e. the device has assigned an index number to the interface).
  • All Thresholds – The list of instances associated with the interfaces in the Active Interfaces list above and any threshold check settings configured for them. When this option is selected, and additional drop-down appears allowing you to select: All, Active or Inactive (see the section “The Remaining Panels” below for information about these options).

These lists are only updated during a discovery poll. So if you make changes to interfaces on your device, be sure to repoll it (see Details section above). Otherwise those changes will not be reflected in the lists—potentially causing problems.

In order for an interface to be placed in the “Active Interfaces” list, it must meet several criteria:

  • Its “Operational Status” must be 1 (up).
  • Its “Administrative Status” must be 1 (up).
  • It must have a bandwidth speed (an override speed will be accepted).
  • It must not be filtered out of the list using the advanced filters. (Click Advanced Filters to construct complex filters to circumvent OmniCenter’s built-in logic for filtering interfaces on which to collect data.)

If the status of any of these items is changed for an interface on a device, the device must have a new discovery poll performed on it or the Active Interfaces list will not reflect the change.

Click Advanced Filters to open the Advanced Interface Filters page, where you can more precisely control which interfaces will be included in the Active Interfaces list. Use of this page is explained further below. Enter terms in the search box to act as a realtime filter for the table.

The contents of the table can be filtered in realtime using the search box next to the display mode selector.

The expanded Network panel, showing Active Interfaces.

When Active Interfaces is selected, you can manage several settings for each interface. The columns and their meanings are outlined below. (When All Thresholds is selected, see the section “The Remaining Panels” below for information about these options)

  • Description
    Displays a concatenation of the interface name and description as retrieved from the device during autodiscovery. Click the description to open a sub-panel that displays any bandwidth or errors-per-second threshold checks applied to this interface.
  • Index
    Displays the index number of this interface as assigned by the device.
  • Zoom
    Indicates whether or not this interface gets its own display on the Overview tab of the Device Dashboard. A checkmark means the interface displays, an X means it does not. Click to toggle the display of this interface. When the dashboard zoom is turned on, the tag Dashboard Zoom will be added to the interface tags. Turning it off will remove the tag. The tag can also be manually added and removed from the interface for the same effect. See Dashboard Zoom Interface Tag for more information.
  • Traffic
    Indicates whether or not this interface is displaying a traffic graph on the Traffic tab of the site dashboard for the site it belongs to. Be aware that the interface must also be configured from the device to export traffic flow information. This is indicated by a traffic flow icon in the same column (double arrows). A checkmark means the interface displays a traffic graph, an X means it does not. Click to toggle the display for this interface. When turned on, the tag Site Traffic will be added to the interface tags. Turning it off will remove the tag. The tag can also be manually added and removed from the interface for the same effect.
  • 1-Minute Polling
    Indicates if the interface is being polled at 1-minute intervals. Applies to 1 GB and faster interfaces only, which are automatically set to poll at 1-minute intervals. Click to turn off 1-minute polling for that interface.
  • IP Address
    Displays the IP address assigned to this interface.
  • Speed | In
    Displays the maximum bandwidth speed of this interface for inbound traffic, expressed as Megabits per second. This figure may be overridden to correct improperly scaled graph data using the plus icon in the ACTIONS column. Enter 0 as a bandwidth override to remove an override.
  • Speed | Out
    Displays the maximum bandwidth speed of this interface for outbound traffic, expressed as Megabits per second. This figure may be overridden to correct improperly scaled graph data using the plus icon in the ACTIONS column. Enter 0 as a bandwidth override to remove an override.
  • MAC Address
    Displays the MAC address of this interface.
  • Status Alert
    Indicates whether or not this interface has a passive interface status service check assigned. Click the edit icon at the top of the column to manually bulk edit passive interface status checks for this device.
  • Bandwidth | Poll
    Indicates whether or not this interface is being polled for bandwidth performance data.
  • Bandwidth | Thresh
    Indicates whether or not this interface is having its bandwidth performance monitored by a threshold check.
  • Errors | Poll
    Indicates whether or not this interface is being polled for error performance data.
  • Errors | Thresh
    Indicates whether or not this interface is having its error performance monitored by a threshold check.
  • Tag(s)
    Tags can be assigned to individual interfaces to make groups of interfaces easy to reference when generating reports. Click the edit icon at the top of the column to manually to bulk edit interface tags for this device.
  • Actions
    This column contains icons representing actions that can be taken on the respective interface. The table below lists the actions typically available.
Icon Action
Set Bandwidth Override – Allows you to manually override the autodetected bandwidth speed value for this interface (IN and OUT may be configured independently). This does not change the actual interface maximum speed! Only the value used for calculating performance is affected. Use this feature if your performance graph is displaying incorrectly scaled data. Click the icon and enter a speed to set a new max bandwidth speed. The icon will change to an edit icon. Click the icon and delete the entered override speed to re-detect the default speed. An automatic repoll of the device will be scheduled after each edit of the bandwidth speed. The page will need to be reloaded after a moment to view the updated max bandwidth figure in the Speed column. (These settings are always overridden by the Bandwidth Override setting in the Advanced part of the Details section on the Main tab, if it is configured.)
View Interface Graph – Opens the performance graph page for this interface, which displays graphs for bandwidth, errors and latency.

Advanced Interface Filters

Clicking Advanced Filters in the Network panel opens the Advanced Interface Filters page. Here you can manually construct a set of advanced filters to determine which device interfaces OmniCenter will display and manage in the “Active Interfaces” list on the Network panel. These filters will override OmniCenter’s default filtering for interfaces.

Use advanced filtering to override the interfaces OmniCenter displays by default.

The advanced filters page offers a wide variety of variables and operators with which to construct quit complex filtering. Select the variables, operators and values on which you would like to filter, and click Add Filter. Since you can’t use brackets to frame the statements, you must use the AND/OR options creatively. For example, if you wanted to see all the interfaces that include “gig” in their description, whether they are operationally up or down, you would have to create four filter statements such as the following:

Name/Variables Operators/Values Text Entry
Interface Description LIKE (PERL 5 REGEX) gig
AND
Interface Oper Status EQUALS (Numeric) 1
OR
Interface Description LIKE (PERL 5 REGEX) gig
AND
Interface Oper Status EQUALS (Numeric) 0

Up to five statements can be added at a time, but more can be added after each group. The filter operations are case-sensitive, so if you also need to search for “GIG” and “Gig” you will need an additional four statements for each case.

Advanced filter operations using text values are case-sensitive. So, you may need to create additional statements to cover values using a different case.

Constructing these filters properly can be quite challenging, and should only be attempted by advanced users.

After you’ve created a complete filter set (and any time you edit those filters), the device will need to have a discovery poll scheduled to update the interface list.

The Remaining Panels

The remaining panels display all other instances for the device organized by performance statistic categories, along with any threshold check settings configured for that instance. These panels have three modes of display for their tables, selectable from a drop-down:

  • All – Shows all instances for the device categorized under that metric, whether they have an active threshold check assigned or not.
  • Active – Shows only the instances with an active threshold check assigned.
  • Inactive – Shows only the instances with an inactive or no threshold check assigned.

In all display modes the contents of each table can be filtered in realtime using the search box next to the display mode selector. The columns and their meanings are explained below.

  • Active
    Indicates whether on not this instance has an active threshold check assigned to it.
  • Description
    The name of the instance as provided by the device. The table can be sorted by this column by clicking the column header.
  • Variable One
    Most resources are configured in pairs (variable one/variable two). See Threshold Checks for more information

    • High – Indicates the high threshold WARNING (yellow) and CRITICAL (red) settings for this variable, if either or both are set.
    • Low – Indicates the low threshold WARNING (yellow) and CRITICAL (red) settings for this variable, if either or both are set.
    • Anomaly – Indicates the anomaly WARNING (yellow) and CRITICAL (red) sensitivity settings for this variable, if either or both are set.
  • Variable Two
    Most resources are configured in pairs (variable one/variable two). See Threshold Checks for more information

    • High – Indicates the high threshold WARNING (yellow) and CRITICAL (red) settings for this variable, if either or both are set.
    • Low – Indicates the low threshold WARNING (yellow) and CRITICAL (red) settings for this variable, if either or both are set.
    • Anomaly – Indicates the anomaly WARNING (yellow) and CRITICAL (red) sensitivity settings for this variable, if either or both are set.
  • Contacts
    Indicates the number of action groups selected for the respective threshold check.
  • Actions
    This column contains icons representing actions that can be taken on the respective instance. The table below lists the actions typically available.
Icon Action
Add – Allows you to adds a threshold check directly to this instance. Can potentially be overridden by an applied device template.
Locked/Unlocked – Locked indicates that this threshold check is managed by a device template. Click the lock to unlock this specific threshold check and override the settings from the controlling device template. The icon will change to the unlocked icon. Clicking the unlocked icon will set the threshold back to locked, and allow the controlling device template to resume control of this threshold check and reconfigure its settings. (A report of which threshold checks have been unlocked on which devices can be found on the Device Templates Administration page.)
Edit – Allows you to edit an existing threshold check that has been directly added to the instance.
Template – Opens for editing the device template currently controlling this threshold check.

Documentation Tab

The Documentation tab lets an administrator associate arbitrary data with a specific device. Such data could include things like: who is responsible for this device, where is this device located, is there something special about this device that needs to be known when working with it, etc. The section and their uses are described below. Any changes on this tab need to be saved by clicking Apply Changes.

The device “Documentation” tab allows an administrator to attach arbitrary pieces of information to a particular device.
  • Device Note
    This section allows you to store any notes or information that don’t quite conform to any of the other sections. The information is stored as text only, and no formatting options are available.
  • Site & Location Information
    This section provide a place to store device geographical location. Geographical information supplied is purely anecdotal, and in no way affects this device’s site device group (although, the device’s site is pre-populated here for convenience).
  • Attributes
    This section allows you to add your own fields of type “x” and the values for those fields. This provides a completely open-ended way for an administrator to attach key/value data that is convenient to be associated with a device—directly to that device. Click the plus button to add additional attributes.
  • Reference Contacts
    This section provides a place to store the names and contact information of useful or important individuals who are in some way relevant to this particular device. Reference contacts added here are not accessible outside of this device, and don’t have anything to do with action groups or alerting in general. Click the plus button to add additional contacts.

Administrators can add as many attributes and reference contacts as desired. Creative administrators will doubtless find many useful ways in which to use this feature to store device-specific data.

For Local Device Reference Only

The “Site & Location Information” and “Reference Contacts” sections are for storing information for reference only. They are in no way connected to or associated with sites, alert notifications or action groups.
