How to Add a Device to OmniCenter Using Manual Add

The Manual Add tab of the Add a Device page.

See also, Adding Devices to OmniCenter

This procedure takes you through manually adding a single device to OmniCenter using the Manual Add option. Use these steps if you don’t want to wait for OmniCenter’s normally scheduled autodiscovery scan to automatically discover a new device on your network.

The Manual Add tab offers a complete set of configuration fields for configuring your new device as it’s being added to OmniCenter. You may use as many, or as few, of the configuration fields as desired. Additionally, there is an option switch to further configure the device using OmniCenter’s customizable autoconfiguration rulesets.

The only requirements for using Manual Add are a (user-selected) name for the device, an IP address or host name and an SNMP public string3. However, in order for a device to be successfully added to OmniCenter, OmniCenter must be able to authenticate with the device. This means that working authentication credentials must be supplied in the Manual Add options, or a pre-existing device template containing usable credentials for the device must be available in OmniCenter. (Obviously, the device must also be connected to the network and powered on.) If OmniCenter cannot find credentials that allow it to authenticate with the device, the device will not be added.

Procedure

To manually add a single device to OmniCenter:

  1. From the main menu, select Administration → Add Device → Manual.
  2. Select the Manual Add tab at the top of the page.
  3. In the Name field, enter the desired name for the new device. The name entered here will be used to represent the device in all dashboards and reports.
  4. In the IP Address or Hostname field, enter the IP address or host name of the device.
  5. In any remaining fields that you wish to use, enter the appropriate information or selections.
    • All remaining fields are optional. See below for a complete explanation of each field.
  6. Click the Add Device button.

You’ll see a message from OmniCenter that the device is being processed and should be added shortly.

If desired, you can begin adding additional devices to OmniCenter using Manual Add immediately. You do not need to wait for OmniCenter to process the last added device.

Accidental Duplicates

Devices added to OmniCenter using “Manual Add” will force the device to be added, using the settings provided. This means that it is possible to accidentally add the same device multiple times using different values. OmniCenter will not add a device if the Name and IP Address or Hostname fields both exactly match an existing managed device (even if it’s a totally different device). However, using different values in those fields will allow you to add the same device over and over again.

Required Device Configuration Fields

Name
The name of this device as it should appear in OmniCenter. No special characters are allowed, except underscore (_) and dash (-).

IP Address or Hostname
The IP address or host name of this device. Use the FQDN when entering a host name.

SNMP Public String
The SNMP public string to use for this device.

Optional Device Configuration Fields

Basic

Domain
The domain on which to find this device. Used for Windows devices.

Username
The username to use when logging into the device if you are configuring a Windows device or using TACACS/RADIUS style authentication. This is required for Windows devices using WMI or WinRM polling, and on network devices for configuration management and Looking Glass functions if TACACS or RADIUS is in use.

Local Password
The password to use in conjunction with the username specified for initial login to the device, or the first password to enter if no username is required. This is required for Windows devices using WMI or WinRM polling, and on network devices for configuration management and Looking Glass functions.

Enable Password
The enable-with password for network devices that use a second level of authentication to issue configuration commands. This is required for configuration management. Do not use this field when configuring Windows devices.

Category
The category device group this device should be assigned to.

Site
Select the site device group this device should be assigned to.

Type
The OmniCenter device type for this device.

Template
The OmniCenter device template that you would like to assign to this device at the “device” hierarchy level.

Advanced

Host Alert Contact
The action group (that contains a contact method) that will receive alert notifications if this device becomes unreachable. The “blackhole” action group is a default notification action group that does not generate any notifications. Note: If you do not select an action group here or in a device template applied to this device, you will NOT receive alert notifications when this device goes down!

Interface Filter
A Perl-5 compatible regular expression (PCRE*) (not case-sensitive) to filter the list of interfaces on this device for which performance statistics will be collected. The entered expression will be tested against the name and description of each interface on the device. Only names or descriptions that match this expression will be polled. For example, you might type “ethernet” if you only wanted to monitor “fast ethernet,” “gigabit ethernet,” and “ethernet” ports, but not serial ports, on a router. Omit the leading and trailing slashes (i.e., enter “ethernet” and not “/ethernet/”).

SNMP Version
The version of SNMP you would like to use for this device.

Parent
The layer-3 parent for this device from the list of currently managed devices. If you didn’t allow OmniCenter to autodiscover the devices on your network and are manually adding them now, this field won’t apply to the very first device you add manually—so make sure the first device you add is the parent of all other devices. Additional devices can then be added with a parent device.

Auto-Parenting
Leave this setting switched ON to dynamically detect and set the layer-3 parent(s) for this device. This won’t work for the very first device you configure (see Parent, above), nor will it work for any devices that are on the same subnet as the OmniCenter appliance.

Poll Device (SNMP/WMI)
Leave this setting switched ON to enable the collecting of performance statistics for this device.

Host & Service Monitoring
Leave this setting switched ON to enable monitoring for host and service outages on this device. You should generally leave this setting switched ON, unless you have a specific reason to switch it OFF.

Enable Thresholds
Leave this setting switched ON to enable threshold checks to be performed on collected performance data. You should generally leave this setting switched ON, unless you have a specific reason to switch it OFF.

Use Templates
Leave this setting switched ON to enable device templates to be applied to this device. Switching this setting OFF means that any device template selected above will be applied once, then forgotten—which is not recommended, except when applying default device templates as a one-time operation.

Run Auto Configuration Rules
Switch this setting to ON to process this device using OmniCenter’s autoconfiguration rulesets as it is added to OmniCenter.
