Site Device Groups

Description

Netreo uses device groups to organize your monitored devices into administratively manageable sets. This allows you to view, select and edit an entire set of devices as a group. There are three types of device group available to which a device may be added: category, site and strategic group.

Every device monitored by Netreo always belongs to exactly one category and one site group. A device may also be added to any number of strategic groups. However, no device is required to belong to any strategic group.

Site device groups are used to organize your devices into arbitrary groups based on the concept of location. A site may be a physical geographic location (such as a street address), but it can just as easily be a theoretical system of organizing your network’s equipment (such as a department or building floor).

If a site is configured with latitude and longitude location coordinates, OmniCenter will display the site as a map pin in the Geographic Map dashboard widget. If a site is not configured with a latitude and longitude, but is provided with a proper street address, OmniCenter will automatically attempt to retrieve a latitude and longitude for it using an external geocoding API. (OmniCenter must be able to communicate with the external geocoding application for this to work. See the OmniCenter Firewall Requirements for more information.) This feature may be turned off if you wish to use a different paradigm for your site organization.

Sites using location coordinates may also be configured to display connections with other sites (which must also also have location coordinates). The Geographic Map widget will then draw lines between the pins of all connected sites, which may then be configured to display performance metrics.

Sites with location coordinates displayed in the Geographic Map widget and showing connections to each other.

Sites without location coordinates will not display on the Geographic Map widget. Although, they will still be fully functional in every other way within OmniCenter.

A unique feature of sites is the ability to store arbitrary data in the form of site documentation information. This data consists of key/value pairs stored in the site configuration. There is no way to retrieve or view this data outside of the site’s configuration settings, so it is only available to users with the SuperAdmin access level.

Site Management

Only users with the SuperAdmin access level may create and manage sites.

Sites (and their subnets) are initially added to OmniCenter during deployment using the setup wizard, but additional sites can be added at any time to suit your organizational needs.

OmniCenter will attempt to automatically place newly discovered devices into sites based on their subnet if that subnet is associated with a configured site. If OmniCenter cannot determine a site for a newly discovered device, it is placed into the “Unknown” site.

Every device managed by OmniCenter always belongs to exactly one site.

Devices may be reassigned to a different site at any time.

Although individual devices can be assigned to a site manually, it is often far easier to add a subnet to a site and let OmniCenter assign any new devices discovered in that subnet to the site automatically.

Create a new site

  1. Go the the OmniCenter main menu and select Administration > Grouping > Site to open the Site Administration page.
  2. Select Add a Site.
  3. In the SITE NAME field enter a name for your new site.
  4. If you wish your site to show up on the Geographic Map widget, either:
    • Enter the latitude and longitude of the site into the appropriate fields and switch OVERRIDE AUTOMATIC GEOCODING to ON.
    • Or, enter the street address of your site into the appropriate fields and make sure that OVERRIDE AUTOMATIC GEOCODING is switched to OFF.
  5. If you wish manually set the time zone for your site, switch AUTOMATICALLY SET TIMEZONE to OFF and select the desired time zone in the TIMEZONE SETTING field.
  6. (Optional) Select a device template to associate with this site.
    • You can add or change the device template associated with this site later, if desired.
  7. (Optional) Select an uploaded custom map to associate with this site.
    • You can add or change the custom map associated with this site later, if desired.
  8. (Optional) Select a custom dashboard to associate with this site.
    • You can add or change the custom dashboard associated with this site later, if desired.
  9. (Optional) Select other sites to connect to this site on the Geographic Map widget.
    • You can add or change the sites connected to this site later, if desired.
  10. (Optional) If this site uses IP Telephony, switch on the IPTEL options to allow OmniCenter to collect IP Telephony data and show related statistics on the site dashboard.
  11. Select Save Site.

Edit a site

  1. Go the the OmniCenter main menu and select Administration > Grouping > Site to open the Site Administration page.
  2. Locate the site that you wish to edit in the Current Sites table.
  3. Select the edit icon for that site in the ACTIONS column.
  4. Edit the site parameters as desired.
  5. Select Update Site.

Delete a site

  1. Go the the OmniCenter main menu and select Administration > Grouping > Site to open the Site Administration page.
  2. Locate the site that you wish to delete in the Current Sites table.
  3. Select the edit icon for that site in the ACTIONS column.
  4. Select OK at the prompt.
  5. The site is removed from OmniCenter and all devices currently in that site are placed into the “Unknown” site.

Deleting a site will cause all devices currently assigned to that site to be moved into the “Unknown” site. Therefore, for convenience, it is recommended that all affected devices be reassigned before deleting the site.

Assign devices to a site

  1. Go the the OmniCenter main menu and select Administration > Grouping > Site to open the Site Administration page.
  2. Locate the site that you wish to edit in the Current Sites table.
  3. Select the edit icon for that site in the ACTIONS column.
  4. On the edit page select the Devices tab.
  5. In the Select Devices to Add panel select a functional group to display the devices in that group.
    • None shows devices that belong to no functional groups.
    • Everything shows all devices monitored by OmniCenter.
  6. Select the checkbox for each device to be added to the site.
    • Selected devices remain selected when searching or navigating the table.
  7. Select Add To Site. The selected devices are reassigned to this site and appear in the Devices in Site panel.
  8. Select more devices to assign or simply navigate away from the edit page when finished.

These steps are for assigning devices to a site manually from Site Administration. In general, you will want devices to be assigned to site automatically when they are added for monitoring using auto-configuration rules.

Devices may also be assigned to a site manually from the administrative view of the device dashboard.

Assign subnets to a site

  1. Go the the OmniCenter main menu and select Administration > Grouping > Site to open the Site Administration page.
  2. Locate the site to which you wish to add subnets in the Current Sites table.
  3. Select the edit icon for that site in the ACTIONS column.
  4. On the edit page select the Subnets tab.
  5. Select Add Subnet.
  6. For each subnet you wish to add to the site (select the + icon next to the bottom subnet to increase the number of subnets available to add):
    1. Enter the address of the subnet.
    2. Enter the minimum CIDR prefix.
    3. If you do not wish OmniCenter to automatically scan this subnet for new devices as part of its routine subnet scan, uncheck the Auto Scan field. (This can be changed at any time later.)
  7. Select Add Subnets.

When OmniCenter performs its routine device discovery scan, any devices discovered in the subnets of a site are automatically assigned to that site.

Delete a subnet from a site

It may be more useful to disable automatic device scanning for a subnet rather than deleting it.

  1. Go the the OmniCenter main menu and select Administration > Grouping > Site to open the Site Administration page.
  2. Locate the site from which you wish to delete a subnet in the Current Sites table.
  3. Select the edit icon for that site in the ACTIONS column.
  4. On the edit page select the Subnets tab.
  5. Locate the subnet you want to delete in the Subnets table.
  6. Select the delete icon in the subnet’s ACTIONS column.
  7. The subnet is removed from the site.

Disable automatic device scanning for a subnet

  1. Go the the OmniCenter main menu and select Administration > Grouping > Site to open the Site Administration page.
  2. Locate the site for which you wish to disable a subnet in the Current Sites table.
  3. Select the edit icon for that site in the ACTIONS column.
  4. On the edit page select the Subnets tab.
  5. Locate the subnet you want to disable in the Subnets table.
  6. Switch the AUTO SCAN field for the subnet to OFF.
  7. Select Save.

Assign a device template to a site

  1. Go the the OmniCenter main menu and select Administration > Grouping > Site to open the Site Administration page.
  2. Locate the site that you wish to assign a device template to in the Current Sites table.
  3. Select the edit icon for that site in the ACTIONS column.
  4. In the TEMPLATE field select the device template to assign to this site.
  5. Select Update Site.

See the entry for Device Templates to learn more about device templates and their use.

Assign a custom dashboard to a site

  1. Go the the OmniCenter main menu and select Administration > Grouping > Site to open the Site Administration page.
  2. Locate the site that you wish to assign a custom dashboard to in the Current Categories table.
  3. Select the edit icon for that site in the ACTIONS column.
  4. In the CUSTOM DASHBOARD field select the custom dashboard to assign to this site.
  5. Select Update Site.

See the entry for Custom Dashboards to learn more about custom dashboards and their use.
