The following sections describe how to discover Cisco Unified Communications Manager (CUCM) clusters in SL1 using the Cisco: CUCM Unified Communications Manager PowerPack:

Discovering a CUCM Cluster

When you use the Cisco: CUCM Unified Communications Manager PowerPack to discover Cisco Unified CM devices, SL1 creates a device representing your Cisco Unified CM cluster. This cluster device acts as the root device for the remaining servers and component devices in your Cisco Unified CM system.

To create and run a discovery session that will discover a Cisco Unified CM cluster:

  1. On the Devices page () or the Discovery Sessions page (Devices > Discovery Sessions), click the Add Devices button. The Select page appears:

Image of the Add Devices wizard, page 1

  1. Click the Unguided Network Discovery button. Additional information about the requirements for discovery appears in the General Information pane to the right.
  1. Click Select. The Add Devices page appears.
  2. Complete the following fields:
  • Name. Type a unique name for this discovery session. This name is displayed in the list of discovery sessions on the Discovery Sessions tab.
  • Description. Optional. Type a short description of the discovery session. You can use the text in this description to search for the discovery session on the Discovery Sessions tab.
  • Select the organization to add discovered devices to. Select the name of the organization to which you want to add the discovered devices
  1. Click Next. The Credentials page of the Add Devices wizard appears:

Image of the Add Devices wizard, page 2

  1. On the Credentials page:
  • Select an SNMP credential to use with the Cisco Unified CM cluster. (For more information on SNMP credentials, see the section on Defining an SNMP Credential.).

An SNMP credential is needed only to properly classify the devices in the cluster. If SNMP is not available on the Cisco Unified CM cluster, then you do not need to select an SNMP credential; in that scenario, the root device will be discovered as a pingable device and you must manually change it to a Cisco Unified CM cluster.

  1. Click Next. The Discovery Session Details page of the Add Devices wizard appears:

Image of the Add Devices wizard, page 2

  1. Complete the following fields:
  • List of IPs/Hostnames. Type the IP addresses for the Cisco Unified CM Publishers.
  • Which collector will monitor these devices?. Required. Select an existing collector to monitor the discovered devices.
  • Run after save. Select this option to run this discovery session as soon as you save the session.
  1. Click Save and Run if you enabled the Run after save setting, or Save and Close to save the discovery session. The Discovery Sessions page (Devices > Discovery Sessions) displays the new discovery session.
  2. If you selected the Run after save option on this page, the discovery session runs, and the Discovery Logs page displays any relevant log messages. If the discovery session locates and adds any devices, the Discovery Logs page includes a link to the Device Investigator page for the discovered device.

NOTE: If you attempt to discover a CUCM cluster whose servers have been cloned from a separate CUCM cluster that has also been discovered within the same SL1 stack, the "Cisco: CUCM Subscriber Merge" Dynamic Application may incorrectly attempt to merge subscriber devices with components in another DCM tree. To avoid this, you must manually merge the subscriber server devices with their associated component devices in the correct cluster. The physical device of the CUCM Publisher should not be merged with its associated component device.

Discovering a CUCM Cluster in the SL1 Classic User Interface

When you use the Cisco: CUCM Unified Communications Manager PowerPack to discover Cisco Unified CM devices, SL1 creates a device representing your Cisco Unified CM cluster. This cluster device acts as the root device for the remaining servers and component devices in your Cisco Unified CM system.

To create and run a discovery session that will discover a Cisco Unified CM cluster:

  1. Go to the Discovery Control Panel page (System > Manage > Classic Discovery).

  1. Click the Create button to create a new discovery session. The Discovery Session Editor window appears.

  1. Enter values in the following fields:
  • IP Address/Hostname Discovery List. Type the IP addresses for the Cisco Unified CM Publishers.

To monitor Cisco Unified CM servers that are registered by name within their clusters, you might need to go to the Host File Entry Manager page (System > Customize > Host Files) and map the server names to their IP addresses if you do not have access to DNS for the Cisco Unified CM system you want to monitor. For Network Address Translation (NAT) environments, server hostnames should be mapped to external IP addresses. For more information, see the section Manually Creating Host File Entries for Cisco Unified CM Nodes.

  • SNMP Credential. Select an SNMP credential to use with the Cisco Unified CM cluster. (For more information on SNMP credentials, see the section on Defining an SNMP Credential.)

An SNMP credential is needed only to properly classify the devices in the cluster. If SNMP is not available on the Cisco Unified CM cluster, then you do not need to select an SNMP credential; in that scenario, the root device will be discovered as a pingable device and you must manually change it to a Cisco Unified CM cluster.

  1. You can enter values in the other fields on this page, but are not required to and can simply accept the default values. For more information about the other fields on this page, see the section on Discovery and Credentials.
  2. Click Save and then close the Discovery Session Editor window.
  3. The discovery session you created appears at the top of the Discovery Control Panel page. Click its lightning bolt icon () to run the discovery session.
  4. The Discovery Session window appears.
  5. When the Cisco Unified CM cluster is discovered, click its device icon () to view the Device Properties page for the Cisco Unified CM cluster.

NOTE: If you attempt to discover a CUCM cluster whose servers have been cloned from a separate CUCM cluster that has also been discovered within the same SL1 stack, the "Cisco: CUCM Subscriber Merge" DA may incorrectly attempt to merge subscriber devices with components in another DCM tree. To avoid this, you must manually merge the subscriber server devices with their associated component devices in the correct cluster. The physical device of the CUCM Publisher should not be merged with its associated component device.

Verifying Discovery and Dynamic Application Alignment

The Dynamic Applications for monitoring Cisco Unified CM are aligned during discovery.

To verify that SL1 has automatically aligned the correct Dynamic Applications:

  1. In the Devices page, locate the newly discovered Cisco Unified CM cluster and click on it to view the Device Investigator page.

  1. From the Device Investigator page for the Cisco Unified CM cluster, click the Collections tab. The Dynamic Application Collections page appears.

  1. The following Dynamic Applications should appear on the Dynamic Application Collections page for the Cisco Unified CM cluster:
  2. NOTE: It can take several minutes after discovery for Dynamic Applications to display on the Dynamic Application Collections page. If the listed Dynamic Applications do not display on this page, try clicking the Reset button.

  • Cisco: CUCM Cluster Information

  • Cisco: CUCM Cluster Root Cache
  • Cisco: CUCM CTI Device Cache
  • Cisco: CUCM H323 Trunk Cache
  • Cisco: CUCM Misc Perf Counters Fast Cache
  • Cisco: CUCM Misc Perf Counts Slow Cache
  • Cisco: CUCM Partition Cache
  • Cisco: CUCM Process Cache
  • Cisco: CUCM Service Performance Cache
  • Cisco: CUCM Service States Cache
  • Cisco: CUCM SIP Trunk Cache

Manually Aligning Dynamic Applications

If the Dynamic Applications have not been automatically aligned, you can align them manually.

To manually align Dynamic Applications:

  1. From the Device Manager page (Devices > Device Manager), find the Cisco Unified CM cluster and click its wrench icon ().
  2. From the Device Properties page for the Cisco Unified CM cluster, click the Collections tab.

  1. Click the Actions button and then click Add Dynamic Applications. The Dynamic Application Alignment page appears.

  1. In the Dynamic Applications field, select the Dynamic Application you want to align.
  2. In the Credentials field, select the SNMP credential you created for monitor the Cisco Unified CM cluster.
  3. Repeat steps 2-4 for the remaining Dynamic Applications to align with the device.

  1. After aligning the Dynamic Applications, click the Reset button and then click the plus icon (+) for the Dynamic Application. If collection for the Dynamic Application was successful, the graph icons () for the Dynamic Application are enabled.

  1. Click a graph icon () to view the collected data. The Configuration Report page will display the number of components of each type and the total number of components managed by the Cisco Unified CM cluster.

Viewing Component Devices

When SL1 performs collection for a Cisco Unified CM cluster, SL1 will create component devices for the components in the Cisco Unified CM cluster and align other Dynamic Applications to those component devices. Some of the Dynamic Applications aligned to the component devices will also be used to create additional component devices. All component devices appear in the Device Manager page just like devices discovered using the ScienceLogic discovery process.

In addition to the Devices page, you can view the Cisco Unified CM cluster and all associated component devices in the following places in the user interface

  • The Device Investigator Map page (click Map in the Device Investigator page) displays a map of a particular device and all of the devices with which it has parent-child relationships. Double-clicking any of the listed devices reloads the page to make the selected device the primary device.

  • The Device Components page (Devices > Device Components) displays a list of all root devices and component devices discovered by SL1. The Device Components page displays all root devices and component devices in an indented view, so you can easily view the hierarchy and relationships between child devices, parent devices, and root devices. To view the component devices associated with a Cisco Unified CM cluster, find the Cisco Unified CM cluster and select its plus icon (+).

  • The Component Map page (Classic Maps > Device Maps > Components) allows you to view devices by root node and view the relationships between root nodes, parent components, and child components in a map. This makes it easy to visualize and manage root nodes and their components. SL1 automatically updates the Component Map as new component devices are discovered. The platform also updates each map with the latest status and event information. To view the map for a Cisco Unified CM cluster, go to the Component Map page and select the map from the list in the left NavBar. To learn more about the Component Map page, see the section on Maps.
