Configuring Voice Application Systems and Software for Use with Operations Manager

Table F-1 lists tasks that you must perform before Cisco Unified Operations Manager (Operations Manager) can successfully monitor Cisco voice application software.

Table F-1 Configuration Tasks by Application Software Version and System 

If you have the following voice application software...	On the following voice application systems...	You must perform the following tasks
Any voice application software that Operations Manager supports	Media Server	Setting a Media Server's SNMP Services Community String Rights
Cisco Unified Communications Manager 3.3 and later	Media Server	Changing the Cisco Unified Communications Manager Cluster Name

Changing the Cisco Unified Communications Manager Cluster Name

---

Note You must use this procedure only if you are running a media server with Cisco Unified Communications Manager 3.3 or later.

---

Operations Manager cannot manage two clusters with the same name. If you are managing multiple Cisco Unified Communications Manager clusters, you must change the default cluster name. Cisco Unified Communications Manager starting with 3.3 use the default cluster name StandAloneCluster.

---

Note For detailed instructions on configuring Cisco Unified Communications Manager, see the Cisco Unified Communications Manager documentation.

---

---

Step 1 Open the Cisco Unified Communications Manager Administration page.

Step 2 From the menu bar, select System, and choose Enterprise Parameters. The Enterprise Configuration page opens.

Step 3 In the Cluster ID field, enter a new cluster name.

Step 4 Click Update.

---

Setting a Media Server's SNMP Services Community String Rights

---

Note Use this procedure on media servers running voice application software.

---

Operations Manager cannot monitor supported voice applications running on a media server if community string rights for SNMP services are set to none. The SNMP queries will not succeed unless the rights for the community string are changed to read-only, read-write, or read-create.

---

Step 1 On the media server system, select Start > Settings > Control Panel > Administrative Tools > Services. The Services window opens.

Step 2 Double-click SNMP Service. The SNMP Services Properties window opens.

Step 3 Select the Security tab.

Step 4 Select Community String and click Edit.

Step 5 Change the rights from NONE to READ ONLY.

---

Note Operations Manager requires read-only rights. You are not required to set the rights to read-write or read-create.

---

---

Determining when to Issue a CCMHttpServiceInaccessible Event

---

Note The information in this topic applies to a Cisco Unified Communications Manager cluster, the nodes of which run Cisco Unified Communications Manager Release 4.0 or later only.

---

Operations Manager follows standard serviceability guidelines by querying the publisher in a Cisco Unified Communications Manager cluster. If the publisher rejects the query, Operations Manager generates the CCMHttpServiceInaccessible event for the cluster without querying other nodes (Cisco Unified Communications Managers) as per Cisco Unified Communications Manager serviceability guidelines.

Table F-2 explains how Operations Manager determines when to generate the CCMHttpServiceInaccessible event and what you can do to decrease the number of events.

Table F-2 Understanding and Responding to CCMHttpServiceInaccessible Events

Why Cisco Unified Communications Manager Might Reject a Query	How Operations Manager Handles a Rejected Query	How You Can Handle Specific Instances of These Events
Client request rate is higher than allowed by server.	•Retries for 4 minutes at 30-second intervals. •After 4 minutes, if the Cisco Unified Communications Manager continues to reject the query, Operations Manager writes an error message to the log file. •After an additional 4 minutes, if the query continues to fail, Operations Manager generates the CCMHttpServiceInaccessible event.	Check the Cisco Unified Communications Manager for high CPU usage. If the event occurs during polling, consider increasing Cisco Unified Communications Manager or cluster polling settings (see Table 18-7). See the Editing Polling Parameters. If event occurs during inventory collection. See the Viewing Device Details.
