About Cisco Unified Operations Manager

Cisco Unified Operations Manager (referred to as Operations Manager from this point forward) provides a unified view of the entire IP communications infrastructure. It presents the current operational status of each element of the IP communications network. Operations Manager continuously monitors the current operational status of different IP communications elements, such as:

• Cisco Unified Communications Manager

• Cisco Unified Communications Manager Express

• Cisco Unity®

• Cisco Unity Express

• Cisco Unified Contact Center

• Cisco Unified Contact Center Express

• Cisco Unified Presence Server

• Cisco Emergency Responder

• Cisco Unified MeetingPlace® Express

• Cisco gateways, routers, switches, and IP phones

Operations Manager also provides diagnostic capabilities for faster trouble isolation and resolution. It monitors and evaluates the current status of both the IP communications infrastructure and the underlying transport infrastructure in the network. It uses open interfaces such as Simple Network Management Protocol (SNMP), Hypertext Transfer Protocol (HTTP), and Windows Management Instrumentation (WMI) to remotely poll data from different devices in your IP communications deployment. Because Operations Manager does not deploy any agent software on the devices being monitored, it is nondisruptive to your system operations.

Managing Cisco Unified Communications Manager

For Operations Manager to manage Cisco Unified Communications Manager, you should add the latter to Operations Manager using Devices > Device Management > Add Devices. To add Cisco Unified Communications Manager, you need to keep the following information nearby:

• The IP address or hostname

• The SNMP read-only credentials

• The HTTP credentials: You only need credentials with read-level access to http://<server-name>/ccmadmin. For information on how to create a read-only Cisco Unified Communications Manager user account, see the User Guide for Cisco Unified Operations Manager 2.1, located on Cisco.com at http://www.cisco.com/en/US/products/ps6535/products_user_guide_list.html.

Once Cisco Unified Communications Manager has been added and Operations Manager has collected the required inventory details from the device, Operations Manager marks the device as Monitored. This signals that Cisco Unified Communications Manager has been successfully added and is being managed by Operations Manager.
If your devices are not going into the Monitored state, see the following topics from the Cisco Unified Operations Manager user guide:

Why Does a Device Go into the Partially Monitored State?

Why Does a Device Go into the Unreachable State?

Once Cisco Unified Communications Manager is in the Monitored State, you can open the Service Level View from the Operations Manager Monitoring Dashboard. You can find the Cisco Unified Communications Manager that you have just added in the tree view on the left by navigating to System Defined Groups > Cisco Unified Communications Applications > Communications Managers.

Figure 1. Entry Point for Managing Cisco Unified Communications Manager

Figure 1 shows one of the main entry points for managing the devices. By right-clicking the device in the tree view, you can see a list of context-sensitive tools that can be performed on that device. Figure 2 shows the list of context-sensitive tools.

Figure 2. List of Context-Sensitive Tools

In the remainder of this document, we will go through all of these tools in detail.

Basic Health Monitoring

Operations Manager monitors the system, environment, and application parameters of a Cisco Unified Communications Manager device listed in Table 1.

Table 1. Basic Health Monitoring

Monitored Parameters

Description

System

Usage of processor, hard disk, virtual memory, and RAM, along with status of interfaces on the Media Convergence Server (MCS) hosting Cisco Unified Communications Manager

Environment

Status of system fan, system temperature sensor, and system power supply of the MCS hosting Cisco Unified Communications Manager

Application

Status of all critical applications running on the Cisco Unified Communications Manager MCS

You can see the details of these parameters by launching the Detailed Device View right-click option on the device from the Service Level View.

Fault Monitoring

View the list of active alarms on Cisco Unified Communications Manager by launching the Alert Details right-click option on the device from the Service Level View. Clicking the Event ID option displays the event details, which indicate the exact nature of the event.
You can also view the alarm history on Cisco Unified Communications Manager by launching the Alert History right-click option on the device from the Service Level View.
Operations Manager performs monitoring and generates events on fault conditions detected on a Cisco Unified Communications Manager device. (See Table 2.)
To successfully receive Unified Communications Manager syslog messages, you must add the syslog receiver from the serviceability web page. For information on how to add the syslog receiver, see the User Guide for Cisco Unified Operations Manager 2.1, located on Cisco.com at http://www.cisco.com/en/US/products/ps6535/products_user_guide_list.html.
The events that are generated based on Syslog and RTMT (Real Time Monitoring Tool) polling are supported for certain Communications Manager releases. Please see the User Guide for Cisco Unified Operations Manager 2.1 for more details.

Table 2. Fault Monitoring

Fault Condition

Event Details

CPU pegging

CpuPegging

Event Description: This event occurs when the percentage of CPU load on a call processing server is over the configured percentage for the configured period of time. This event is generated based on polling RTMT precanned counters. To view the threshold, select Administration > Polling and Thresholds > Thresholds > RTMT.

Default Polling: 30 seconds

Default Threshold: Not Applicable

Recommended Actions: Check Cisco Unified Communications Manager Windows Task Manager or Real Time Monitoring Tool to verify CPU high utilization. The most common reason for this event is that one or more processes are using excessive CPU space. The event has information on which process is using the most CPU. Once the process is identified, you may want to take action, which could include restarting the process.

It is helpful to check the trace setting for that process. Using the detailed trace level is known to take up excessive CPU space. Also check for events such as the Code Yellow event, and launch Operations Manager synthetic tests such as Dial Tone Test to see if there is any impact on call processing. If so, you may want to take more drastic measures, such as stopping nonessential services or scheduling a restart of Cisco Unified Communications Manager service during off hours.

For more details, go to the following links: http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a00808ef0f4.shtml http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_tech_note09186a00807f32e9.shtml

Insufficient hard disk space

LogPartitionHighWaterMarkExceeded

Event Description: This event indicates that the percentage of used disk space in the log partition has exceeded the configured high water mark. This event is generated based on polling RTMT precanned counters. To view the threshold, select Administration > Polling and Thresholds > Thresholds > RTMT.

Default Polling Interval: 30 seconds

Default Threshold: Not Applicable

Recommended Actions: Log partition usage can be monitored from the RTMT "Disk Usage" precan page. It shows up as Common Partition. Check trace settings and also check for core dump files. Please note that core dump files are fairly large. Typically, a core dump file is 200 MB-300 MB in size, but it can also be 1 GB or 2 GB.

Please note that once the log partition disk usage goes above the high water mark threshold, Cisco Log Partition Monitoring Tool (LPM) will start deleting files to put log partition disk usage under the low water mark threshold. Since LPM may delete the trace/log/core dump files you want to keep, it is very important to act when you receive a LogPartitionLowWaterMarkExceeded alert. You can use Trace and Log Central (TLC) to download files and delete them from the server.

LogPartitionLowWaterMarkExceeded

Event Description: This event indicates that the percentage of used disk space in the log partition has exceeded the configured low water mark. This event is generated based on polling RTMT precanned counters.

Default Polling Interval: 30 seconds

Default Threshold: Not Applicable

Recommended Actions: See LogPartitionHighWaterMarkExceeded.

LowInactivePartitionAvailableDiskSpace

Event Description: This event indicates that the percentage of available disk space in the inactive partition is lower than the configured value. This event is generated based on polling RTMT precanned counters.

To view the threshold, select Administration > Polling and Thresholds > Thresholds > RTMT.

Default Polling Interval: 30 seconds

Default Threshold: Not Applicable

Recommended Actions: Since there are no user-manageable files in Inactive Partition, check the alert threshold. If the threshold is at the Cisco default, then contact the Cisco Technical Assistance Center (TAC) for guidance.

LowActivePartitionAvailableDiskSpace

Event Description: This event indicates that the percentage of available disk space in the active partition is lower than the configured value. This event is generated based on polling RTMT precanned counters.

To view the threshold, select Administration > Polling and Thresholds > Thresholds > RTMT.

Default Polling Interval: 30 seconds

Default Threshold: Not Applicable

Recommended Actions: Some of the symptoms of low active disk space are:

• CCM Admin page does not operate correctly.
• BAT does not operate correctly.
• RTMT does not operate correctly.

Since there are no user-manageable files in Active Partition, check the alert threshold. If the alert threshold is at the Cisco default, then contact Cisco TAC for guidance.

LowAvailableDiskSpace

Event Description: This event indicates that the percentage of available disk space is lower than the configured value. This event is generated based on polling RTMT precanned counters.

To view the threshold, select Administration > Polling and Thresholds > Thresholds > RTMT.

Default Polling Interval: 30 seconds

Default Threshold: Not Applicable

Recommended Actions: Check the available disk space percentage and delete unnecessary files.

Insufficient virtual memory

LowAvailableVirtualMemory

Event Description: This event occurs when the percentage of available virtual memory is lower than the configured value. This event indicates that the available virtual memory is running low. This event is generated based on polling RTMT precanned counters.

To view the threshold, select Administration > Polling and Thresholds > Thresholds > RTMT.

Default Polling Interval: 30 seconds

Default Threshold: Not Applicable

Recommended Actions: Check Cisco Unified Communications Manager Windows Task Manager or the RTMT tool to verify insufficient memory. This event may be due to a memory leak. It is important to identify which process is using excessive memory. Once the process is identified, if you suspect a memory leak (for example, if the memory usage for a process increases continually, or a process is using more memory than it should), you may want to restart that process.

LowSwapPartitionAvailableDiskSpace

Event Description: This event occurs when the percentage of available disk space of the swap partition is lower than the configured value. This event indicates that available swap partition is running low. Please note that the swap partition is part of virtual memory. Therefore, low available swap partition disk space also means low virtual memory. This event is generated based on polling RTMT precanned counters.

To view the threshold, select Administration > Polling and Thresholds > Thresholds > RTMT.

Default Polling Interval: 30 seconds

Default Threshold: Not Applicable

Recommended Actions: When you receive this event, you should find out how much swap space and virtual memory are still available. You should also find out find out which process is using the most memory. This event may be due to a memory leak. Once you determine that there is a memory leak and virtual memory is running low, you may want to restart the service after saving the necessary troubleshooting information. Please consult the Cisco TAC for further information.

System fan is down or degraded

FanDown

Event Description: This event indicates that a required fan is not operating correctly. The event is based on processing the SNMP trap cpqHeThermalSystemFanFailed received from monitored Cisco Unified Communications Managers.

Recommended Actions: Check the status of the reported power supply and monitor for recurrence.

A critical application stops running

ServiceDown

Event Description: This event is generated when one of the critical services (any of the services in the Detailed Device View) is not running. The problem could be due to someone manually stopping the service. If you intend to stop the service for a long period of time, disabling monitoring for the service is highly recommended and is needed to avoid this alert. Go to Service Level View > Detailed Device View, select the specific service, and change the managed state to False.

Default Polling Interval: 30 seconds

Default Threshold: Not Applicable

Recommended Actions: Identify which services are not running. You can start the service manually from the Administrator Service Control page.

Also, check to see if there are any core files. Download the core files, if any, as well as service trace files.

Cisco Unified Communications Manager has entered a Code Red state (call throttling)

Code Red

Event Description: This event indicates that Cisco Unified Communications Manager has remained in a Code Yellow state for an extended period and cannot recover. This event is generated by monitoring the syslog messages received from Unified Communications Manager.

Default Polling Interval: Not Applicable

Default Threshold: Not Applicable

Recommended Actions: When Cisco Unified Communications Manager enters a Code Red state, the Cisco Unified Communications Manager service restarts, which also produces a memory dump that may be helpful for analyzing the failure. Generally, repeated call throttling events require assistance from the Cisco TAC. Cisco Unified Communications Manager SDI and SDL trace files record call-throttling events and can provide useful information. The TAC will likely request these trace files for closer examination.

Cisco Unified Communications Manager has entered a Code Yellow state (call throttling)

Code Yellow

Event Description: This event is generated when Cisco Unified Communications Manager has initiated call throttling due to an unacceptably high delay in handling incoming calls. This event is generated by monitoring the syslog messages received from Unified Communications Manager.

Default Polling Interval: Not Applicable

Default Threshold: Not Applicable

Recommended Actions: While this event generates, check process CPU usage and memory usage. Check for call bursts and an increased number of registered devices (phones, gateways, and so on) generated. Continuously monitor to see if Cisco Unified Communications Manager is out of the Code Yellow state. You can launch synthetic tests such as the Dial Tone Test to check for any impact on call processing.

To try to circumvent the possibility of a Code Yellow event, consider the possible causes of a system overload, such as heavy call activity, low CPU availability to Cisco Unified Communications Manager, routing loops, disk I/O limitations, disk fragmentation, and so on, and investigate those possibilities.

Performance Monitoring

Operations Manager performs trending of the following categories on a Cisco Unified Communications Manager:

• Resource usage (CPU, memory, MTP resources, transcoder resources, MOH Multicast/Unicast resources, hardware/software conference resources, location bandwidth available, CTI links active)

• Call statistics (active calls)

• Trunk statistics (trunk usage at DS0 level, port usage, gateway statistics)

• Registered devices (hardware phones, MGCP gateways, analog devices)

You can view the performance report or graphs over the past 72 hours by launching the Performance right-click option on the device from the Service Level View, and then selecting the performance parameter that you want to view. You can view multiple performance reports or graphs in a single screen.
By default, performance polling for a Cisco Unified Communications Manager device is disabled in Operations Manager. To enable performance polling for a Cisco Unified Communications Manager device, launch the Polling Parameters Page as described, select Voice Utilization Settings as the parameter type, and then check the Polling Enabled check box. Click Apply for the changes to take effect.
You can also configure the thresholds for the performance parameters by launching the Thresholds Parameter Page and selecting Voice Utilization Settings as the parameter type.

Synthetic Tests

To set up synthetic tests, launch the Phone Registration Test/Dial Tone Test/End-to-End Call Test right-click option on the device from the Service Level View.

Phone Registration Test: Opens a connection with the selected Cisco Unified Communications Manager and registers a simulated IP phone. The test passes if the phone registration is successful.

Dial Tone Test: Simulates an off-hook state to the Cisco Unified Communications Manager and checks for receipt of a dial tone. The test passes if it receives a dial tone signal from the Cisco Unified Communications Manager.

End-to-End Call Test: Initiates a call to a second simulated or real IP phone. The test passes if it registers, goes off-hook, and places the call. There is a ring indication and the destination phone goes off-hook to accept the call.

These tests verify the functional availability of the supporting infrastructure and validate different configuration aspects such as route patterns, route lists, intercluster trunks, and gateway dial peers. You can run them on demand to rapidly troubleshoot issues related to connectivity (signaling/media stream) and voice quality, as well as call processing or dial-plan management issues. You can also run them on a scheduled basis for proactive monitoring.
To run a synthetic test, you must have the necessary number of simulated Cisco 7960 phones configured in the Cisco Unified Communications Manager database; however, if autoregistration is enabled in Cisco Unified Communications Manager, this step is not necessary. To define simulated phones in a Cisco Unified Communications Manager for the synthetic tests, do the following:

Step 1. Launch and log in to the Cisco Unified Communications Manager Administration page.

Step 2. From the Cisco Unified Communications Manager Administration page, select Device > Add a New Device.

Step 3. From the Device Type drop-down menu, select Phone. Click Next.

Step 4. Select Cisco 7960 as the phone type for the simulated phone. Click Next.

Step 5. In the Phone Configuration page, enter a MAC address between 00059a3b7700 and 00059a3b8aff. The tool automatically fills in the Description field. Other required fields are the Device Pool and Button Template. Use the defaults. Click Insert.

The new IP phone to be used in the synthetic test has now been created. Repeat this procedure to define the destination IP phone on the destination Cisco Unified Communications Manager, if the destination phone will be a simulated phone and not a real phone.
You can also run batch tests after deploying a patch or an upgrade on Cisco Unified Communications Manager or after a phone firmware upgrade. Batch tests serve as a quick and easy way to assess the dial-plan configuration defined for different partitions and locations. With batch tests, you can set up a rolling schedule to allow each real IP phone to be tested, but not all phones are tested at the same time. Go to http://www.cisco.com/en/US/docs/net_mgmt/cisco_unified_operations_manager/2.0.1/user/guide/useBatch.html for more information on batch tests.

When the device is in the Suspended state, it no longer communicates with Operations Manager. You might want to do this to avoid false alarms when the Cisco Unified Communications Manager is in Maintenance mode. You can also delete the Cisco Unified Communications Manager from Operations Manager by launching the Delete Device right-click option on the device from the Service Level View.

Recommendations on Monitoring Important Cisco Unified Communications Manager Components with Operations Manager

Recommendations on Performance Monitoring

We recommend that you generate daily graphs and seven-day reports for trend analysis. A seven-day report establishes a baseline for the Cisco Unified Communications Manager system.
To generate a daily graph, go to the Service Level View and launch the Performance right-click option on the device, then select the appropriate metric and time that you want to view. Operations Manager can give you a real-time graph over the past 72 hours.
You can generate a seven-day (or longer) report using Cisco Unified Service Statistics Manager.
As part of the Cisco Unified Communications Management Suite, Cisco Unified Service Statistics Manager extracts the data from Operations Manager and provides advanced statistics analysis and reporting capabilities for Cisco Unified Communications deployments.
The performance data is also stored as comma-separated values (CSV) files for a period of 72 hours, in the following location: C:\Program Files\CSCOpx\data\gsu\_#GSUdata#_. If you want data for a period of more than 72 hours, you must manually copy the CSV files to another location.

CPU Usage

View the performance report or graphs for Total CPU Usage (Percentage) on a Cisco Unified Communications Manager by launching the Performance right-click option on the device from the Service Level View. The Maximum and Average data provides trending information.
You can also view each processor's CPU utilization in 5-minute increments by launching the Detailed Device View right-click option on the device from the Service Level View.

Calls in Progress

View the number of calls that are currently in progress in Cisco Unified Communications Manager from the Cisco Unified Communications Manager Port and CPU Usage counters in the Detailed Device View. This number includes all active calls. If all calls that are in progress are connected, the number of calls in progress and the number of active calls will be the same.

Calls Active

This value represents the number of streaming connections that are currently active (in use); in other words, the number of calls that actually have a voice path connected.
Calls in setup mode or in teardown mode are not reported by this count.
View the performance report or graphs for Active Calls (Number) on a Cisco Unified Communications Manager by launching the Performance right-click option from the Service Level View.
The minimum and maximum of this value can also be collected over time for capacity planning purposes.
Real-time graphing of this parameter, compared with expected values based on historical data, is useful in detecting subtle system performance degradation (generally by detecting that the real-time number of calls active is below expected values compared to the same time-of-day/day-of-week baseline values).

Calls Attempted

This value represents the total number of calls attempted on a Cisco Unified Communications Manager. View the number of calls attempted in real time from the Cisco Unified Communications Manager Port and CPU Usage counters in the Detailed Device View.
This value must be collected over time and used to compute the Busiest Hour Call Attempt (BHCA) value.

Calls Completed

This value represents the total number of calls completed on a Cisco Unified Communications Manager. View the number of calls completed in real time from the Cisco Unified Communications Manager Port and CPU Usage counters in the Detailed Device View.
This value must be collected over time and used to compute the Busiest Hour Call Attempt (BHCA) value.

PRI Channels Active

This value represents the total number of B channels that are active. Collection of this data over time is used to understand call patterns and busy-hour peak calls. Baseline data can be used to detect real-time underutilization of circuits, an indication of possible system performance degradation (including otherwise hard-to-detect PSTN call routing or circuit-down conditions). Data trending allows for circuit growth and provisioning planning.

Reports

We recommend that the administrator generate the daily and weekly reports, described in this section, for trend analysis.

Events Report

To store or receive reports from email, select Reports > Alert and Event History > Export, select All events for the last 24 hours and All events for the last 24 hours, select the file format, and enter the location or email address (or both). CSV file format allows you to quickly sort the events based on event name or device name, to identify past outages and top issues in the network.

Phone Status Report

This report tracks changes in phone status and thus serves to document move, add, and change operations on IP phones. To store or receive reports from email, select Reports > IP Phones and Applications > IP Phone Status Changes > Export, for each IP Phone Status Changes report that you want to generate and save nightly, select a file format, and enter the location or email address (or both). CSV file format allows you quickly sort the reports based on report fields.

Other Phone Reports or Displays

The Phone Status Display on the Monitoring Dashboard provides instant access to IP phone and video-enabled IP phone outage information. You can also get information about an IP phone's and video-enabled IP phone's switch and port, and so on, allowing administrators to troubleshoot problems that may have wider scope (at the switch level) than just the IP phone.
Phone registration status must be monitored for sudden changes. If the registration status changes slightly and readjusts quickly over a short time frame, it could be indicative of a phone move, add, or change. A sudden smaller drop in phone registration count can be indicative of a localized outage; for instance, an access switch or a WAN circuit outage or malfunction. A significant drop in registered phone level requires immediate attention by the administrator. This display, especially, must be monitored before and after upgrades to ensure that the system is completely restored.

All CTI Application Reports

Go to Reports > IP Phones and Applications > All CTI Applications to view the status of the registered CTI applications and their connection details. This report is useful in monitoring mission-critical applications that reside on separate servers but integrate with Cisco Unified Communications Manager. These applications include Call Center applications offered through Cisco Unified Contact Center, Cisco Emergency Responder, or Cisco Unity Express in a centralized call processing-monitoring environment.

Inventory Analysis

Go to Reports > IP Phones and Applications > Inventory Analysis to create a flexible phone search filter. You can group the phone by remote site, individual server in the cluster, IP subnet, VLAN, or switch. This information can be useful during upgrades or controlled switchovers between the subscribers in the same Cisco Unified Communications Manager group, or after restoring network outages to ensure complete recovery of all devices.

Route List Report

Click the Route List Cloud icon in the Service Level View to view the route pattern that is associated with the route lists, route groups, and voice gateways. This report provides information about the use of the route pattern, route list, and route group. This can be used for dial plan optimization and for identifying opportunities for toll bypass.
