Understanding Performance Monitoring
Cisco Unified Communications Manager directly updates Performance counters (called PerfMon counters). The counters contain simple, useful information on the system and devices on the system, such as number of registered phones, number of active calls, and number of available conference bridge resources.
The Cisco CallManager object contains most of the Cisco Unified Communications Manager performance counters, and these counters have only one instance. The instance-based counters that belong to the other objects can have zero or more instances. For example, if two phones are registered to Cisco Unified Communications Manager, two instances of each counter that belong to the Cisco phones object exist.
You can monitor the performance of the components of the system and the components for the application on the system by choosing the counters for any object by using RTMT. The counters for each object display when the folder expands.
You can log perfmon counters locally on the computer and use the performance log viewer in RTMT to display the perfmon CSV log files that you collected or the Realtime Information Server Data Collection (RISDC) perfmon logs.

Using RTMT for Performance Monitoring
RTMT integrates with Cisco Unified Communications Manager administration and serviceability software. RTMT displays performance information for all Cisco Unified Communications Manager components.RTMT provides alert notification for troubleshooting performance. It also periodically polls performance counter to display data for that counter. Refer to "Displaying a Counter Description" section on page 5-7 for examples on displaying perfmon counters in a chart or table format.
Perfmon monitoring allows you to perform the following tasks:
•
•
•
•
•
RTMT displays performance counters in chart or table format. Chart format looks like a miniature window of information. Up to six charts display in the RTMT performance monitoring pane for each category tab that you create. You can display a particular counter by double clicking the counter in the perfmon monitoring pane. Because chart view represents the default, you configure the performance counters to display in table format when you create a category.
You can remove a counter chart (table entry) with the Remove Chart/TableEntry menu item in the Perfmon menu in the menu bar.
Tip
For more information on Service Parameters, refer to Cisco Unified Communications Manager Administration Guide.See the following sections for configuration options in the RTMT perfmon monitoring pane:
•
Category Tabs
A category comprises a group of monitored performance counters. A tab in the RTMT monitoring pane contains the category name. All performance counters that are monitored in this tab belong to a category. The system polls the performance counters in the tab at the same rate, with each category configured to have its own polling rate.
You can create custom categories in the RTMT monitoring pane to view information that helps you troubleshoot specific performance, system, or device problems. If your system is experiencing performance problems with specific objects, create custom categories to monitor the performance of the counters within the object. If the system is experiencing problems with specific devices, create custom categories to monitor the devices in your system. In addition, you can create alert notifications for counters and gateways in these custom categories. To create custom categories, you add a new category tab. When the tab is created, you specify the specific performance counters, devices, and alerts within that tab and then save your custom category by using Profile.

Note
Adding Counters to Monitor
To troubleshoot system performance problems, you add the counter that is associated with the perfmon object to the RTMT performance monitoring pane, which displays a chart for the counter. Before you add counters, see the "Category Tabs" section.
Category tabs contain up to six perfmon counter charts.
Alert Notification for Counters
Using the alert notification feature, the application notifies you of system problems. Perform the following configuration setup to activate alert notifications for a system counter:
•
•
•
•
•
Zoom Counter
To get a closer look at performance monitors, zoom the monitor counter in the RTMT perfmon monitoring pane by highlighting the counter chart and choosing System > Performance > Zoom Chart.
Counter Properties
Counter properties allow you to display a description of the counter and configure data-sampling parameters.
The Counter Property window contains the option to configure data samples for a counter. The performance counters that display in the RTMT performance monitoring pane contain green dots that represent samples of data over time. You can configure the number of data samples to collect and the number of data points to show in the chart. After the data sample is configured, view the information by using the View All Data/View Current Data menu option to view all the data that a perfmon counter collected.

Troubleshooting Perfmon Data Logging
The troubleshooting perfmon data logging feature assists Cisco TAC in identifying system problems. When you enable troubleshooting perfmon data logging, you initiate the collection of a set of Cisco Unified Communications Manager and operating system performance statistics on the selected node. The statistics that are collected include comprehensive information that can be used for system diagnosis.
The system automatically enables troubleshooting perfmon data logging to collect statistics from a set of perfmon counters that provides comprehensive information on the system state. When Troubleshooting Perfmon Data Logging is enabled, Cisco estimates that the system experiences a less than 5-percent increase in CPU utilization and an insignificant increase in the amount of memory that is being used, and it writes approximately 50 MB of information to the log files daily.
You can perform the following administrative tasks with the troubleshooting perfmon data logging feature:
•
•
•
•
•
•
•
For more information on configuring Troubleshooting Perfmon Data Logging, see "Configuring Troubleshooting Perfmon Data Logging" section on page 5-13.
The troubleshooting perfmon data-logging feature collects information from the following counters within the following perfmon objects.
Refer to the Performance Objects and Counters for Cisco Unified Communications Manager for a description on the counters:
