Configuration of performance counters in RTMT

The IM and Presence service directly updates Performance counters (called PerfMon counters). The counters contain simple, useful information, such as the number of subscriptions that are activated and number of PUBLISH messages that are processed.

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.

You can also enable troubleshooting perfmon data logging to automatically collect statistics from a set of perfmon counters that provide comprehensive information on the system state. Be aware that enabling troubleshooting perfmon data logging may impact system performance on the server.

How to view performance counters in RTMT

The Real-Time Monitoring Tool displays perfmon counters in chart or table format. The chart format displays the perfmon counter information by using line charts. For each category tab that you create, you can display up to six charts in the RTMT Perfmon Monitoring pane with up to three counters in one chart.

By default, RTMT displays perfmon counters in a chart format. You can also select to display the perfmon counters in a table format. To display the perfmon counters in table format, you need to check Present Data in Table View when you create a new category.

You can organize the perfmon counters to display a set of feature-based counters and save it in a category. After you save your RTMT profile, you can quickly access the counters that you are interested in. After you create a category, you cannot change the display from a chart format to a table format, or vice versa.

                      Troubleshoot 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 IM and Presence 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 five 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:

                      • Enable and disable the trace filter for Troubleshooting perfmon data logging.
                      • Monitor a set of predefined System and IM and Presence performance objects and counters on each server.
                      • Log the monitored performance data in CSV file format on the server in the active log partition in the var/log/active/cm/log/ris/csv directory. The log file uses the following naming convention: PerfMon_<node>_<month>_<day>_<year>_<hour>_<minute>.csv; for example, PerfMon_172.19.240.80_06_15_2005_11_25.csv. Specify the polling rate. This rate specifies the rate at which performance data is gathered and logged. You can configure the polling rate down to 5 seconds. Default polling rate equals 15 seconds.
                      • View the log file in graphical format by using the Microsoft Windows performance tool or by using the Performance Log viewer in the Real-Time Monitoring Tool.
                      • Specify the maximum number of log files that will be stored on disk. Log files exceeding this limit are purged automatically by removal of the oldest log file. The default specifies 50 files.
                      • Specify the rollover criteria of the log file based on the maximum size of the file in megabytes. The default value specifies 2 MB.
                      • Collect the Cisco RIS Data Collector PerfMonLog log file by using the Trace & Log Central feature of the Real-Time Monitoring Tool or Command Line Interface.

                      The troubleshooting perfmon data-logging feature collects information from counters within the perfmon objects.

                      Refer to Performance objects and counters for the system for a description of the counters.

                      Before You Begin
                      • Be aware that RISDC perfmon logging is also known as Troubleshooting Perfmon Data logging. When you enable RISDC perfmon logging, the server collects performance data that are used to troubleshoot problems.
                      • When you enable RIS Data Collector (RISDC) perfmon logs, the IM and Presence service collects information for the system in logs that are written on the IM and Presence server. You can enable or disable RISDC perfmon logs in Cisco Unified CM IM and Presence Administration by selecting System > Service Parameter and selecting the Cisco RIS Data Collector Service from the Service list box. By default, RISDC perfmon logging is enabled.
                      Procedure
                        Step 1   Select System > Service Parameters in Cisco Unified CM IM and Presence Administration.

                        From the list box, select True to enable or False to disable troubleshooting perfmon data logging. The default value specifies False.

                        Polling Rate

                        Enter the polling rate interval (in seconds). You can enter a value from 5 (minimum) to 300 (maximum). The default value specifies 15.

                        Maximum No. of Files

                        Enter the maximum number of Troubleshooting Perfmon Data Logging files that you want to store on disk. You can enter a value from 1 (minimum) up to 100 (maximum). The default value specifies 50.

                        Consider your storage capacity in configuring the Maximum No. of Files and Maximum File Size Parameters. Cisco recommends that you do not exceed a value of 100 MB when you multiply the Maximum Number of Files value by the Maximum File Size value.

                        When the number of files exceeds the maximum number of files that you specified in this field, the system deletes log files with the oldest timestamp.

                        Caution   

                        If you do not save the log files on another computer before you change this parameter, you risk losing the log files.

                        Maximum File Size (MB)

                        Enter the maximum file size (in megabytes) that you want to store in a perfmon log file before a new file is started. You can enter a value from 1 (minimum) to 500 (maximum). The default value specifies 2 MB.

                        Consider your storage capacity in configuring the Maximum No. of Files and Maximum File Size Parameters. Cisco recommends that you do not exceed a value of 100 MB when you multiply the Maximum Number of Files value by the Maximum File Size value.

                        Step 5   Select Save.

                        Troubleshooting Tips

                        You can collect the log files for Cisco RIS Data Collector service on the server by using RTMT to download the log files. If you want to download the log files by using the CLI, refer to Cisco Unified Communications Operating System Administration Guide. After you collect the log files, you can view the log file by using the Performance Log Viewer in RTMT or by using the Microsoft Windows performance tool.

                          Troubleshooting Tips

                          • The Real-Time Monitoring Tool saves the perfmon CSV log files in the log folder in the.jrtmt directory under the user home directory. In Windows, the path specifies D:\Documents and Settings\userA\.jrtmt\log, or in Linux, the path specifies /users/home/.jrtmt/log
                          • The RISDC perfmon logging is also known as Troubleshooting Perfmon Data logging. When you enable RISDC perfmon logging, the server collects data that are used to troubleshoot problems. Because the IM and Presence service collects a large amount of data in a short period of time, you should limit the time that RISDC perfmon data logging (troubleshooting perfmon data logging) is enabled.
                          • You can order each column by selecting on a column heading. The first time that you select on a column heading, the records display in ascending order. A small triangle pointing up indicates ascending order. If you select the column heading again, the records display in descending order. A small triangle pointing down indicates descending order. If you select the column heading one more time, the records displays in the unsorted state.
