Specifying performance statistics to monitor

You can specify single statistics, multiple statistics, or groups of related statistics for monitoring through the Performance Monitoring Infrastructure by using the administrative console.

Before you begin

Ensure that you have enabled performance monitoring, and that you have at least once invoked the event you want to monitor before performing this task.
Procedure
  1. Open the administrative console.
  2. Select Monitoring and Tuning > Performance Monitoring Infrastructure.
  3. Select the server or node agent that contains the event points that you want to monitor.
    Note: You cannot choose to monitor statistics on a cluster; you can only do so on a specific server or node.
  4. Expand some of the groups, such as WBIStats.RootGroup or Enterprise Beans. All of the statistics that can be monitored are within the listed groups. Some statistics may not be listed because they have not been invoked since the server was last started.
  5. Select a statistic you want to monitor from within the tree on the left side of the panel, and then select the statistics that you want to collect on the right side, then click Enable. Repeat this for all statistics that you want to monitor.
  6. Go back to the server PMI configuration page by clicking the server name link.
  7. Click Apply or OK.
  8. Click Save.

Results

You can now start monitoring the performance of your chosen statistics in the Tivoli® Performance Viewer.
Note: When viewing these statistics, you should not mix counter-type statistics with duration-type statistics. Counters are cumulative, and the scales against which they are graphed them can quickly grow depending on your application. Duration statistics, in contrast, tend to remain within a certain range because they represent the average amount of time that it takes your system to process each event. Consequently, the disparity between the statistics and their relative scales may cause one or the other type of statistic to appear skewed in the viewer graph.
