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.
Steps for this task
- Open the administrative console.
- Click Servers > Application Servers in the console navigation tree.
- Click server_name.
- Click the Runtime tab.
- Click Performance Monitoring Infrastructure under Performance.
- Select Custom.
- Expand WBIStats.RootGroup (for process server service component events) or SCAStats.RootGroup (for Service Component Architecture-specific statistics). All of the statistics that can be monitored are within these groups. Some statistics may not be listed because they have not been invoked since the process server was last started.
- 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 and click Enable. Repeat this for all statistics that you want to monitor.
- Go back to the server PMI configuration page by clicking the server name link.
- Click Apply or OK.
- Click Save.
Result
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.
