You can use the Tivoli Performance Viewer (TPV) to view Performance Monitoring Infrastructure (PMI) data in chart or table form.
Before you begin
TPV monitors the performance activity of all servers on a node. This article assumes that one or more servers have been created and are running on the node, and that PMI is enabled.Why and when to perform this task
You view performance modules when your server is experiencing performance problems. For example, a common performance problem occurs when individual sessions are too large. To help view data on a session, you can view the Servlet Session Manager PMI module and monitor the SessionObjectSize counter to make sure that Session Object Size is not too large.Performance modules are shown in the TPV current activity settings in the administrative console.
Steps for this task (dependent on configuration)
Each module has several counters associated with it. These counters are displayed in a table underneath the data chart or table. Selected counters are displayed in the chart or table. You can add or remove counters from the chart or table by selecting or deselecting the check box next to them. By default, the first three counters for each module are shown.
For example, a scale setting of .5 means that the counter is graphed as one-half its actual value. A scale setting of 2 means that the counter is graphed as twice its actual value. Scaling only applies to the graphed values and has no effect on the data displayed when viewing it in table form.
Counters based on absolute values cannot be reset and are not affected by clicking Reset to Zero.
