Why and when to perform this task
WebSphere Application Server collects data on run time and applications through the Performance Monitoring Infrastructure (PMI). Performance data can then be monitored and analyzed with a variety of tools.
To set up performance monitoring:
Steps for this task
The monitoring levels that determine which data counters are enabled can be set dynamically, without restarting the server. You can set these values by Enabling performance monitoring services using the command line.
What to do next
WebSphere Application Server also collects data through PMI request metrics. This feature times requests as they travel through WebSphere Application Server components. For more information about PMI request metrics, see the topic Measuring data requests (Performance Monitoring Infrastructure Request Metrics).
