[Version 5.0.1 and later]Monitoring performance

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

  1. Enable PMI services in the application server as described in Enabling performance monitoring services in the application server through the administrative console.
    To monitor performance data through the PMI interfaces, you must first enable the performance monitoring service through the administrative console before restarting the server.
  2. Collect the data.

    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.

    1. 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).
