Monitoring performance
WAS collects data on run-time and applications through the PMI. Performance data can then be monitored and analyzed with a variety of tools.
- Enable performance monitoring services in the appserver.
- If running in Network Deployment, enable PMI services on the node agents
- Restart the server and the node agent.
- Collect data.
The monitoring levels that determine which data counters are enabled can be set dynamically, without cycling the server. This can be done in one of the following ways...
- Enable performance monitoring services through Tivoli Performance Viewer
- Enable performance monitoring services using the command line.
WAS also collects data through PMI Request Metrics. This feature times requests as they travel through WebSphere Application Server components.
