Monitoring performance

 

Overview

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:

  1. Enabling performance monitoring services in the Node Agent through the administrative console. To monitor performance data through the PMI interfaces, first enable the performance monitoring services through the administrative console before restarting the server. If running Network Deployment product, you need to enable PMI service on both the server and on the node agent before restarting the server and the node agent.

  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 in one of the following ways:

    1. Starting the Tivoli Performance Viewer.

    2. 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).
