[Version 5.0.2 and later]Welcome to Monitoring

Performance monitoring is an activity in which you collect and analyze data about the performance of your applications and their environment.

To help administrators identify application performance problems, the product collects performance data and supplies interfaces with which external applications can monitor the performance data; it also provides tools to display performance data for analysis.

Performance Monitoring Infrastructure (PMI)

The product collects data on run-time and applications through the Performance Monitoring Infrastructure (PMI), as described in Performance Monitoring Infrastructure . This infrastructure is compatible with and extends the JSR-077 specification.

PMI provides several types of interfaces to access performance data. Use these PMI interfaces to create tools that help monitor and tune performance.

Performance Monitoring Infrastructure (PMI) request metrics

IBM WebSphere Application Server also collects data by timing requests as they travel through the product components. PMI request metrics logs time spent in major components, such as Web Server, Web container, enterprise bean container, and database. These data points are recorded in logs and can be written to Application Response Monitoring (ARM) agents used by Tivoli tools or third-party monitoring tools.

For more information about PMI request metrics, see Measuring data requests (Performance Monitoring Infrastructure Request Metrics).
