Notes from the following
link by Ken Gottry and IBM support
page about request metrics.
- PMRM are transaction based recording unlike Performance Monitoring Infrastructure (PMI) that provides information about average system resource usage statistics with no correlation across WebSphere Components.
- Records are written to the system.out log of the app server that the request is made on.
- The webserver has it's own log to write transaction (http-plugin.log)
- The last two records record the servlet and response time and in the webserver log the size of the request and size of response are also recorded.
- Why use request metrics ?
- Request metrics allow you you to track individual transactions and the time in each WebSphere component.
- Request Metrics Filters
- Filters exists for
- EJB
- URI
- Source IP
- Web Services
- JMS Filters
- Allow you to focus on a specific area.
