Using Collection Services performance data
Collection Services, a component of WebSphere® Application Server for IBM® i, collects Performance Monitoring Infrastructure (PMI) data for stand-alone application servers. This PMI data is collected at specified intervals, providing a snapshot of activity during that time.
About this task
- QAPMWASCFG
Server configuration data. This data includes information about the different WebSphere Application Server jobs. This information is static and therefore does not change during life of the server. There is one record per server.
- Server data
One record is created for each active server job per interval. Much of the data comes from WebSphere Application Server PMI data and transaction counters.
- Application data
It contains one record for each application module per interval. WebSphere Application Server PMI counters are the source for many of the fields in this file. For the JavaServer Pages (JSP) section, the data in each field represents a sum over all JSPs running in a given application.
- QAPMWASEJB EJB data This data includes information about applications with Enterprise JavaBeans (EJB) running on the WebSphere Application Server. Each record represents one type of enterprise beans per application module per interval. If there is no bean activity for a particular EJB type, then no record is written.
- QAPMWASRSC
Pooled resource data. This data includes information about pooled resources associated with WebSphere Application Server. Each record represents one pooled resource per interval. The type of pooled resource might be a Java™ Database Connectivity (JDBC) connection pool, a J2EE Connector (J2C) connection pool, or a thread pool. Not all fields are applicable to each pooled resource type. If a resource exists but is not being used (nothing is created, destroyed, allocated or returned), no record is written.
