How to Monitor Web Container Sessions for WebSphere Traditional and Liberty Profile

WebSphere Traditional Base or ND Application Server:

Enable PMI request metrics and setup utilize the Servlet session counters in WebSphere Traditional along with TPV.

Register and report usage metrics to the IBM Cloud Private metering service

Enable PMI using the administrative console

Monitor performance with Tivoli Performance Viewer

Use request metrics to measure application flow

CreateCount

The total number of sessions created.

LiveCount

The total number of sessions that are currently cached in memory.

ActiveCount

The total number of concurrently active sessions. A session is active if Liberty is processing a request that uses that session.

InvalidatedCount

The total number of sessions that are invalidated.

InvalidatedCountbyTimeout

The total number of sessions invalidated by a timeout.

Caveate:  WSAdmin is not generally used for Monitoring Performance Statistics, but moreover it is used for Administration Configuration Setup.
