You can monitor user session activity
for web applications that are running on your server.
Name | Description |
---|---|
createCount | The number of sessions that were created. |
invalidateCount | The number of sessions that were invalidated. |
activeCount | The number of concurrently active sessions. A session is active if the WebSphere Application Server is currently processing a request that uses that session. |
liveCount | The number of local sessions that are currently cached in memory from the time at which this metric is enabled |
cacheDiscardCount | The number of session objects that have been forced out of the cache. A least recently used (LRU) algorithm removes old entries to make room for new sessions and cache misses. Applicable only for persistent sessions. |
affinityBreakCount | The number of requests that are received for sessions that were last accessed from another Web application. This value can indicate failover processing or a corrupt plug-in configuration. |
timeoutInvalidationCount | The number of sessions that are invalidated by timeout. |
activateNonExistSessionCount | The number of requests for a session that no longer exists, presumably because the session timed out. Use this counter to help determine if the timeout is too short. |
Depending on how you have deployed WebSphere eXtreme Scale you can enable HTTP client session statistics in one of the following ways:
