PMI settings are being turned off during runtime
 Technote (FAQ)
 
Problem
The Performance Monitoring Service is enabled. Startup is checked and the initial specification level is set to standard and it is confirmed that the Runtime-Tab has the same settings.

All works fine until a few days later when the settings at the Runtime-Tab have changed to custom (servletSessionsModule is set to "N") but the settings at the Configuration- Tab remain the same, set to standard (all modules are set to "H").

This change prevents us from getting any information about the sessions.
 
Cause
A third party PMI viewer made a change to the servletSessionsModule setting which shows in the server.xml file. The string for ServletSessionsModule was spelled incorrectly in the server.xml file.

It should be: 'ServletSessionsModule=H'
instead it is: 'ServletSessionModule=H', notice the missing "s" on Sessions.

Note: This error is not limited to servletSessionsModule. Any PMI category that is misspelled may cause this problem.

 
Solution
Update the server.xml file to ensure that ServletSessionsModule is spelled correctly and set properly.

Note:Editing the PMI settings in the server.xml file directly using an editor or a third party product is not recommended. It is recommended and much less error prone to use a wsadmin command or the WebSphere® Administrative Console.
