I am using CA APM 10.0 and facing the below warning in CEM, please assist me the steps to resolve this warning.
A couple of things to think about:
Do you have more than one TIM seeing the same traffic, in which case the same session id could be seen by more than one TIM. In which case traffic should be filtered so that each TIM sees different traffic in Setup > Web Server Filters.
Are you monitoring applications that actually have unique session identifiers, sometimes something is selected as a session identifier that is not unique at all.
Is the application timeout configuration in Business Application matching the actual session timeout of the application, if not, the value in Business Application should (probably be) increased to match.
David covered much of what I would. This is an information message so in theory it should be of concern. A good session identifier through the life of the transaction can eliminate this message as well as the unidentified user issue.
Your TIM and TIM Collector EM logs can give you more of a clue why this is happening
This is documented in Top Errors - CA Application Performance Management - 10.1 - CA Technologies Documentation
+1 for David's & Hal's comments
Some added info from my experiences with customer cases on this error:
Been meaning to write a KB on this for while as I remember I could never find one in the past, so here it is
