Severity: 4-Minor


Sometimes the APM Dashboard will show the established session count to be greater than the total session count. The session count is transient and will be corrected on subsequent session events.


Dashboard momentarily shows inconsistent session count data until the next session event occurs.


If multiple sessions are created and/or terminated at the same time, it is likely that the same counter has different values in different TMM's but they have the same timestamp. So it is possible that an inconsistent value is picked.


Will be fixed when another session event (creation/termination of session) occurs.
