we are seeing issues when there are multiple tmm processes running. The values in the statistics profile are different between the tmm processes.

Statistics Profiles

9.x, statistics profiles not CMP compatible

VS is not demoted if added to a virtual server.

10.0, statistics profiles are not fully CMP compatible. Each TMM instance uses a separate instance of the statistic profile. The cumulative counts are shown in the GUI and when polled via SNMP.

CMP Compatibility

by the way, you may consider whether istats is usable. anyway, istats is cmp compatible but it is not real time and not available via snmp.
