Fixed In:

Opened: Dec 10, 2016

Severity: 3-Major

Symptoms

The following MIB gauges are not reset after the device transitions from active to standby: F5-BIG-IP-APM-MIB::apmAccessStatCurrentActiveSessions F5-BIG-IP-APM-MIB::apmAccessStatCurrentEndedSessions F5-BIG-IP-APM-MIB::apmPaStatCurrentActiveSessions F5-BIG-IP-APM-MIB::apmPaStatCurrentPendingSessions F5-BIG-IP-APM-MIB::apmPaStatCurrentCompletedSessions

Impact

Since these gauges represent current session counts, administrator may not be able to identify the active device by looking at these gauges.

Conditions

After failover happens

Workaround

None

Fix Information

Now the SNMP counters and statistics for APM sessions are reset to 0 when a device transitions from active to standby. This change impacts both SNMP and command "tmsh show apm profile access".
