NimbostratusF5 Load balancer LVM Monitoring scenario - assistance
Dear Folks,
I'm from monitoring background and here to understand the possibility of getting a situation monitored.
Consider I have F5 loadbalancer pair (Active-Standby).
Appears there...

NimbostratusThe sync between the active and the standby is just to sync any changes in configuration between the active and the standby unit. If it shows "disconnected" it can be a couple of reasons and would be independent of the active unit being unavailable. The sync should be configured to use a different network than the fail over network. When there's an issue with the active unit - the F5 will issue a communications error alert via SNMP to whatever SNMP IP's you have configured. I'd be less concerned with the sync in a failover scenario - though if your F5 isn't set to auto sync, there is always a chance in a failover situation the standby unit won't have the right running config.

NimbostratusHickman,
Thanks , Would you help me with the questions asked for please.
-> Would like to know is there a specific OID that shall be monitored for SYNC status (or) Is there a trap that shall be triggered from the device end when the SYNC breaks.
-> How F5 loadbalancer hung situation handled as per monitoring standards? Would like to understand in depth on the possible breaks when a device turns hung to ensure we shall enable live monitoring feed for notification.
How customers handles such hung state situation for notification - question comes up since the device will not go down according to SNMP manager since it will be reacheable . Only connections drop/threshold drops.
As you havementioned in the post, there should be a trigger if it's hung. Interested to know such trigger.
Let me know if you have any questions on my look out please.
