F5 Active Failover Status

Hello All, I am looking for some help here, I am trying to find out when and how the Active device in HA pair went to Standby. And now, it is still on standby and did not become active. Its a virtual F5 instance and the monitoring is being done by a different team. Also, I need some suggestion on how to monitor these devices if I can do any at my end? Its very difficult to keep an eye on it as each time I have to login to it and see the device status and everything up and running. Any input will be greatly appreciated.

 

Thanks in advance.

    Hello, 

you can do it in different ways:

-> SNMP:
https://support.f5.com/csp/article/K14399

n BIG-IP 11.2.0 and later, the F5-BIGIP-SYSTEM-MIB file contains the sysCmFailoverStatusId object identifier (OID) (1.3.6.1.4.1.3375.2.1.14.3.1) that can be queried through SNMP to determine the failover status of a BIG-IP system in a device group. The sysCmFailoverStatusId uses an integer value to represent the status of the BIG-IP system. The following table provides the possible values for this OID:

Value   Failover Status Description
0   unknown The failover status of the device is unknown
1   offline The device is offline
2   forcedOffline   The device is forced offline
3   standby The device is standby
4   active  The device is active

-> Via syslog:
You can send logs to a syslog servers (elastic search by example) and track some words (create notification)...
