F5 Big-IP: Active/Active or Passive/Active Cluster Status (< V11.2)
|Distribution:||official part of Check_MK|
The check queries the MIB tables of F5 BIG-IP loadbalancers (local traffic managers) to identify
if the cluster correctly runs in an active/active or an active/passive setup.
You can configure the expected behaviour via a WATO rule.
It will issue a warning if the cluster setup differs from the expected setup.
This check is expected to be run on cluster hosts, since it evaluates the state of multiple nodes.
If you run this check on a cluster node, it will raise no warning if the cluster node state
differs from active.
Since version 11.2 you are able to configure the node states. Default values are:
unknown will be treated as UNKNOWN, offline as CRIT, forced offline as CRIT,
standby as OK and active as OK.
One service is created.
