+title: F5 Big-IP: Cluster failover state
+agents: snmp
+catalog: hw/network/f5
+license: GPL
+distribution: check_mk
+description:
+ The check monitors the failover cluster state of F5 BIG-IP loadbalancers (local traffic
managers).
+ The default states are treated as follows:
+ unknown (0) is UNKNOWN,
+ offline (1) is CRIT,
+ forced offline (2) is CRIT,
+ standby (3) is OK,
+ active (4) is OK,
+
+ Moreover these levels are configurable.
+
+inventory:
+ One service is created.
