 Description   

F5 template

Contains misconfiguration on triggers:

{TEMPLATE_NAME:bigip.memory.used[{#HOST.ID}].max(5m)}/{Big-IP SNMP:bigip.memory.total[{#HOST.ID}].min(5m)}*100>{$BIGIP.MEMORY.UTIL.WARN.MAX}

and

{TEMPLATE_NAME:bigip.memory.used.swap[{#HOST.ID}].max(5m)}/{Big-IP SNMP:bigip.memory.total.swap[{#HOST.ID}].min(5m)}*100>{$BIGIP.SWAP.UTIL.WARN.MAX}

on the xx.memory.total.xx.min(5m) expression.
Both items have discard_unchanged_heartbeat :

F5 BIG-IP: Host [{#HOST.ID}]: Total memory
F5 BIG-IP: Host [{#HOST.ID}]: Total swap

However, thus the triggers enter a not supported state, as the values do not usually change more than once in an hour.
Best workaround is to use xxxxx.last() instead of xxxx.min(5m).
