I have added an option, -n, which makes +# the expected state to be OFFLINE rather than ONLINE so you can run the +# plugin on both sides of the cluster and will receive critical alerts when +# the cluster fails over i.e. a proper failover will make the standby node +# go from OFFLINE to ONLINE for the group, so an ONLINE status should alert +# you!
