[Pacemaker] Transition trigger for alarming

[Keith Ouellette]

We am using Nagios for network monitoring and for Pacemaker, we are using check_crm to provide status for nagios. This works very well if the failure is still seen by Pacemaker at the time nagios polls. If the failure condidtion causes a switchover, but the recovery is before the nest Nagios poll, Nagios does not report any issue, because there isn't one at the time of the poll, even if the transition of the resource changed to another node.



Is there a way to know that the transistion occured without scraping the messages log in a set interval and looking for only new events that state a transition or "Members Joined"/"Members Left". It appears that failcount only increments on a failure, but not on a transition imposed by someone manually puttintg  a node into standby.



I am just trying to figure out a way to trigger an alarm for Nagios any time resources get moved between nodes, so the cause can be investigated.



Any ideas?



Thanks,

Keith
