Yes. crm_mon -S i think, read man crm_mon.

ClusterMon uses crm_mon.

There are developements for a openais SNMP agent on the way. See the mail of  
sato yuki of May, 5th. You also can try heartbeat's SNMP subagent, although it 
is still in some testing for openais.

I am checking the failcounter from my NMS. So in any case a node dies I get at 
least one trap and an error on the failcounters. Pretty straight forward on 
the NMS. And by the way: I am using Zabbix.

Greetings,
