Yes. I know about that agent and it was quite useful when I used heartbeat, a 
long time ago.

But I did not find it useful in corosync environments. So I created my own 
agent that provides all nescessary information for monitoring. Basically you 
only need the number of online nodes and the sum of all failure counters.

But the idea to integrate a SNMP Agent part into the crm_mon is interesting. 
But this is much more difficult than a simple perl subagent. But help is 
welcome. Funding also ;-)
