So, I took a first shot at writing an external-agent script that would 
somehow reproduce the behavior of crm_mon when SNMP support is built-in.

Basically, to refocus the discussion, I've written this script because I 
want to be alerted via SNMP on most of the cluster events but sadly my 
version of crm_mon doesn't have SNMP support (RHEL6), so I cannot use 
this feature combined with ocf:pacemaker:ClusterMon but I can use 
crm_mon ability to trigger an external-agent (script, binary...)

Script: http://files.floriancrouzat.net/clusterMon.sh
It respects PCMK-MIB.txt.

ps: yes I know, lots of comments and few actual lines of code but that's 
just because 
http://clusterlabs.org/doc/en-US/Pacemaker/1.1/html-single/Pacemaker_Explained/#ch-notification 
hasn't been published yet.

Any directions, hints or corrections are welcome.

Florian.
