Not so fast :-)
crm_mon supports
-E, --external-agent=value
A program to run when resource operations take place.
-e, --external-recipient=value A recipient for your program
(assuming you want the program to send something to someone).
so without recompiling, you can call a script - possibly it could call
something that sends out snmp alerts ;-)
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.
Is that something you'd like to include with pacemaker?
Well, I'm really not sure it would be useful for anyone as it not generic at
all, and highly oriented for my needs.
Looks pretty configurable to me.
Maybe it would fit better in an "example" section of Pacemaker_Explained
That also works :)
Well, do as you please. I'm by no means able to choose :)
Not sure what you meant by "Is that something you'd like to include with
pacemaker?" but feel free to commit the script to any "extra" or
"script" folder in pacemaker sources, maybe remove my name and add the
required license(s) to it or just paste the few bash lines I produced to
the correct section of the correct documentation.
I did some polishing on the comments in the scripts since Chapter 7 of
Pacemaker Explained has been published
(http://clusterlabs.org/doc/en-US/Pacemaker/1.1-crmsh/html/Pacemaker_Explained/s-notification-external.html)
