[ClusterLabs] resource monitor logging

[Christopher Pax]

I am running postgresql as a resource in corosync. and there is a monitor
process that kicks off every few seconds to see if postgresql is alive (it
runs a select now()). My immediate concern is that it is generating alot of
logs in auth.log, and I am wondering of this is normal behavior? Is there a
way to silence this?
