OK, maybe someone wants to add that statement to the corresponding manual

The crm_mon as I know it, seems to periodically output the clusters state, and
I always felt it's just doing sleeps between polling the state.

BTW: When I enter "man crm_mon", I get:
PACEMAKER(8)            System Administration Utilities          

       Pacemaker - Part of the Pacemaker cluster resource manager

       crm_mon mode [options]
Isn't "NAME" completely off? If I compare it to "man ls", I get:
       ls - list directory contents

As the NAME is used for "man -k", you get nothing when running "man -k monitor
|grep crm".
