Hi,
i got a small issue with the CLusterMon agent. The monitor actions for this
agent seem to fail (if i look into syslog, you'll find it below) and i am not
able to troubleshoot it. I tried to start the agent on the failed node by hand
but it don't see startup / status errors. The ClusterMon seems to fail only on
the passive node, therefore i thought it should be a problem caused by missing
www directories or something else but i cannot see the error.

Expects to have a fully populated OCF RA-compliant environment set.

I can see that CLusterMon is started and even the html output works but there
is still this error.
