Monitor Fileserver

[Josh]

Hans / Ryan,

Thanks for your input...

I thought the question might arise about "why don't I
monitor the server housing the shares"... well, the
problem there is the machine is a NetApp device (not
running windows and won't allow me to install anything
on it of course... it's an appliance).

I've tried touching the /root/.smb/smb.conf...  the
problem is most likely related to the nagios user
can't even see inside /root.

I like your idea of mapping the drives under the
nagios user and then running the service as the nagios
user... I'll give that a shot.

On a side note, I did try getting the nrpe checks to
work on the windows server but am getting the
following error:

"CScript Error: Execution of the Windows Script Host
failed. (Catastrophic failure)"

A little research shows it is most likely related to a
software security policy in place.  Anyone on this
list know what I need to change?

Thanks again for all your help.

Josh
