check_by_ssh always returning OK

[Jason Dixon]

If I could, I'd like to suggest a few plugins I recently completed and
uploaded as patches to the sourceforge site.  One of them is OpenBSD/PF
specific, so I won't mention it here.

The other two are check_cpu and check_df.  Both connect via ssh, but the
check is actually performed on the output, not the success/failure of
the ssh connection.  Check_cpu, for example, gathers/checks cpu load
averages.  Check_df gathers df output and checks the free percentage.

The advantage over some of the other plugins is that they don't require
monitoring facilities *on* the target machine.  Rather, they use the
native 'w' and 'df' utilities.  Obviously, this is only relevant to *NIX
boxen.

Hope these are of some remote use to others, as they have been to me.

Even when the remote plugin exits with an error code other than 0, nagios shows OK leading me to believe that check_by_ssh is returning error code 0 regardless. I am using 1.3 beta 1 of the plugins and nagios 1.0b6. Why is this happening and how do I fix it? Thanks.
