Searching the archives turns up a few other people reporting the same problem, but I can't find a solution. I am trying to use check_by_ssh to run the check_disk plugin on a few remote systems. When I run this from the command line, it always does the right thing. It returns the correct string and return code (checked with 'echo $?'). It works flawlessly. However, when this is set up to run through Nagios, it usually reports the check in the UNKNOWN state...even though it still gives the correct "OK..." string. Occasionally, Nagios will change it to OK or WARNING or whatever is correct at the time, but for a good 90% of the time, it just sits there in UNKNOWN. It doesn't seem to matter if the target machine is Linux or Solaris, nor can I find any pattern to when and where it happens. Again, it *always* works perfectly when run from the command line. I've played with giving check_by_ssh a hostname instead of an IP address. I've tried it both with '-l nagios' and without (it's always run from nagios account). I've also tried the -f flag (the purpose of which I don't really understand). Nothing seems to help. For the time being, I'm just running an SNMP client to get this info into Nagios, but I'd really rather use check_by_ssh if at all possible. Has anyone else seen this problem and/or found the cause of it? Here's the exact command I'm using on the command line. This same thing is configutred in my .cfg file. check_by_ssh -H 192.168.230.112 -C '/home/utils/nagios/libexec/check_disk -w 10% -c 5% -p /var' Thanks!<o:p></o:p> </div> </body> </html>
