Error: "NRPE: Unableto read output"<o:p></o:p> </div> <o:p> </o:p> I'm a bit confused about how exactly to add stuff with NRPE to monitor local services on my remote hosts. I got the basics out of the way and I can already monitor the easy stuff like users, procs, swap etc. More ambitiously, I wanted to monitor the status of my "pbs_mom" (Torque Scheduler daemon) on each node in my cluster. I found the script check_pbsmom.sh on the NagiosExchange (snippet below) and copied it to my /usr/local/nagios/libexec. Then I added this line to my nrpe.cfg command[check_pbsmom]=/usr/local/nagios/libexec/check_pbsmom But then I don't seem to have much success. remotehost>/usr/local/nagios/libexec/check_nrpe -H localhost -c check_pbsmom NRPE: Unable to read output If I just run the shell script though it seems to be working /usr/local/nagios/libexec/check_pbsmom.sh PBS_MOM OK: Daemon is running. Host is listening. What am I doing wrong here! I'm still a bit confused about the interaction between command.cfg on the monitoring machine and the nrpe.cfg on the remote host.
