Service Command Issue [CENTOS 5.4 NAGIOS 3.2.1]


First and foremost I am new to Nagios and my Linux skills are rusty.

I have Nagios installed and working. I’ve defined a number of hosts groups and have it monitoring our servers/switches/routers successfully. However, when I click on a warning and try to issue a service command i get the following error.

Error: Could not stat() command file '/usr/local/nagios/var/rw/nagios.cmd'! The external command file may be missing, Nagios may not be running, and/or Nagios may not be checking external commands. An error occurred while attempting to commit your command for processing.

I’ve searched all over looking for a solution, but none have worked. The latest solution I tried can be found here

Please help!

[root@TLC-NAGIOS nagios]# id nagios uid=500(nagios) gid=500(nagios) groups=500(nagios),502(nagiocmd) context=root:system_r:unconfined_t:SystemLow-SystemHigh

Thanks in advance and let me know if you need to see any of my config files.


did you install an RPM or from source?
if from source you probably missed “make install-commandmode”.


I already ran that, same error. However, I didn’t run it until after I started configuring Nagios and stumbled across it on my search.

Here is the guide I followed
