Nagios: Enable external commands

“Here we are again, back witho ur old friend Nagios. If
you’ve been following you know I have covered quite a bit of
ground with this outstanding network monitoring tool (check all
Ghacks Nagios articles). There is a reason for this, Nagios is an
incredible tool. But for many of you, you might have come across an
error when attempting to run a few of the more powerful features.
This error happens when you attempt to use any of Nagios’
external commands. But what are these external commands? Nagios is
capable of running commands from external applications. This allows
Nagios to expand farther than it could otherwise.

“But when you see this error you know that your Nagios
installation isn’t able to use any external commands. Fear
not, this error is simple to over come, and in this article I am
going to walk you through the fix.”
