Nagios Support Forum

Red Hat Enterprise Linux Server release 6.2 (Santiago)
64bit
Manual Install

Hello,

External commands has stopped working suddenly, without to change anything.

System component status have some components down (see attach), and pnp graphs are not drawing. I suspect it could be a permission issue, but apparently all permissions are correct...

And it seems nagios is seeing commands and services up...

Is crond running? If it is stopped that may be the problem

No, it is running...

service crond status
crond (pid 2104) is running...

Lets try to restart it. Also, lets tail the cron log

tail -f /var/log/cron

Additionally, can you post the output of

Here the cron log:
