Re: [Nagios-users] check_procs returning wrong data
I finally got it working but it was not that easy. As I am using CentOS 5, by default the requiretty value in the /etc/sudoers file is activated, so I had to edit it like this: #Defaultsrequiretty nagios ALL=(ALL) NOPASSWD:/usr/local/nagios/libexec/check_procs And the command in the .cfg file would be like this: command[check_total_procs]=sudo /usr/local/nagios/libexec/check_procs -w 150 -c 200 Hope it helps!! 2012/6/18 Andreas Ericsson a...@op5.se On 06/18/2012 11:51 AM, Axel Amigo Arnold wrote: Hi Andreas, thank you for the response.

Re: [Nagios-users] Help with DISK UNKNOWN - free space: error
Solved!
Just changed
command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10%
-p /dev/root
to:
command[check_hda1]=/usr/local/nagios/libexec/check_disk -w 20% -c 10% -p /
nagios user has problems to access to /var/named/chroot/var/run/dbus but
now works well.

Check the permissions on the remote server, eg can the NRPE User run the
command locally.

Re: [Nagios-users] Help with DISK UNKNOWN - free space: error
Check in /var/log/messages (or wherever you are logging to) on the server that
should be running check_hda1 to ensure that the nagios node is able to
communicate via nrpe.
Also check you can run /usr/local/nagios/libexec/check_disk -w 20% -c 10% -p
/dev/root on the nrpe node.
Is it owned by the nagios user, does it belong to the nagios group (or
whatever you’ve defined for this in nrpe.cfg)

Deborah
