[ubuntu] Nagios - NRPE: Command 'check_sda1' not defined

[JRA]

Hi all - hope this is in the right section, might also do in the network management bit...

 

Anyways, reinstalled Ubuntu server on an old server, uses HP hardware raid so root is on /dev/cciss/c0d0p1. Use nagios here which now gripes as per the title, but, well, yeah there is no /sda1 so that's kinda right, however nagios I don't want you to look for /sda1 I want you to look at /dev/cciss/c0d0p1!

 

Anyone know how to steer it right? I have a feeling I'll need a plugin of some sort on the client to tweak the output to say /dev/sda1 is really /dev/cciss/c0d0p1 but idk.

 

Thanks in advance for any bones thrown!

Looks to me like some config file is referring to a check that is not defined - probably in command.cfg . I'd nip into the config path (possibly /usr/local/nagios/etc) and

 

grep -R check_sda1 *

 

and see what that says.

Thanks, that got me to it - hadn't defined check_sda1 in /etc/nagios/nrpe.cfg on that host, added in:

 

command[check_sda1]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /dev/cciss/c0d0p1

 

and now all is well.

Hi,

 

I think there is a more generic check_root command which may help. You may not need to know the name of th drive.

 

Ta,
