[ubuntu] nagios malfunction

[RabbieBurns]

OVer the weekend nagios has decided that all my linux boxes have a root partition drive space warning, all of them are reporting

DISK WARNING - free space: / 2006 MB (11% inode=83%):

 

But this is not the case and they are all fine..

 

What could have caused this and how can I fix it?

[RabbieBurns]

IVe disabled notifications for that service on them all for now, but any idea how to sort this would be a great help

[RabbieBurns]

hmm seems there was an 11gb mail.info in /var/log on the nagios box, which was causing a warning for nagios..

 

Not sure why it would report for all the linux boxes.. time to check the configuration

[RabbieBurns]

Ok, it seems that whats happening is that for all my linux boxes, what is being reported for them all matches the nagios box.

 

Cant believe I hadnt noticed this before..

 

For all of them I have

define service{
       use                             local-service ... 

 

Should that only be local-service for the nagios box? What would it be for the other linux boxes?

[RabbieBurns]

OK I think Ive found the problem.

 

I had used the localhost.cfg as a template for all the other boxes.

 

Ive had to download and install the nrpe daemon on the remote boxes and the plugins on the nagios box.

 

Now as soon as I can figure out the firewall/hosts.allow or whatever it is stopping me from connecting, I think it should be sorted.

[RabbieBurns]

OK Ive opened the firewall, and can now get a reply

 

root@nagios:~# /usr/local/nagios/libexec/check_nrpe -H 10.1.1.12 
NRPE v2.12

 

But Im still getting a plugin not found..

 

What should a) my server.cfg look like with regards to the commands

b) the commands.cfg look like with regards to the nrpe commands

c) should I need to define any services for nrpe ?

 

Im a bit stuck here

[RabbieBurns]

Ok. Managed to get it working.

 

Had to define custom services and give the absolute path to the nrpe plugin

 

But its all good now.

 

Thanks for all the replies
