Weird problem with check_nrpe

Nagios Nagios Plugins support
1

hi

i installed nagios and it was working fine but after i upgraded when i’m getting this on the web interface

[blockquote]CPU Load

OK 	08-01-2008 01:36:18 	0d 18h 19m 2s 	1/4 	NRPE v2.5.1 [/blockquote]

So instead of giving the actual load i’m getting NRPE version and the same for other checks like check_http

I’m sure i did a silly mistake but i can’t seems to catch , your help is greatly appreciated
Thanks

Hi!

all I can say is that the message you get is the standard message when “testing” NRPE with a command without arguments, like “check_nrpe -H host”…
meaning that somewhere, your arguments are missing.

Hope this helps a little bit :slight_smile:

Yea exactly something is missing somewhere and my question is what is it and where ? :smiley:

OK, lets start with CPU Load being as it is top o’ the list…
What’s the service object look like on the nagios server? Something like

define service{ use generic-service host_name remotehost service_description CPU Load check_command check_nrpe!check_load }
What’s the check_nrpe command object look like? Should be something like

define command{ command_name check_nrpe command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ }
What does the nrpe.cfg definition of the check command look like on the remote server? Something like

Also, have you seen the NRPE configuration pdf at nagios.sourceforge.net/docs/nrpe/NRPE.pdf?

Thanks man

Here is the CPU load

[blockquote]define service{
use local-service
hostgroup_name US Agents
service_description CPU Load
check_command check_nrpe!check_load
}[/blockquote]

and here is the check_nrpe
[blockquote]

‘check_nrpe’ command definition

define command{
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -t 300
}
[/blockquote]
Am i missing the -c here ?

and as for the check in nrpe.cfg it’s

[blockquote]command[check_load]=/usr/lib/nagios/plugins/check_load -w 15,10,5 -c 30,25,20[/blockquote]

yep, thats the problem… slide that -c $ARG1$ onto the end of the command object so that the check will pick up the check_load argument from the service object.

Great it was fixed , the problem is that the commads.cfg is the new one which i didn’t update at all.

Every thing is working fine now , man you’re a genius :smiley:
