NRPE not returning status info

[jeremy.garman]

I have several Windows 2008 servers running the latest NSClient++ agent, and they are all working fine, and displaying metric-related info in the Status Information column of the Nagios server Services view.
I have several other servers, these are RHEL 6.2, running the latest NRPE agent, and they are all working fine (and tested by failing client-monitored services, and have a corresponding Critical alert generated by Nagios), but none of them display any info at all in the Status Information column of the Nagios server Services view, only the NRPE agent version. I've double checked my host and service configurations with all the templates that I used, and checked with online host and service definition examples, and they seem fine... and yet, no Status Information data. What's up with that? I've attached a screen shot of what I see on the Nagios console. Below are examples of host and service definitions for RHEL 6.2 servers for which no Status Information is displayed. Any ideas?

define host{
use linux-server
host_name lmprodwa1.lmgroup.com
alias lmprodwa1
address 192.168.115.69
}

define service{
use generic-service
host_name lmprodwb3.lmgroup.com
service_description CPU Load
check_command check_nrpe!check_load
}

Hi jeremy.garman,

I would recommend checking your commands.cfg and make sure it includes the -c before $ARG1$, as show below:

Code: Select all

define command {
       command_name     check_nrpe
       command_line     /usr/local/nagios/libexec/check_nrpe -H $HOSTADDRESS$ -t 30 -c $ARG1$
}

Also check from the command line that it works:

Code: Select all

./check_nrpe -H host.domain -c check_load
OK - load average: 0.00, 0.05, 0.02|load1=0.000;15.000;30.000;0; load5=0.050;10.000;25.000;0; load15=0.020;5.000;20.000;0; 

I've noticed that missing the "-c" in the command but including the check_load only returns the NRPE version number.

Hope this helps.

Kind Regards,
