Can you run the following command and post the output?

Code: Select all

grep nrpe /usr/local/nagios/etc/commands.cfg

I know you mentioned you're doing a new install - is there a reason you've chosen an older version of ubuntu AND nagios? I noticed in the screen shot you're on 3.x.

Our newest version is 4.1.1

This should work to fix it though, you will need to modify /usr/local/nagios/etc/commands.cfg and add this to the end -

Code: Select all

define command {
       command_name                             check_nrpe
       command_line                             $USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 -c $ARG1$ $ARG2$
}
Just to clarify as well - you posted this in the Nagios XI forum. Are you actually using Nagios Core?

Sorry I was not sure which product we were using. I am not in a new install did not mean to confuse you. I took over for someone and I do not have as much Linux (Ubuntu) experience as the previous person. So this is all running on old OS and tools. They also did not put things in the same places you have asked me to look at so this has been fun in that I am getting experience but frustrating in that I need to clean this up to have standard setups so if I get hit by a bus the next will have an easier time. Thanks for the help!

Try this command: find / -name commands.cfg -exec cat {} \;

Please post the full output of that command, if there are password or something you don't want us to see in there, please edit them out before posting.

Thanks!

Are you still receiving the same error?

Yes, I tried putting in the code you posted to the second command.cfg file and I could not restart Nagios if kept error out on that config file.

Code: Select all

define command {
       command_name                             check_nrpe
       command_line                             $USER1$/check_nrpe -H $HOSTADDRESS$ -t 30 -c $ARG1$ $ARG2$

What is the result if you run the command over the CLI?

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H LYNCFE2 -c CheckMem -a MaxWarn=80% MaxCrit=90% ShowAll type=physical
(you may need to change LYNCFE2 to the IP)
