If you're commenting out a line that has a non-printable character in it, then that does explain it.

Oh, sorry, I should have been clear. I comment out the new definition, which is at the bottom. when I try and restart the deamon it complains about line 1. which is far from the bottom.

For fun, try this:

Code: Select all

strings clientone.cfg > clientone_new.cfg
mv clientone.cfg clientone.cfg.sav
mv clientone_new.cfg clientone.cfg

See if it passes the sanity check

Nope. You can't have a "command_line" in a service check.

The service check definition uses "check_command" to specify the command and arguments.
"check_command" is defined in commands.cfg
The commands.cfg has a list of what FILE to execute when the COMMAND is given, and passes the ARGUMENTS to it.

You will want to look at http://nagios.sourceforge.net/docs/3_0/ ... ml#service for details.

I shall have a look.

Lots of problems in this file:

You have no closing "}" for the first definition.
You have no closing "}" for the second definition.
You use "command_name" in the last definition - should be "check_command"
In the same one, "check_disk!/" is not a valid check_command. I assume it should be "check_local_disk" if it's the machine that's running Nagios, or else you'll need to use an NRPE command here.

Fixing these got it to parse properly on my server.

Hi

The missing brackets } are do to some commands that i ran earlier from this forum.

I think we may be one to something with the nrpe commands. by chance do you know the nrpe command for checking disk?
I tried finding it but I have not had any luck.

To get NRPE working to check disks on a remote host, you need to edit "/usr/local/nagios/etc/nrpe/common.cfg" to make sure that this line is in there somewhere:

Code: Select all

command[check_disk]=/usr/local/nagios/libexec/check_disk $ARG1$

Then on your Nagios host, edit /usr/local/nagios/etc/commands.cfg (or wherever it lives) to make sure you have a check_nrpe command:

Code: Select all

define command{
        command_name    check_nrpe
        command_line    $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$ -a "$ARG2$"
}

Then you can make a service check that uses check_nrpe command on the Nagios host to use NRPE to execute the check_disk command on the remote host with the appropriate parameters:

Code: Select all

define service{
        use                     nrpe-service
        service_description     Root Partition
        hostgroups              private
        servicegroups           System
        check_command           check_nrpe!check_disk!-w 20% -c 10% -p /
}

(Note that we use hostgroups to specify what services should be checked on each machine. Use an appropriate "host_name XXX" command for your configuration.)

Does that help?

i386, did eloyd's post help you at all?
