Hi Guys.

I need to know if it's possible to pass a plugin option like "-w" or "-c" throuth nrpe like Argument.

I mean:

I have the next command definition: $USER1$/check_nrpe -H $ARG1$ $ARG2$ $ARG3$ $ARG4$ $ARG5$ $ARG6$
/check_nrpe -H x.x.x.x -c check_disk -w 20% -c 30% -p /

and it's call to the next client command: command[check_arg]=/usr/local/nagios/libexec/$ARG1$ $ARG2$ $ARG3$ $ARG4$ $ARG5$ $ARG6$

There is any way to get some thing like this?

Thanks a lot.

This should not be an issue.

On your remote client, we will have to modify the nrpe.cfg file to allow argument passing. Please note that enabling this option will make NRPE less secure.

Code: Select all

vi /usr/local/nagios/etc/nrpe.cfg

Change:

Code: Select all

dont_blame_nrpe=0

to:

Code: Select all

dont_blame_nrpe=1

Restart xinetd:

Code: Select all

service xinetd restart

From your Nagios host, you will now be able to pass command line arguments as follows:

Code: Select all

/usr/local/nagios/libexec/check_nrpe -H x.x.x.x -c check_disk -a '-w 20% -c 50% -p /'

Let me know if this helps - thanks!

While not particularly safe, it's likely possible:

nrpe.cfg

Code: Select all

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

Code: Select all

[jdalrymple@localhost libexec]$ ./check_nrpe -H 127.0.0.1 -c check_arbitrary -a 'check_dummy 0'
OK
[jdalrymple@localhost libexec]$ ./check_nrpe -H 127.0.0.1 -c check_arbitrary -a '../../../../bin/ls'
