Send dynamic parameter to NRPE command

[codrinh]

Hello all,

Please advise if the below scenario is possible, currently I'm looking at the documentation and I could not find an example for this.


Nagios server is sending a 'dynamic value' in the pipe to the nrpe agent, but the value is not hard-coded in the .cfg files (checks type - active, every minute)

service.cfg

Code: Select all

check_command           check_nrpe!custom_check!!!!!!!

nrpe receives (e.g:) :

Code: Select all

custom_check(String dynamic_value)

What is the source of truth for the dynamic value?

Nagios Core offers some "standard" and "custom" macros you can use in your object definitions, but they may not be a good fit for your use case:

Thank you for the reply Matt.
I was looking into the macros and this is the approach that we will have to use.

I have another question regarding the Nagios plugins

From the Nagios Core Plugin API
Plugins may also return optional performance data that can be processed by external applications.

I would like to perform the following flow:

• deploy the NRPE agent
  add custom script & custom command in NRPE
  Nagios server will trigger the check_nrpe!custom_command
  custom_command returns `exit_code|exit_message|performance_data`
  capture the `performance_data` at server side ( no mater of the status code )

Is this doable with event handlers ? If not, is there a way to achieve this ?

Regards.
