Custom variables inside of Commands

[mirann]

Hey folks,
We are looking to do integration with Pagerduty in Nagios XI, and we were hoping to make use of some already defined Free Variables. We have the integration working, but the custom variable doesn't seem to come through.

In our Service and Host Templates, we have defined '_env' in the Free Variables screen. We currently are able to use this field when sending email by calling it as %env% in the Notification Template.
I've tried afew different ways, but none of them seem to actually call the content of the variable, they just send the name.

An example of the code being used, the last bit is my concern. The rest works just fine.

Code: Select all

/usr/share/pdagent-integrations/bin/pd-nagios -n service -k $CONTACTPAGER$ -t "$NOTIFICATIONTYPE$" -f SERVICEDESC="$SERVICEDESC$" -f SERVICESTATE="$SERVICESTATE$" -f HOSTNAME="$HOSTNAME$" -f SERVICEOUTPUT="$SERVICEOUTPUT$" -f SERVINSTANCE="$env$"

Is it possible to call custom variables through the commands setup in CCM?

Hi,

Is it possible to call custom variables through the commands setup in CCM?

Yeah, this can be done, the naming convention will change depending on if it's a host or service object. Take a look at the following guide for a detailed explanation ( see page 8).

So, if your free available is named _myvar, and it's a host object, you would actually reference $_HOSTMYVAR$.

The Nagios Core doc is pretty helpful here as well.

Let me know if you get it going or if you need more assistance.

Thanks for the info. I've made the changes as described, but still not getting the expected results.
The variable I'm trying to get "_env" is defined in a Host Template only.
I'm able to get this variable to output into email using this setup in the Notification window.

I have the PagerDuty commands set like this:

But the output to PagerDuty shows up like this:

Any thoughts?

Hi,

The other case is for passing values into those notification templates in Nagios XI that are used by PHPmailer. For the case of Pager Duty, you can drop the usage of notification variables %myvariable%and pass the system level macro to the command $_HOSTENV$ instead. In this case, you'll be using the custom variable as a macro.

Let us know if that works now.

That did it. I could have sworn I tried that variation, but I guess not.
Thanks for your help!
