Populate free variables

[hales8181]

Is it possible for a check to populate a hosts free variables? i.e a check pull back the latest software version for instance and populate the hosts free variable for the software version.

Not exactly. One way to do that sort of thing would be to leverage the back-end API of Nagios XI. Documentation regarding usage of the back-end API can be found in the "Help" section of your Nagios XI installation.

The gist of the API calls in script form might look like:

• Get the current host object you want to check the software version of
• Delete it (because updates aren't implemented yet, we start fresh using the previously grabbed copy)
• Get the software version from whatever remote system
• Add it to your host object, maybe under something like _softwareversion
• Re-create the host

This would result in the changes being "staged" and ready for your next apply config. You could also alter the last call you make to include applyconfig=1 to apply the changes right away.
