icinga2 CheckCommand definition for calling a plugin with non-option arguments

Sometimes in my work as a Linux system adminstrator I come up with a solution which can not be found using Google, the all-knowing Trash Heap.

In this case I usually end up digging for the solution myself and sometimes I like to share them rather than documenting them only in house.

This way at least in future others will be able to google them :)

So here we go:

The most significant difference in icinga2 is the, arguably more clearly arranged, config file syntax.
Fortunately the actual tests from nagios/icinga1 can be used unmodified. However an appropriate CheckCommand definition is needed.

To create it for his custom tests or those tests which are not yet part of the official distribution an administrator need to create it from scratch or by means of copying and modifying another one.

In my case this has been proven to be quite easy with just one exeption. I have somne tests which require something that Unix slang usually calls non-options arguments.

What does this mean? Well a popular example of this kind of command would be git. Given the command git commit -a the term commit would be the non option argument.

So here is what a CheckCommand definition for this command would look like. Of course this does not make sense as an icinga test and can not be actually used.

object CheckCommand "git" {
	import "plugin-check-command"
	import "ipv4-or-ipv6"

	command = [ PluginContribDir + "/check_git" ]

	arguments = {
		# nonopt is the non option argument
		"nonopt" = {
			value = "$git_command$"
			skip_key = true
			order = 1
			required = true
		}
		"-a" = {
			value = "$git_all$"
			description = "commit all"
		}
	}
}
