Array variable from service to command argument

Service Monitoring
1

I have a service that defines some values for a command. The command executes a script, and the arguments are formatted as --argument=value. In my service, I define as vars.variable = [ "something" , "something_else" ].This argument is meant to be defined multiple times. I have set skip_key = true and repeat_key = true, but if I set value = "--argument=$variable$" I get the error " Error: Mixing both strings and non-strings in macros is not allowed." I’ve also tried value = "--argument=" + "$variable$".to_string() as well, to no avail. I’m admittedly new to Icinga so any direction on this would be appreciated. Thanks.

you would need something like:

vars.variable = [ "something" , "something_else" ]

  arguments = {
    "--argument" = {
      value = "$variable$"
      description = "..."
      repeat_key = true
    }
  }

https://icinga.com/docs/icinga-2/latest/doc/03-monitoring-basics/#command-arguments-repeat-key

from the docs:

COMMAND ARGUMENTS: REPEAT KEY ¶
Parameters can use Array as value type. Whenever Icinga encounters an array, it repeats the parameter key and each value element by default.

  command = [ NscpPath + "\\nscp.exe", "client" ]

  arguments = {
    "-a" = {
      value = "$nscp_arguments$"
      description = "..."
      repeat_key = true
    }
  }

On a host/service object, specify the nscp_arguments custom variable as an array.

  vars.nscp_arguments = [ "exclude=sppsvc", "exclude=ShellHWDetection" ]

This translates into the following command line:

nscp.exe 'client' '-a' 'exclude=sppsvc' '-a' 'exclude=ShellHWDetection'
