Check remote docker container status

I have an Icinga2 server and I’m trying to use this[1] plugin, but when I try to check containers from remote, I get an error as follows. It 's running when try on the remote server. Monitor server appears as Check Source.

[1] GitHub - BlackZork/check_docker_container: A simple nagios/icinga2 plugin for checking docker containter state

## Plugin Output
usage: check_docker_container [-h] -n NAME
check_docker_container: error: the following arguments are required: -n/--name

My conf:

apply Service " {
  import "generic-service"
  check_command = "docker_container"
  vars.docker_containers = [
  assign where == ""

Could you share the command object docker_container?
