module: logicmonitor
short_description: Manage your LogicMonitor account through Ansible Playbooks
description:
  - LogicMonitor is a hosted, full-stack, infrastructure monitoring platform.
  - This module manages hosts, host groups, and collectors within your LogicMonitor account.
version_added: "2.2"
author: [Ethan Culler-Mayeno (@ethanculler), Jeff Wozniak (@woz5999)]
notes:
  - You must have an existing LogicMonitor account for this module to function.
requirements: ["An existing LogicMonitor account", "Linux"]
options:
  target:
    description:
      - The type of LogicMonitor object you wish to manage.
      - "Collector: Perform actions on a LogicMonitor collector."
      - NOTE You should use Ansible service modules such as M(service) or M(supervisorctl) for managing the Collector 'logicmonitor-agent' and 'logicmonitor-watchdog' services. Specifically, you'll probably want to start these services after a Collector add and stop these services before a Collector remove.
      - "Host: Perform actions on a host device."
      - "Hostgroup: Perform actions on a LogicMonitor host group."
      - NOTE Host and Hostgroup tasks should always be performed via local_action. There are no benefits to running these tasks on the remote host and doing so will typically cause problems.
