agents: linux
catalog: unsorted
license: GPL
distribution: check_mk
description:
 Tested with Mailcow versions 2022-07a and higher (use at your own risk with lower versions).
 Tested only with fully dockerized Mailcow instances.
 You have to provide at least the hostname/IP of your Mailcow server and an API key.
 Got to configuration settings and create a new API key (read-only access is sufficient).
 Allow API access to at least your CheckMK server IP address.
 Shows several information about a Mailcow instance, e.g. number of domains/mailboxes/messages.
 The check will raise WARN/CRIT if the number of domains is above the configurable levels.
 The check will raise WARN/CRIT if the number of mailboxes is above the configurable levels.
 The check will raise WARN/CRIT if the number of messages is above the configurable levels.
