Pushover is a simple service to send messages from various sources to Apple or Android mobile devices, where they appear as notifications. On the desktop, the messages can be received via the browser. The connection is established via two API keys for a group and an app/source.
In Pushover you need to create both a group, even if you only have one 'group', and an app explicitly for Checkmk — each receives their own API key:
Create a new group with at least one member via Create a Group in Pushover.
Copy the displayed Group API key.
Create an app with any name via Create an Application/API Token.
Copy the displayed App API key.
In Checkmk it is generally sufficient to specify the two keys: . For the Notification Method choose the item Push Notifications (using Pushover). . Specify the App-API key under API Key. . Specify the Group API Key in User/Group Key.
You can optionally activate the Priority and Select sound pushover functions. You can use the priority function to override rest periods configured in Pushover — and then accompany such alarms with appropriate sounds.
For testing you can use the Fake check results and Custom notification commands.
