One of my favorite GitHub projects is the CheckMK Notification Module for Instant Messenger Telegram. For private use the CheckMK RAW or FREE Edition offers a great and cost neutral solution. One more reason to promote the development of additional modules and make them public. I am also pleased that although the project is still very young, some GitHub users have already made contributions to improve it.

What does the script do?

• A notification rule can be created directly in CheckMK after installation by copying it to a specific directory.
• Here, the Telegram API token, that must be created in advance via the BotFather and the group ID are configured and passed to the script by CheckMK directly.
• The script creates a formatted notification message and sends it to the Telegram service.
