Monitoring is essential for IT teams, but traditional alert methods like email or SMS can be slow, cluttered, or costly. If you use Telegram, you can get your Checkmk notifications delivered instantly and directly to your phone or desktop — no middlemen.
In this post, I introduce a lightweight, robust Telegram notification script I developed. It integrates seamlessly with Checkmk and ensures you never miss a critical alert again.
Why Use Telegram for Monitoring Alerts?
Telegram offers clear advantages:
- Instant push notifications — no mail servers or SMS gateways required
- Cross-platform support — desktop, mobile, and web clients
- Secure communication — end-to-end encryption
- Free and ad-free
- Simple Bot API for automation
This makes Telegram an ideal choice for IT teams and sysadmins who need to react quickly.

The script is designed as a lightweight solution:
- Compatible with Checkmk version X.Y and above

It elevates your monitoring alerting to the next level.
