If you use Zammad as your IT service desk, you probably also have a monitoring tool in use. Several such tools can be integrated into Zammad - including Monit.
Monit has been successful in this area for quite some time and is especially convincing due to its quick and easy setup. Just like Zammad, Monit is open-source and relies on simple design and a strong community.

The Monit integration with Zammad allows for automatic ticket creation for every email you receive from Monit. This way you have everything in one place and never lose track of any issues or to-dos.

Features of the Monit integration in Zammad:
- Automatic ticket creation through emails from Monit
- Automatic ticket closure (on Recover) through emails from Monit
- Configuration/integration via the Zammad admin interface (Integrations → Monit)
