Cronjobs are a great feature of applications of any size. They allow all kinds of stuff: imports, exports, background processing, etc. But managing cronjobs can be hard. Some common problems developers encounter when trying to manage cronjobs:

- The environment is different. Paths and executables may be different and not available.
- It is possible that cronjobs overlap and bring your server to it's knees.
- What about output? How to handle that?

Jenkins is most known for it's Continuous Integration capabilities. But did you know you can also use it to execute other tasks? It's a great fit to manage your cronjobs. Only need an e-mail when an task fails? It's just configuration! You want to check the queue size on your clients server? Build a mysql query and execute it.

It gives you a great flexibility over managing your cronjobs.
