I'm trying to find a tool where you can easily monitor cronjobs for the company I work at. Rundeck seems like the perfect tool for this but I can't figure out if it's possible to integrate the existing cronjobs into Rundeck. It's too much work to do this manually because there are hundreds of them.
If you now another tool that can do this feel free to recommend!
I'd rather want it to be open source but if it's paid and it works correct I'm open to it.
Rundeck works as a "very enhanced cron replacement" maybe the best approach in your case is to migrate your cron jobs to Rundeck and use the notification for monitoring. This looks like a good starting point for you, don´t forget to visit the official documentation.
