Event Notification and Correlation Center?

Question

System administration

I have several different monitoring systems, some are self-written, some are munin - all systems can call an external command in case of problems.
Now, when there are problems, they all send an email, but if the disk crashes and the check goes on every 5 minutes, then I will receive an email every 5 minutes.
I don’t want (can’t) change all systems to one big and good one (zabbix) because of labor costs. Maybe someone saw a script (daemon, service) to the input of which all events are transmitted, notification rules are configured.
I would like the administrator to receive not 60 letters per hour (if the check is every minute), but the first letter, then another letter after 20 minutes, then another letter after an hour, then a letter after 4 hours.

Answer 1

That doesn't happen. “I don’t want to do it, but I want it to be cool!”
