rabbitmq-server upgrade failed, but Core still works?

Good afternoon, all!

I ran some updates on my Nagios server yesterday (Ubuntu 14.04 LTS) and apparently broke rabbitmq. The crash dump and apt logs aren't very helpful, but they're available. The odd thing is that Core is behaving just as it has since the original installation. ???

So, a couple of questions: first, how does Nagios use rabbitmq? Is there a default config and setup for rabbitmq in Nagios? This is if I can delete and reinstall rabbitmq for Nagios. Second, if rabbitmq stays broke, what part of Nagios would I have trouble implementing? If I want to start monitoring some other aspect of my datacenter, what part of Nagios would fail because of rabbitmq not loading?

Thanks to all for looking?

Gregg

It doesn't unless you're working with some sort of custom installation.

I'm assuming you might have some sort of custom notification handler configured that makes use of RabbitMQ?

Did a deep-dive into the rabbitmq configs - I don't see where it connects to anything. If it doesn't affect Nagios, I'm OK with leaving it alone.

Thanks!

@mcapra is correct, we don't rely on RabbitMQ for anything in Core and we don't (to my knowledge) maintain any code that does (except maybe some plugins for monitoring it).
