Collector has not reported any metrics / Deleting a collector

Hello everyone,

I have a collector that came up with this error today “Collector has not reported any metrics in ### minutes”. I believe it to be a communication issue but need to find the logs to prove it, what should I be looking for in the logs? and what’s the name of the log to look at? If I’m off base on this assumption please let me know.

Also, It has a couple of “non-working” event sources attached to it, if I were to delete it I’m assuming the event sources associated to it would intern be deleted as well?

Thanks and have a great day,
