Any metrics around errors?

[findchris]

Hi there.

Reading through the metrics section of the README, I noticed there were no metrics around errors. Surely there are error conditions in Koupler, such as with issues writing to a stream (I suppose throttling is a separate concern), and having error metrics exposes a method for monitoring the health of what's happening within Koupler.

Since this metric is not currently instrumented, how do you (or any other users of Koupler) ensure the health of Koupler, other than a basic monit entry?

I appreciate your time and feedback.

One example could be the EventQueueFullException, and this error handling block. Don't see too many other places where such instrumentation might go.

Great idea @findchris. We have log scraping in place to alert on errors, but I would love to see metrics for it instead.
