NodeJS Event Loop Monitoring

This utility library aims to monitor the event loop and report any lags above a certain threshold to a consumer. It is using heavy to monitor the event loop. It is also logging lags from time to time.

Use case

In my case, I'm using this utility because I've a lot of jobs spread accross consumers, those consumers need to manage what they can('t) do. When the event loop becomes laggy it means the single thread (event loop) is too heavily used and that space for I/O is lacking. Hence I'm registering a listener that breaks the parrallelism of the process.
