Monitoring Consumer groups processing using custom metrics

Nice Article nadavbh / yodobrin Thanks for this. I have one question what will be the difference between the throttling vs lag?

I actually created an alert based on throttling. I thought do I need to worry about the lag?  

Before answering this I'll give my actual use case to let you understand better. My producer in this case is Azure(Diagnostic logs) from all resources (let's say 1000 different azure resources). My Consumer is Azure Function (EventHub Trigger). Sometimes my throttling goes much and leads me to miss lots of (GBs) of events(diagnostic logs). Hence I created the alerts based on throttling. I'm wondering if is there any benefit for me to use these Lag metrics.
