I'm tagging as an enhancement, I'm not currently sure of any timeframe when we could start looking at this. I can say based on where we are with the beta (v3.x) that this will only be implemented in v3 as v2 is already in a feature freeze state.

This would really help when choosing between Application Insight and ie. Sentry.io which already collects this information

This seems to be very useful information for AppInsights to collect. It would make a great feature.
