Ah, the system internal tools is one thing I really miss after switching to Linux on all my pcs. This port would be so awesome

Azure Insights provides similar kind of information.

Maybe that is where the porting effort went.

Could well be. If I recall correctly the motivation behind the porting was to give their engineers a unified set of tooling for troubleshooting windows and Linux (on Azure). I just assumed that the porting efforts would result in a similar set of tools to use locally on the box.
