How to tracking code coverage / unit test related metric over time? Historical chart? Follow

Hi, I'm using ReSharper intensively a 20 years old .NET project (yes it started with version 1.0) and I would like to "track" somehow the project on the code coverage or number of tests or some metric related to UnitTest. 

I can't find anything build-in (maybe I've missi it?) or is there any tools/project people used to keep lets say a daily snapshot on how that goes.

I know that code coverage is not "THE" metric to keep track, but it's something I looking as a personals motivator.
