There was one which I was using for a while - https://github.com/rodneymo/rig-monitor but it was unstable - would crash every now and then and wasn't doing everything I wanted. Hence I wrote my own code and shared it on Github.
I used PowerShell, SQL Server and Grafana. All of these can also be installed on a 64bit Linux today. And all of these are FREE software. I have good experience with SQL server and hence went this route. It took me one day to write this code and does exactly everything I wanted the way I wanted it
