Monitoring with Dashing

This is a side project I’ve been working on for several months now.

Part of our daily routine at work involves monitoring the different systems ensuring our data center runs smoothly. This ranges from finding out whether every server is getting enough power, drawing too much power, to whether it’s even running at all.
