A monitoring/configuration system for the various mixed Windows/Linux/MikroTik/Cisco environments I manage. It's absolutely re-inventing the wheel, but since I could just not find anything existing that really worked for me (heh!), I'm now dragging that particular millstone along as well.
It mostly connects to hosts over SSH, and uses CLI commands to gather data and make configuration changes as needed. Think things like NMVe storage health, disk space usage, Windows AD/Exchange/SQL/VSS health, Docker containers, reverse proxy mappings, Netflows hinting at BitTorrent or other data exfiltration, finding a MAC on a port, configuring VLAN access for a port/trunk, Wireguard tunnels, etc.
It's absolutely horrible, code-wise, since I tend to use this project to experiment with just about anything I think of. Current rewrite is about 2 years old, C#/.NET 5->8, UI using Tailwind and htmx, plus chartjs for the pretty pictures, although I have some custom rendering things for switch ports and traffic. Data store is SQLite, with some hacked-on time series features, and this is probably the most terrifying part of the whole mess, since I explored some really bad ideas there. But that also lead to some very good stuff for other projects, so possibly still a net win.
