I'm actively building Zero Monitor, a tool to really quickly monitor servers, vms, vps, etc. The main selling point is the overview of resources usage (your typical CPU, RAM, Disk, Rx/Tx), but the tool comes battery charged and also allows you to:

- query system packages - query network connections (tcp/udp level) - interface system processes (task manager) - measure internet connectivity with speedtests

If this sounds interesting to you, I invite you to take a quick look in the beta instance: https://beta.zero-monitor.guackamollyapps.com/network

Or if you want to jump in and try in your server fleet, see the get started page: https://guackamollyapps.com/zero-monitor/docs/get-started
