Netdata is exactly what you’re looking for. It’s basically an all in one monitoring and and alerting suite that collects and analyzes data, and provides a gorgeous web dashboard for you to view.
You can also manually replicate this using Prometheus, Grafana and other tools, but that requires a much bigger effort to set up.
Edit: There’s a public demo instance where you can try everything out: https://frankfurt.netdata.rocks/
Oh that sucks. I haven’t used it personally in quite a while, since I switched to the Grafana stack
