Remote Server Monitoring over SSH

I have a group of servers where I can’t install any additional software but responsible when it goes down due to disk space. So Prometheus node exporter is a no go.

Is there a way to monitor metrics remotely via ssh like does? And display those metrics on Grafana and alert on them?

there is no current integration for a tool like that, but rtop looks pretty rad. You could probably bridge it with grafana any number of ways…
