You can't. This is not what Cockpit does -- there is literally nothing running on a system (other than the systemd socket unit) until someone logs into Cockpit, and afterwards everything goes away again. Also, Cockpit has no notification/communication methods, and isn't going to get any. > "I think there may be better channels sharing info about alerting and > monitoring sysOps, but surely using an stack like grafana, prometheus, > telegraf... could help you.

For monitoring you need *something* on the system that regularly probes it; that can be a permanently running daemon, or a cron job, or a cron job on a remote site which regularly SSHs into the system to collect a data snapshot and sends it off somewhere else. Gil already mentioned Grafana/prometheus as the de-facto standard monitoring solution these days. They can both be deployed into a container somewhere centrally, and the managed machines only have to run PCP (in particular, pmproxy) and redis (also easily installed). Cockpit supports that, and I recently wrote about this [1]. That also has a link for how to automate the PCP/redis setup on the watched machines [2], it's just three commands. Another very popular monitoring software is https://www.nagios.org/ . I don't have personal experience with that, though.
