20+ vps. Too many. Forget which have what. Monitoring needed. UptimeKuma? Perkele. Custom script? Irc bot? Server good. Price bad. Network okay. Need solution.
What do you use for monitoring 20+ cheap VPS?
They had 47 VPS and no monitoring. Found out from their abuse report for port scanning themselves. UptimeKuma is fine. Knew a guy with a custom IRC bot from 2011, still runs it. The ticket said "why does my bot say 'segfault' in #alerts".
1. UptimeKuma v1.23.11: HTTP/TCP/Ping/DNS monitoring, 20-second intervals, notification via Matrix/Signal/PagerDuty.
2. Prometheus + Grafana: heavier, better for metrics, overkill for pure uptime.
3. Custom solutions: maintainability burden increases with fleet size.
For 20+ hosts, UptimeKuma strikes the best balance. Recommend containerized deployment with SQLite backup to secondary host. End recommendation: deploy UptimeKuma, tag hosts by provider, set staggered check intervals to avoid thundering herd.
It's always DNS. Always.
