What are my options for getting alerts on my android phone if services on my VPS becoming unresponsive?
My first thought is a simple app that periodically pings domains and gives a notification if any fail. Is there an open source app for that?
Or something else?
+1 for Uptime Kuma, I use it with ntfy. If OP doesn’t want a self hosted solution, there’s UptimeRobot - essentially SAAS Uptime Kuma, but with a free tier.
