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?

If you don’t have another server, this is likely your best option. It’s a simple app, that pings the website on a given interval and gives an app notification if it can’t reach it.
