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?
This is what I use, though I run it on a local server that checks services that it runs (update breaks something, etc) and then also reaches out to the vps (and more) for status checks. Have it check services that are accessible by an access control rule, so the server is protected but you have updates on exactly what is having issues.
