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?
I recommend the free tier of healthchecks.io for this. I have all of my in-depth monitoring selfhosted, but use this as a general “is it at least online” check that tells me on multiple platforms if it isnt.
