I've been using uptime Kuma recently and it's great but works better outside of docker.
Inside docker I'd get a lot of false down positives from I assume docker throttling the checks.
Plus it works with email, telegram, and matrix chat alerts. I monitor all my clients sites with it, and it's bullet proof behind caddy.
For light touch monitoring this is my approach too. I have one instance in my network, and another on fly.io for the VPSs (my most common outage is my home internet). To make it a tiny bit stronger, I wrote a Go endpoint that exposes the disk and memory usage of a server including with mem_okay and disk_okay keywords, and I have Kuma checking those.
I even have the two Kuma instances checking each other by making a status page and adding checks for each other's 'degraded' state. I have ntfy set up on both so I get the Kuma change notifications on my iPhone. I love ntfy so much I donate to it.
For my VPSs, this is probably not enough, so I am considering the more complicated solutions (I've started wanting to know things like an influx of fali2ban bans etc.)
I just do web hosting for clients sites and use Kuma to monitor uptime and SSL certificates.
Ive got multiple Kuma's running as well.
