gatus VS Healthchecks

You can have a look at Gatus but I don't know how it will handle that many hosts (I have maybe 30). It has an API but it's read only, however the config file is monitored so you could probably write a script to dynamically add and remove hosts.

I create a health status page in Go nearly a year ago.

I'm also making a SaaS out of it, though it's still a work in progress: gatus.io

Another alternative I found here on HackerNews in another "Uptime Robot Alternatives Thread" and which I use in my home setup is https://github.com/TwiN/gatus . Very easy setup and configuration.

For those looking for a lightweight alternative to Uptime Kuma there is Gatus. It's written in Go and it's really really fast. It also has a status page and notifications support.

Gatus is another self-hosted open source uptime monitor but with more customisable alerts and also has uptime badges for websites - https://github.com/TwinProduction/gatus #gatus

Gatus ftw.

Now, arriving at a summerhouse where the fridge has been unpowered for a week or two is not something I’d recommend, and I solved it by setting up a Raspberry Pi Zero on the same breaker circuit, and having it call Healthchecks.IO every 15 minutes. It’s just a simple curl call in Cron.

I wrote a python library to make managing healthchecks.io checks easier.

Replace the echo with something like https://healthchecks.io and add it to a daily cron and you’re good.

Sometimes I just want to run simple cron jobs and forget about it. I don't want to think about monitoring it. This is where I found https://healthchecks.io/ so useful. It gave me easy access to monitoring my jobs. However, it's some work to use if you are limited in time. That's why I created a python wrapper around your job and forget about all the housekeeping.

For your last point: That is the reason I implemented https://healthchecks.io/ into my jobs.

And here I am of course thinking of Healthchecks.io, but there are good alternatives too. The monitoring service provides an unique URL that the housekeeping script must request regularly. When an HTTP request from the script does not arrive on time, Healthchecks.io detects that and alerts you. This takes care of scenarios, where, for example, the server has been shut down, and so is unable to contact you by itself. Healthchecks.io offers a lot more features, but this is the basic idea.

Finally, while setting up a “fire and forget” solution, it is worthless if it doesn’t run. For keeping an eye on things, i would recommend something like Healthchecks.IO . Their free tier gives you the option to monitor 20 different tasks, and will alert you on error or if the back fails to run.

Self-hosted Open Distro ElasticSearch/Kibana for logging and statistics, https://uptimerobot.com/ for uptime alerts, https://healthchecks.io/ for server & backup healthchecks (load/storage space/sanity check if containers are running etc)
