Original GitHub issue: https://github.com/healthchecks/healthchecks/issues/1220

I just found this project while looking for actively maintained receivers of an Alertmanager Watchdog alert / Dead Man's Switch - but only after searching for quite some time, and finally asking AI in an act of desperation.

I saw that work was done for making healthchecks observable by Prometheus some while ago in #300 - but I'm quite surprised that I don't find any mentions or issues here about Alertmanager!

As far as I can tell at the moment, healthchecks not only is open and maintained, but also offers way more features & integrations than I expected, making it tempting to use it for other cases as well

I still have to give this a try, but thought it would be a good idea to raise this issue to either share my findings and experiences when eventually integrating & testing this in the coming weeks, or to discuss ideas for changes if anything could be done smoother.

Until then, I hope it's at least a bit easier to find through search engines when looking for Alertmanager Watchdog / Dead Man's Switch receivers after mentioning it here :)

If there will be anything to document (config examples, mention in supported integrations (both in your docs, as well as for Alertmanager), I'm happy to create PRs.
Still happy doing code changes as well if something can be improved, but don't want to promise any big PRs due to time constraints, and not having looked at the code base yet ;)

1 question on the side: is the metrics endpoint for healthchecks also available for the hosted offering?

AI was actually only involved in the Google search for finding this repo. The text above is 100% my own - sorry if it was too "sloppy".

The improvement I'd like to suggest is to at least mention this as a use case in the documentation, explore how well Alertmanager and healthchecks works together, and (if necessary) making adjustments to improve their integration.

I'll try to get it up and running and get back with a new issue, when I have more to tell than wondering if I'm the first to use healthchecks & Alertmanager together.
