Sentry onpremise monitoring/status.sentry.io

Hello

I noticed the checks on https://status.sentry.io/ but I couldn’t find how they work / what do they check. Is there a wiki/repo that contains the checks that are running for the statuspage ? Do you have somewhere a documentation on how to ensure sentry is running correctly? In docker, we can add healthchecks, but I don’t think It covers the actual running of sentry.
What URLs need to be monitored ? I found /_health/ but it’s not clear what does it check. Is there a script that can be run to check the status of all the kafka consumers /sentry workers? How can I make sure that snuba is working correctly ? The architecture is very complex and I can’t find documentation that covers the monitoring of all the flows ( besides the Datadog integration, which is not OpenSource).

Thank you
