Ask HN: Mature tools for availability when app shutdown outside of buisness hour
I just joined a new company in the observability team. We used Datadog for observability. Datadog support computing app availability based on unsuccessful monitoring checks that can happen. However as i learned when joining the company, this won't work in our case.
Why? : The vast majority ( 500+) of the company app don't run 24*7, they have different business hours ( like 9-5) but outside of these business hours, apps are shutdown. So for example for a 9-5 , app will be shutdown at 5 and restart tomorrow at 9. And Datadog don't support that. It has maintenance window but they can not be scheduled, the same is valid for monitoring mute.
So the team ( I was not there at this moment) tried to code a scheduler to send through API maintenance windows each day but the datadog availability computation was not correct.They decided to build their own tool which took as sources: datadog unsuccessful checks + table of business hours per app and allow to calculate app availability. The results were correct.
However as I joined the team, I found that this code will be very difficult to maintain at longer term. So if someone knows a tool ( preferably opensource but i am open) that can help, i am interested. PS: The tool can't be a datadog alternative because the observability platform can be changed.
