How to get alerted when a Azure VM is shutdown

Next I tried to use prometheus metrics

I guess there will be up metric for the job, which is collecting those windows metrics. But up metric indicates only if metric scrape was successful or not. It is not real a indicator that VM is down (there can be for example problem with network, … the same problem is with absent), but people are using it for that usually.
You can use it and group by instance and you will have almost desired result.

If you want to use absent, then:

Prometheus and Grafana Alerting for Absent Metric

There is no option to do that with absent. But you can do something similar with timeshift: create query which will group by selected labels for metric in the past (e. g. 1 hour shift) create query which will group by selected labels for current metric join these 2 queries and detect which timeseries are missing somehow - those are timeseries, which have disappeared meanwhile and you can alert on them That’s a suggestion , which can be implemented in one PromQL query.
