  • Change is not relevant to the end user.

Changes

This PR adds an alert ThanosQueryOverload to the mixins.

This alert warns the user when Thanos' query API is saturated by concurrent queries so that the user can take measurements before functionalities relying on Thanos stops working.

Good idea, I'm going to add a "Thanos Query Concurrent Capacity" dashboard with formula max_over_time(thanos_query_concurrent_gate_queries_max[5m]) - avg_over_time(thanos_query_concurrent_gate_queries_in_flight[5m])

This seems to be breaking some tests and I don't understand why. 🤔

Does someone have ideas? cc @bwplotka, @kakkoyun, @fpetkovski

The broken test has been fixed, just need to add a stub rule in the testing code.
