Query Explanation

The query selects HPAs where the ScalingLimited condition is true and checks if the remaining capacity (maxReplicas - desiredReplicas) is zero; when this is the case, the HPA cannot scale further. The alert fires when an HPA has reached its maximum replica limit while scaling is limited.
