Recommended Azure Monitors
General
This document describes the recommended Azure monitors which can be implemented in Azure cloud application subscriptions.
SMT incident priority mapping
The priority “Blocker” is mostly used by Developers to prioritize their tasks and its not applicable for operations team.

ACR ACR - To trigger alert when Create or Update Images from the ACR ? SQL DB SQL DB - Slow / Long running Queries ? Service Principal secret / certificate expiry ? AKS Check if we can sent an alert if k8s is not able to scale in new workernode VISUALIZATION KURED/AKS ALERTS Currently we dont have a Dashboard / Vis for kured alertsA overview over time would be helpful to
