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.

0-CRITICAL	Critical	<= 4 hrs
1-ERROR	High	<= 12hrs
2-WARNING	Medium	<= 48hrs (2days)
3 - Informational	Low	<= 96hrs (4days)
4 - Verbose	No Ticket	Action based on the notification and analysis

Requirements

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
