We can use the Role-based access control (RBAC) at different levels

  • Subscription Level
  • Resource Level

The RBACs which are available for Azure Monitor service are the following:

  • Monitoring Contributor
  • Monitoring Metrics Publisher
  • Monitoring Reader

Ex. A user with the Monitoring contributor access for VM1 can only consume and mange the alert that have been generated for VM1.

Add new Alert

Alerts are defined via Azure Minitor Service blade.

Go to Azure portal > Monitor service> Go to Alerts section > Use add alert rule button.

According to the seleced resource there’s different signals available.

Signal types

  • Metrics

The scope of alert is specified in this step.
– Subscription level
– Resource Group level
– Region
