Assign a role assignment using the az role assignment create command.

In the code below, replace the following placeholders:

• <assignee>: If its --assignee parameter then enter the assignee's object ID or user sign-in name or service principal name. If its --assignee-object-id parameter then enter object IDs for users or groups or service principals or managed identities. For managed identities use the principal ID. For service principals, use the object ID and not the app ID. For more information, refer az role assignment create command.
• <roleNameOrId>: Enter the role's name or ID. For Monitoring Reader, enter Monitoring Reader or 43d0d8ad-25c7-4714-9337-8ba259a9fe05.
• <scope>: Enter the full ID of the resource Azure Managed Grafana needs access to.

az role assignment create --assignee "<assignee>" \
--role "<roleNameOrId>" \
--scope "<scope>"

or

az role assignment create --assignee-object-id "<assignee>" --assignee-principal-type "<ForeignGroup / Group / ServicePrincipal / User>" \
--role "<roleNameOrId>" \
--scope "<scope>"

Example: assigning permission for an Azure Managed Grafana instance to access an Application Insights resource using a managed identity.

az role assignment create --assignee-object-id "abcdef01-2345-6789-0abc-def012345678" --assignee-principal-type "ServicePrincipal" \
--role "Monitoring Reader" \
--scope "/subscriptions/abcdef01-2345-6789-0abc-def012345678/resourcegroups/my-rg/providers/microsoft.insights/components/myappinsights/"
