Use the Azure portal to set up alerts on metrics for Azure Database for MariaDB
This article shows you how to set up Azure Database for MariaDB alerts using the Azure portal. You can receive an alert based on monitoring metrics for your Azure services.
The alert triggers when the value of a specified metric crosses a threshold you assign. The alert triggers both when the condition is first met, and then afterwards when that condition is no longer being met.
You can configure an alert to do the following actions when it triggers:
- Send email notifications to the service administrator and co-administrators
- Send email to additional emails that you specify.
- Call a webhook
You can configure and get information about alert rules using:
