Set up alerts on metrics for Azure Database for MySQL - Flexible Server

  • आलेख

APPLIES TO: Azure Database for MySQL - Flexible Server

This article shows you how to set up Azure Database for MySQL flexible server instance 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. Metric alerts are stateful, that is, they only send out notifications when the state changes.

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 other emails that you specify
  • Call a webhook

You can configure and get information about alert rules using:

Create an alert rule on a metric from the Azure portal

  1. In the Azure portal, select the Azure Database for MySQL flexible server instance you want to monitor.

  2. Under the Monitoring section of the sidebar, select Alerts.

  3. Select + New alert rule.

  4. The Create rule page opens. Fill in the required information.

  5. Within the Condition section, choose Select condition.

  6. You'll see a list of supported signals, select the metric you want to create an alert on. For example, select Storage percent.

  7. You'll see a chart for the metric for the last six hours. Use the Chart period dropdown to select to see longer history for the metric.

  8. Select the Threshold type (ex. "Static" or "Dynamic"), Operator (ex. "Greater than"), and Aggregation type (ex. average). This selection determines the logic that the metric alert rule will evaluate.

    • If you're using a Static threshold, continue to define a Threshold value (ex. 85 percent). The metric chart can help determine what might be a reasonable threshold.
    • If you're using a Dynamic threshold, continue to define the Threshold sensitivity. The metric chart will display the calculated thresholds based on recent data. Learn more about Dynamic Thresholds condition type and sensitivity options.

  9. Refine the condition by adjusting Aggregation granularity (Period) interval over which data points are grouped using the aggregation type function (ex. "30 minutes"), and Frequency (ex "Every 15 Minutes").

  10. Select Done.

  11. Add an action group. An action group is a collection of notification preferences defined by the owner of an Azure subscription. Within the Action Groups section, choose Select action group to select an already existing action group to attach to the alert rule.

  12. You can also create a new action group to receive notifications on the alert. For more information, see create and manage action group.

  13. To create a new action group, choose + Create action group. Fill out the Create action group form with a Subscription, Resource group, Action group name and Display Name.

  14. Configure Notifications for action group.

    In Notification type, choose Email Azure Resource Manager Role to select subscription Owners, Contributors, and Readers to receive notifications. Choose the Azure Resource Manager Role for sending the email. You can also choose Email/SMS message/Push/Voice to send notifications to specific recipients.

    Provide Name to the notification type and select Review + Create when completed.

  15. Fill in Alert rule details like Alert rule name, Description, Save alert rule to resource group and Severity.

  16. Select Create alert rule to create the alert. Within a few minutes, the alert is active and triggers as previously described.

Manage your alerts

Once you create an alert, you can select it and do the following actions:

  • View a graph showing the metric threshold and the actual values from the previous day relevant to this alert.
  • Edit or Delete the alert rule.
  • Disable or Enable the alert, if you want to temporarily stop or resume receiving notifications.
