Azure Database for MariaDB monitoring

On the Azure Database for MariaDB overview page you can see if you’re running out of CPU or facing a high I/O percentage, so you always know which queries need to be optimized.

Prerequisites

  • Dynatrace version 1.196+
  • Environment ActiveGate version 1.195+

Enable monitoring

To enable monitoring for Azure Database for MariaDB, you first need to set up integration with Azure Monitor.
Optionally, for OneAgent integration, see how database activity is monitored.

Add the service to monitoring

In order to view the service metrics, you must add the service to monitoring in your Dynatrace environment.

Monitor resources based on tags

You can choose to monitor resources based on existing Azure tags, as Dynatrace automatically imports them from service instances.

To monitor resources based on tags

  1. In the Dynatrace menu, go to Settings > Cloud and virtualization > Azure and select the Azure instance.
  2. For Resource monitoring method, select Monitor resources based on tags.
  3. Enter the Key and Value.
  4. Select Save.

Note: To import the Azure tags automatically into Dynatrace, enable Capture Azure tags automatically.

Configure service metrics

Once you add a service, Dynatrace starts automatically collecting a suite of metrics for this particular service. These are recommended metrics.

Recommended metrics:

  • Are enabled by default
  • Can't be disabled
  • Can have recommended dimensions (enabled by default, can't be disabled)
  • Can have optional dimensions (disabled by default, can be enabled).

Apart from the recommended metrics, most services have the possibility of enabling optional metrics.

Optional metrics:

  • Can be added and configured manually

View service metrics

You can view the service metrics in your Dynatrace environment either on the custom device overview page or on your Dashboards page.

View metrics on the custom device overview page

To access the custom device overview page

  1. In the Dynatrace menu, go to Technologies.
  2. Filter by service name and select the relevant custom device group.
  3. Once you select the custom device group, you're on the custom device group overview page.
  4. The custom device group overview page lists all instances (custom devices) belonging to the group. Select an instance to view the custom device overview page.

View metrics on your dashboard

Once you add a service to monitoring, a preset dashboard for the respective service containing all recommended metrics is automatically created on your Dashboards page. You can look for specific dashboards by filtering by Preset and then by Name.

Note: For existing monitored services, you might need to resave your credentials for the preset dashboard to appear on the Dashboards page. To resave your credentials, go to Settings > Cloud and virtualization > Azure, select the desired Azure instance, then select Save.

You can't make changes on a preset dashboard directly, but you can clone and edit it. To clone a dashboard, open the browse menu () and select Clone.
To remove a dashboard from the dashboards list, you can hide it. To hide a dashboard, open the browse menu () and select Hide.
Note: Hiding a dashboard doesn't affect other users.

Set up a management zone

To import a dashboard for Azure Database for MariaDB, you need to set up a management zone to limit the entities displayed on the dashboard to those relevant to this service.

When you create a management zone for this dashboard:

  1. Create a rule that identifies services based on a common property:
    • Service type: Database
    • Technology: MariaDB
    • Service topology: Opaque service
  2. Add a condition for the database name to contain the mariadb string (case sensitive.)

After you create the management zone, select it from your dashboard (Edit > Settings > Default management zone). For more information, see Dashboard timeframe and management zone.
