Azure SQL Data Warehouse (legacy)
The Azure SQL Data Warehouse overview page gives you a comprehensive view of how many jobs and tasks were completed over a period of time. You can also track nodes in different states, such as running, idle, or offline.
Prerequisites
- Dynatrace version 1.224+
- Environment ActiveGate version 1.205+
Enable monitoring
To enable monitoring for Azure SQL Data Warehouse, you first need to set up integration with Azure Monitor.
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
- In the Dynatrace menu, go to Settings > Cloud and virtualization > Azure and select Edit for the desired Azure instance.
- For Resources to be monitored, select Monitor resources selected by tags.
- Enter the Key and Value.
- Select Save to save your configuration.
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
- In the Dynatrace menu, go to Technologies.
- Filter by service name and select the relevant custom device group.
- Once you select the custom device group, you're on the custom device group overview page.
- 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.
Available metrics
Note: This service monitors the data warehouse type of SQL Databases. You can find the already monitored resources on the Azure overview page in the Cloud services section. To monitor the SQL Databases user kind, check Azure SQL Servers and the Databases components sections on the Azure overview page.

| Workload group active queries | The active queries within the workload group. Using this metric unfiltered and unsplit displays all active queries running on the system. | Is user defined, workload group | Count | |
| Workload group allocation by cap resource percent | ||||
| The percentage allocation of resources relative to the effective cap resource percent per workload group. This metric provides the effective utilization of the workload group. | Is user defined, Workload group. | Percent | ||
| Workload group allocation by system percent | The percentage allocation of resources relative to the entire system. | Is user defined, workload group | Percent | |
| Workload group query timeouts | Queries for the workload group that have timed out. | Is user defined, workload group | Count | |
