Using Azure DNS metrics
Azure DNS provides metrics for you to monitor specific aspects of your DNS zones. With the metrics in Azure DNS, you can configure alerting based on conditions that are met. Azure DNS provides the following metrics to Azure Monitor for your DNS zones:
- QueryVolume
- RecordSetCount
- RecordSetCapacityUtilization
Note
At this time, these metrics are only available for Public DNS zones hosted in Azure DNS. If you have Private Zones hosted in Azure DNS, these metrics don't provide data for those zones. In addition, the metrics and alerting feature is only supported in Azure Public cloud. Support for sovereign clouds will follow at a later time.
The most granular element that you can see metrics for is a DNS zone. You currently can't see metrics for individual resource records within a zone.
Query volume
The Query Volume metric shows the number of DNS queries received by Azure DNS for your DNS zone. The unit of measurement is Count and the aggregation is the Sum of all the queries received over a period of time.
To view this metric, select Metrics explorer experience from the Monitor page in the Azure portal. Scope down to your DNS zone and then select Apply. In the drop-down for Metrics, selectQuery Volume, and then select Sum from the drop-down for Aggregation.
Record Set Count
The Record Set Count metric shows the number of Record sets in Azure DNS for your DNS zone. All the Record sets defined in your zone are counted. The unit of measurement is Count and the aggregation is the Maximum of all the Record sets.
To view this metric, select Metrics explorer experience from the Monitor tab in the Azure portal. Scope down to your DNS zone and then select Apply. In the drop-down for Metrics, select Query Volume, and then select Sum from the drop-down for Aggregation.
Select your DNS zone from the Resource drop-down, select the Record Set Count metric, and then select Max as the Aggregation.
Record Set Capacity Utilization
The Record Set Capacity Utilization metric shows the percentage used of your Record set capacity for a DNS Zone. Each Azure DNS zone has a Recordset limit that defines the maximum number of Record sets allowed for the zone. For more information, see DNS limits section. The unit of measurement is a Percentage and the aggregation type is Maximum.
For example, if you have 500 Record sets configured in your DNS zone, and the zone has the default Record set limit of 5000. The RecordSetCapacityUtilization metric shows the value of 10%, which is obtained by dividing 500 by 5000.
To view this metric, select Metrics explorer experience from the Monitor tab in the Azure portal. Scope down to your DNS zone and then select Apply. In the drop-down for Metrics, select Record Set Capacity Utilization, and then select Sum from the drop-down for Aggregation.
Metric dimensions
For information about what metric dimensions are, see Multi-dimensional metrics.
This service has the following dimensions associated with its metrics.
- EndpointId
