Overview of DNS Service Metrics
The DNS service metrics help you measure the number of queries and zone transfers for DNS zones and DNS zones with Overview of Traffic Management policies attached.
Prerequisites 🔗
IAM policies: To monitor resources, you must be granted the required type of access in a policy written by an administrator, whether you're using the Console or the REST API with an SDK, CLI, or other tool. The policy must give you access to both the monitoring services and the resources being monitored. If you try to perform an action and get a message that you don't have permission or are unauthorized, contact the administrator to find out what type of access you were granted and which compartment you need to work in. For more information about user authorizations for monitoring, see IAM Policies.
