A content delivery network (CDN) is a distributed network of servers that can efficiently deliver web content to users. CDNs store cached content on edge servers in point-of-presence (POP) locations that are close to end users, to minimize latency.

Azure CDN offers developers a global solution for rapidly delivering high-bandwidth content to users by caching their content at strategically placed physical nodes across the world.

Use the Azure public cloud integration to discover and collect metrics against the Azure service.


To set up the Azure integration and discover the CDN Profile, do the following:

  1. Create an Azure Integration if not available in your installed integrations. For more information on how to install the Azure Integration, refer to Install Azure integration.

  2. Create a discovery profile.

  3. Select Azure CDN Profile under the Filter Criteria on the Edit Discovery Profile page.

  4. Save the discovery profile to make it available in the list of Discovery Profiles.

  5. Scan to discover the resources at any time independent of the predefined schedule.

  6. Once the scan is completed, you can view the CDN Profile resources under Infrastructure > Resources > Microsoft Azure category.

  7. Create a template with collector type Azure and applicable for CDN Profile. See Create a Template for more information on how to create a template.

  8. Refer to Assign a Template on how to assign a template to a resource.

  9. Click the Metrics tab to view the monitoring data of Azure CDN Profile.

Event support

OpsRamp supports Azure events for Azure CDN Profile. Configure Azure Events in OpsRamp Azure integration discovery profile. See Process Azure Events for more information on how to configure Azure events.
