CDN statistics

You can view your CDN statistics for an active domain in a content delivery server.

You must register a domain in the cockpit. If you haven’t done that, see Domains and Certificates.
The statistics sections remain empty until you enable a domain for the content delivery server.

Purge All

To purge the entire cache from the content delivery server for the domains in the selector, click Purge All. Alternatively, you can purge by URL.

For more, see Purging.

purge cdn all

It does not currently purge your Magnolia instance’s cache.

Purge URL

Instead of purging the entire cache, you may want to simply purge a single object from all cache servers. In this case, you will want to use the Purge URL option in the Cockpit.

  1. Go to Content delivery > Statistics.

  2. Under CDN Actions, click Purge URL.

    purge url

  3. In the dialog:

    1. Choose your desired Domain from the dropdown list.

    2. Enter the Full URL path of the object that you want to purge.

    3. Optionally select to perform a Soft purge.

      If unselected, a hard purge is performed which immediately makes the object inaccessible. Soft purges mark the object as stale, but it is still accessible.

      Stale objects can reduce backend loads by allowing for conditional revalidation and other performance-enhancing patterns. For more, see Fastly’s soft vs hard purge docs.

    4. Click Purge URL.
