How do third-party services affect performance?

Dynatrace automatically recognizes more than 1,000 third-party content providers, including Google, Amazon, Twitter, and LinkedIn.

Third-party or CDN (Content Delivery Network)?

Typical third-party content includes Facebook and Twitter widgets, gravatars, and similar resources. It's worth monitoring this type of content to know exactly how it affects your applications and to understand if such content is the root cause of any page slow-downs.

CDNs are typically under your control. Typically your website will use a CDN to store and serve frequently-accessed static and dynamic content so as to speed up load times in certain geographic regions.

The difference between third-party content and CDNs lays in the control you have over the data. If you rely on an external resource to deliver static or dynamic content to your website, for example images or CSS, think of the service as a CDN. If you use external data that you have no control over, the content is third-party content.

When a host name can't be found in our list of known third-party content providers, Dynatrace assumes that the host is a CDN.

To see the full list of manual and auto-detected third-party and CDN services we detect out of the box, along with related configuration settings, go to Settings > Web and mobile monitoring > Provider breakdown. For Auto-detected providers, sort the list by resource type to see all third-party and CDN services.

Dynatrace settings allow you to ignore specific third-party content providers or CDNs. You can also add custom host names and have Dynatrace categorize them as either CDNs or third parties.
