How do third-party services affect performance?

Dynatrace recognizes more than 1,000 third party content providers like Google, Amazon, Twitter or LinkedIn. We detect them automatically.

Third party or CDN (Content Delivery Network)?

Typical third party content usually is a Facebook or Twitter button, a gravatar or similar resources. It is worth to monitor these types of content to know exactly how they affect your applications and to know if they are the root cause for your pages slow down.

Content delivery network (CDN) is in your control, this is usually a service that you use to have static or dynamic content on your website, for example to speed up loading in selected geographical regions.

The difference lays in the way you can affect that data. If you rely on an external resource to deliver static or dynamic content to your website, for example images or CSS you should think of this service as CDN. If you use external data and have no influence on it this is third party content.

When a host name can't be found in our list of known third party content providers we assume that it is a CDN.

To see the full list of auto-detected third party services and related configuration settings, go to Settings > Real user monitoring > Third party.

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