-  * **Data:** Unlike classic external services, the transaction-level detail of distributed tracing is based on sampling instead of metrics. This sampled data links into distributed tracing, which can give you deeper insights into what’s driving the performance of the transactions.

 ## When would you use external services? [#when-to-use]
 
 The external services feature is a tool you can use by itself to tune or troubleshoot a specific service. You can also use it as a starting point for additional troubleshooting with distributed tracing.

   1. Drill into distributed tracing and see in the trace that the calls in this transaction are doing something odd.
   2. Jump to that transaction on service B and see that it got slow after a deploy.

-    When distributed tracing is enabled for an application, external calls do not have internal transaction details at **[one.newrelic.com](https://one.newrelic.com) > APM > (select an app) > Monitor > External services > (select external service)**.
