Observing treatment traffic - Amazon AppConfig
Services or capabilities described in Amazon Web Services documentation might vary by Region. To see the differences applicable to the China Regions, see Getting Started with Amazon Web Services in China (PDF).

Observing treatment traffic

Amazon AppConfig Agent collects aggregated treatment assignment counts and emits them as CloudWatch metrics in your account through a service-linked role that Amazon AppConfig manages. There is no additional charge for these metrics.

  • Namespace: AWS/AppConfig

  • Metric name: ReturnedCount

  • Dimensions: application ID, environment ID, configuration profile ID, flag key, and variant

These metrics show how much traffic each treatment is receiving, which you can use as a real-time check that your experiment is operating as expected. For example, in a 50/50 A/B test, you can confirm that about half of entities are assigned to the control and about half to the treatment.

Note

To emit experiment treatment traffic metrics to your account, you must opt in to the VendedMetrics account setting by using the UpdateAccountSettings operation. Vended metrics incur no additional cost.
