When our customers make changes to improve performance, they use Rigor to measure the impact. To make it easier to identify the cause of performance changes, we’ve expanded our Control Groups to support annotations.

Control Group annotations allow you to add events to the Performance History and Activity Stream of your Rigor Checks. These annotations then serve as a record of what changes were made and when, making it easy to find the cause of performance improvements or regressions.

Using Control Group Annotations

New Control Group

  • Copy the API endpoint and post token used for annotating your Control Group. The endpoint and post token can be found by clicking the Help button on the Control Group page.

  • Using cURL (or your favorite HTTP client), send a request to the API endpoint with the Control Group post token, the annotate command, and a message and title (optional). Our system adds a timestamp to your annotation automatically.
  • Visit the Performance History or Activity Stream for any Check in your Control Group to view your annotation. (Click the flag icon if you don’t see the annotation in the Performance History.)
