The metric Impact tab
The metric Impact tab displays a list of complete experiment iterations that used the metric. Any experiment iterations that are currently running do not display on this list. This helps you understand how different flag variations have impacted the metric as part of your Experimentation program. This list includes:- The name of the experiment or flag the metric was attached to.
- The date the experiment iteration or guarded rollout ended.
- The variation that was served after the experiment iteration or guarded rollout ended.
- The relative difference from control, which is the difference in performance between the variation being tested and the control variation.
