| experiments.metrics.active_experiment |[string](https://mozilla.github.io/glean/book/user/metrics/string.html) |Records the branch name of the active experiment, if the client is enrolled in the `fenix-test-2019-08-05` experiment. This is intended to validate that the service-experiments library properly matches clients to experiments and can take action based on a multi-branched experiment. This is done by recording the experiment branch name in this string metric which allows the experiment to be transparent and unobtrusive to the user. |[1](https://bugzilla.mozilla.org/show_bug.cgi?id=1543986#c4)||2019-11-01 |
