In general, when running any experiment, it is important to know what it is that is being measured to determine the success or failure of the test. There could be more than one metric being collected and analyzed, but for most experiments, there is just one.

The second screen of the Experiments dashboard shows all the metrics that have been set up for a project:
Figure 11.4 – The Metrics dashboard
Similar to the dashboards we have seen throughout this book, such as Feature flags and Users, there is the ability to search for metrics. This can be done by using their name or description. It is possible to filter the metrics and to sort the list by several attributes. The metrics themselves show how many flags have experiments set up (Flags) that use the metric, the type of event that the metric collects data on (Event...
