| // RECORDING USER METRICS FOR FLAGS: |
| // ----------------------------------------------------------------------------- |
| // The first line of the experiment is the internal name. If you'd like to |
| // gather statistics about the usage of your flag, you should append a marker |
| // comment to the end of the feature name, like so: |
| // "my-special-feature", // FLAGS:RECORD_UMA |
| // |
| // After doing that, run //chrome/tools/extract_actions.py (see instructions at |
| // the top of that file for details) to update the chromeactions.txt file, which |
| // will enable UMA to record your feature flag. |
| // |
| // After your feature has shipped under a flag, you can locate the metrics under |
| // the action name AboutFlags_internal-action-name. Actions are recorded once |
| // per startup, so you should divide this number by AboutFlags_StartupTick to |
| // get a sense of usage. Note that this will not be the same as number of users |
| // with a given feature enabled because users can quit and relaunch the |
| // application multiple times over a given time interval. The dashboard also |
| // shows you how many (metrics reporting) users have enabled the flag over the |
| // last seven days. However, note that this is not the same as the number of |
| // users who have the flag enabled, since enabling the flag happens once, |
| // whereas running with the flag enabled happens until the user flips the flag |
| // again. |
| |
| // To add a new experiment add to the end of kExperiments. There are two |
| // distinct types of experiments: |
| // . SINGLE_VALUE: experiment is either on or off. Use the SINGLE_VALUE_TYPE |
| // macro for this type supplying the command line to the macro. |
| // . MULTI_VALUE: a list of choices, the first of which should correspond to a |
| // deactivated state for this lab (i.e. no command line option). To specify |
| // this type of experiment use the macro MULTI_VALUE_TYPE supplying it the |
| // array of choices. |
