413 // comment to the end of the feature name, like so:
414 // "my-special-feature", // FLAGS:RECORD_UMA
415 //
416 // After doing that, run
417 // tools/metrics/actions/extract_actions.py
418 // to add the metric to actions.xml (which will enable UMA to record your
419 // feature flag), then update the <owner>s and <description> sections. Make sure
420 // to include the actions.xml file when you upload your code for review!
421 //
422 // After your feature has shipped under a flag, you can locate the metrics under
423 // the action name AboutFlags_internal-action-name. Actions are recorded once
424 // per startup, so you should divide this number by AboutFlags_StartupTick to
425 // get a sense of usage. Note that this will not be the same as number of users
426 // with a given feature enabled because users can quit and relaunch the
427 // application multiple times over a given time interval. The dashboard also
428 // shows you how many (metrics reporting) users have enabled the flag over the
429 // last seven days. However, note that this is not the same as the number of
430 // users who have the flag enabled, since enabling the flag happens once,
431 // whereas running with the flag enabled happens until the user flips the flag
432 // again.
433
434 // To add a new experiment add to the end of kExperiments. There are two
435 // distinct types of experiments:
436 // . SINGLE_VALUE: experiment is either on or off. Use the SINGLE_VALUE_TYPE
437 // macro for this type supplying the command line to the macro.
438 // . MULTI_VALUE: a list of choices, the first of which should correspond to a
439 // deactivated state for this lab (i.e. no command line option). To specify
440 // this type of experiment use the macro MULTI_VALUE_TYPE supplying it the
441 // array of choices.
442 // See the documentation of Experiment for details on the fields.
443 //
444 // Command-line switches must have entries in enum "LoginCustomFlags" in
445 // histograms.xml. See note in histograms.xml and don't forget to run
446 // AboutFlagsHistogramTest unit test to calculate and verify checksum.
