496 // After doing that, run
497 // tools/metrics/actions/extract_actions.py
498 // to add the metric to actions.xml (which will enable UMA to record your
499 // feature flag), then update the <owner>s and <description> sections. Make sure
500 // to include the actions.xml file when you upload your code for review!
501 //
502 // After your feature has shipped under a flag, you can locate the metrics under
503 // the action name AboutFlags_internal-action-name. Actions are recorded once
504 // per startup, so you should divide this number by AboutFlags_StartupTick to
505 // get a sense of usage. Note that this will not be the same as number of users
506 // with a given feature enabled because users can quit and relaunch the
507 // application multiple times over a given time interval. The dashboard also
508 // shows you how many (metrics reporting) users have enabled the flag over the
509 // last seven days. However, note that this is not the same as the number of
510 // users who have the flag enabled, since enabling the flag happens once,
511 // whereas running with the flag enabled happens until the user flips the flag
512 // again.

514 // To add a new experiment add to the end of kExperiments. There are two
515 // distinct types of experiments:
516 // . SINGLE_VALUE: experiment is either on or off. Use the SINGLE_VALUE_TYPE
517 // macro for this type supplying the command line to the macro.
518 // . MULTI_VALUE: a list of choices, the first of which should correspond to a
519 // deactivated state for this lab (i.e. no command line option). To specify
520 // this type of experiment use the macro MULTI_VALUE_TYPE supplying it the
521 // array of choices.
522 // See the documentation of Experiment for details on the fields.
523 //
524 // Command-line switches must have entries in enum "LoginCustomFlags" in
525 // histograms.xml. See note in histograms.xml and don't forget to run
526 // AboutFlagsHistogramTest unit test to calculate and verify checksum.
