389 // comment to the end of the feature name, like so:
390 // "my-special-feature", // FLAGS:RECORD_UMA

392 // After doing that, run
393 // tools/metrics/actions/extract_actions.py
394 // to add the metric to actions.xml (which will enable UMA to record your
395 // feature flag), then update the <owner>s and <description> sections. Make sure
396 // to include the actions.xml file when you upload your code for review!
397 //
398 // After your feature has shipped under a flag, you can locate the metrics under
399 // the action name AboutFlags_internal-action-name. Actions are recorded once
400 // per startup, so you should divide this number by AboutFlags_StartupTick to
401 // get a sense of usage. Note that this will not be the same as number of users
402 // with a given feature enabled because users can quit and relaunch the
403 // application multiple times over a given time interval. The dashboard also
404 // shows you how many (metrics reporting) users have enabled the flag over the
405 // last seven days. However, note that this is not the same as the number of
406 // users who have the flag enabled, since enabling the flag happens once,
407 // whereas running with the flag enabled happens until the user flips the flag
408 // again.
409
410 // To add a new experiment add to the end of kExperiments. There are two
411 // distinct types of experiments:
412 // . SINGLE_VALUE: experiment is either on or off. Use the SINGLE_VALUE_TYPE
413 // macro for this type supplying the command line to the macro.
414 // . MULTI_VALUE: a list of choices, the first of which should correspond to a
415 // deactivated state for this lab (i.e. no command line option). To specify
416 // this type of experiment use the macro MULTI_VALUE_TYPE supplying it the
417 // array of choices.
418 // See the documentation of Experiment for details on the fields.
419 //
420 // Command-line switches must have entries in enum "LoginCustomFlags" in
421 // histograms.xml. See note in histograms.xml and don't forget to run
422 // AboutFlagsHistogramTest unit test to calculate and verify checksum.
423 //
