// 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
// tools/metrics/actions/extract_actions.py
// to add the metric to actions.xml (which will enable UMA to record your
// feature flag), then update the <owner>s and <description> sections. Make sure
// to include the actions.xml file when you upload your code for review!
//
// 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.
// See the documentation of Experiment for details on the fields.
//
// Command-line switches must have entries in enum "LoginCustomFlags" in
// histograms.xml. See note in histograms.xml and don't forget to run
// AboutFlagsHistogramTest unit test to calculate and verify checksum.
//
// When adding a new choice, add it to the end of the list.
