# When developing usage data metrics use the below usage data interface methods
# unless you have good reasons to implement custom usage data
# See `lib/gitlab/utils/usage_data.rb`
#
# Examples
#   issues_using_zoom_quick_actions: distinct_count(ZoomMeeting, :issue_id),
#   active_user_count: count(User.active)
#   alt_usage_data { Gitlab::VERSION }
#   redis_usage_data(Gitlab::UsageDataCounters::WikiPageCounter)
#   redis_usage_data { Gitlab::UsageDataCounters::HLLRedisCounter.unique_events(event_names: 'users_expanding_vulnerabilities', start_date: 28.days.ago, end_date: Date.current) }

# NOTE:
# Implementing metrics direct in `usage_data.rb` is deprecated,
# please add new instrumentation class and use add_metric method.
# For more information, see https://docs.gitlab.com/ee/development/service_ping/metrics_instrumentation.html
