Units and descriptions: Understand any metric

To help users make sense of their systems quickly and eliminate ambiguity in metric interpretation, a comprehensive metadata catalog has been introduced for approximately 3,000 metrics collected by supported integrations. Metadata units are displayed automatically on timeseries graphs, query value widgets, and toplists, with descriptions available under the new "Metrics" tab for each integration in the Datadog app. This feature is now available for all standard integrations of existing Datadog customers, while those without an account can sign up for a full-featured 14-day trial.
