To help developers quickly diagnose issues in production, Datadog has rolled out a comprehensive metadata catalog covering standard metrics collected by its supported integrations. This catalog provides measurement units and brief descriptions for approximately 3,000 metrics that surface automatically on graphs and dashboards. The metadata is displayed automatically on timeseries graphs, query value widgets, and toplists, with units shown in fractions of a second to milliseconds, millions of bytes per second to MiB/s, etc. Developers can find a complete list of collected metrics, their units, and descriptions under the "Metrics" tab for integrations in the Datadog app or in the docs as well. The feature is available for all standard integrations, including those for popular systems such as Redis.
