  title: Mux Metric Breakdown Analysis
  summary: Read a metric's overall value for a timeframe, then break it down by a dimension to see which segments drive it.
  description: >-
    A core Mux Data analytics pattern that puts a single quality-of-experience
    metric in context. The workflow fetches the overall value of a metric across
    a timeframe to establish the baseline, then breaks the same metric down by a
    grouping dimension such as browser, country, or CDN so you can see which
    segments are pulling the number up or down. Every step spells out its request
    inline so the flow can be read and executed without opening the underlying
    OpenAPI description.
