  title: Dynatrace Metrics API v2
  version: 2.0.0
  description: >-
    The Dynatrace Metrics API v2 allows you to query, ingest, and manage
    time-series metric data within a Dynatrace environment. It supports
    retrieving metric descriptors, querying data points with flexible selectors
    (including transformations and aggregations), and ingesting custom metrics
    from external sources using the MINT line protocol.
