  title: Dynatrace Ingest a Custom Metric and Verify It
  summary: Push custom metric data via MINT, confirm the metric is registered, and query it back.
  description: >-
    Closes the loop on custom metric ingestion. The workflow ingests one or more
    data points using the MINT line protocol, lists metrics filtered to the new
    key to confirm Dynatrace registered the descriptor, and then queries the
    metric data back to verify the values landed. Every step spells out its
    request inline so the flow can be read and executed without opening the
    underlying OpenAPI description.
