  title: Dell Servers Telemetry Subscription Setup
  summary: Discover metric reports and subscribe to telemetry events.
  description: >-
    Sets up streaming telemetry for a Dell PowerEdge server through the iDRAC
    Redfish API. The workflow reads the telemetry service, lists the available
    metric reports such as power, thermal, and CPU statistics, and then creates
    an event subscription that pushes MetricReport events to a caller-supplied
    destination URL. The result is a live telemetry feed without polling each
    metric report by hand. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI
    description.
