  title: Dynatrace Service Health Snapshot
  summary: Resolve a service, read a key metric, and list its open problems and recent events.
  description: >-
    Assembles a one-shot health snapshot for a named service across three
    monitoring domains. The workflow resolves the service by name, queries a key
    performance metric scoped to it, lists open problems affecting it, and lists
    recent events on its timeline. Every step spells out its request inline so
    the flow can be read and executed without opening the underlying OpenAPI
    description.
