  title: Dynatrace Find Problems Affecting a Named Service
  summary: Resolve a service by name, read its details, and list problems impacting it.
  description: >-
    Answers "is this named service healthy?" by chaining entity resolution with
    problem discovery. The workflow looks up the service by its display name to
    obtain the entity ID, reads the entity for context, and then lists problems
    scoped to that entity. Every step spells out its request inline so the flow
    can be read and executed without opening the underlying OpenAPI description.
