  title: Cisco Expressway Capacity and Registrations Audit
  summary: Read resource usage, then list registrations and active calls to audit load.
  description: >-
    Audits the current load on an Expressway by reading resource usage metrics,
    listing all current device registrations, and listing all active calls so the
    registration and call counts can be reconciled against capacity. Every step
    spells out its request inline so the flow can be read and executed without
    opening the underlying OpenAPI description.
