  title: Oracle Cloud Summarize Instance CPU Metrics
  summary: Confirm a running instance, then query summarized CPU metrics for its compartment.
  description: >-
    Correlates compute and monitoring data to report on instance utilization.
    The workflow reads a compute instance to confirm it is running, then queries
    summarized metric data over a time range so the caller can inspect CPU
    utilization for the instance's compartment. Every step spells out its request
    inline so the observability flow can be read and executed without opening the
    underlying OpenAPI description.
