  title: Oracle Cloud Create Metric Alarm
  summary: Discover a metric in a namespace, create an alarm on it, then confirm the alarm.
  description: >-
    Builds a monitoring alarm grounded in a metric that actually exists. The
    workflow lists the metrics in a compartment and namespace, creates an alarm
    whose query targets the discovered metric, and reads the alarm back to
    confirm it is active. Every step spells out its request inline so the
    alerting flow can be read and executed without opening the underlying OpenAPI
    description.

    Lists metrics to find a target metric, creates an alarm with a threshold
    query, and reads the alarm back with getAlarm.
