  title: Datadog Tune Monitor Thresholds
  summary: Fetch a Datadog monitor, then update its options and alert thresholds.
  description: >-
    A tuning pattern for reducing alert noise on an existing Datadog monitor.
    The workflow reads the target monitor to capture its current query and name,
    then issues an update that replaces the monitor options with new critical
    and warning thresholds plus no-data and renotify behavior. Every step spells
    out its request inline so the flow can be read and executed without opening
    the underlying OpenAPI description.
