  title: Oracle Enterprise Manager Target Metric Trend
  summary: Resolve a target by name, then pull a metric time series over a window.
  description: >-
    Builds a performance trend for a named target. The workflow resolves the
    target by name to confirm it is monitored and capture its exact name and
    type, then queries the metric time series endpoint for numeric data points
    over the requested time range, scoped to the resolved target and the chosen
    metric group and column. Two real read operations are chained, with a branch
    that only requests the time series once a matching target has been found.
