- FunctionMetricsResponse
  - `project` object, required
    - `id` string, required
  - `function` object, required
    - `id` string, required
    - `name` string, required
  - `timeRange` '15m' | '1h' | '3h' | '1d', required
  - `windowStart` string, date-time, required
  - `windowEnd` string, date-time, required: End of the completed 5-minute grid used by the resource series.
  - `bucketStarts` string[], required
  - `availability` 'ready' | 'partial' | 'unavailable', required
  - `serviceLevel` FunctionServiceLevel, required: Function Access traffic for the window through the read time, including requests already recorded in the in-progress interval. A live window is evaluated as of the oldest open Gateway store cut, which must be at most 7 minutes old; windows ending before that cut are evaluated strictly.
    - `trafficAvailability` 'ready' | 'partial' | 'unavailable', required: ready: coverage is complete as of asOf; partial: recorded values are shown but some requests may be unconfirmed; unavailable: no request is recorded and the window is not confirmed empty.
    - `asOf` string, date-time, nullable, required: Combined Gateway store cut the coverage is evaluated at.
    - `availability` FunctionServiceLevelMetric, required
      - `value` union, required
        - number
        - string
      - `unit` 'percent' | 'millisecond', required
    - `totalRequests` integer, nullable, required: Null when no request is recorded and the window is not confirmed empty.
    - `successfulRequests` integer, nullable, required
    - `successfulRequestRate` FunctionServiceLevelMetric, required
      - `value` union, required
        - number
