Petals MemoryInstall

Summary

Records one numeric observation for a Petals metric, creating or updating its definition from the supplied metric details. The node sends the reading and definition to Petals for each input item.

Inputs

• Slug (required) — Stable lowercase snake_case identifier for the metric, such as body_weight.
• Label (required) — Human-readable metric name.
• Description (required) — What the metric captures.
• Unit (required) — Measurement unit, such as kg or bpm.
• Aggregation Hint — How values aggregate over a window: average (default), maximum, minimum, or sum.
• Value (required) — Numeric reading to record.
• Occurred At (required) — ISO 8601 timestamp for when the reading occurred; valid dates are sent in UTC.
• Additional Fields: Note — Optional short note attached to the observation.
• Additional Fields: Valid Range Max — Optional upper bound included in the metric definition for sanity validation.
• Additional Fields: Valid Range Min — Optional lower bound included in the metric definition for sanity validation.

Output shape

One item per response row, containing the Petals API response as JSON.

The operation sends a POST request to record the metric definition and observation. If the API returns an array, each element becomes a separate output item; otherwise the response is returned as one item. With Continue On Fail enabled, errors are returned as items with an error field.
