Metric.define

Compiles a number from your Events and lists every Event it reads, so no one types it in.

Its Inputs, Outputs, Effects and guards quote the hub’s Metric.define; this page adds what each Venue honors, its limits and a worked call. It is one of the Verbs of Analytics and experiments.

Inputs

NameTypeDefaultMeaning
namestringRequiredThe Metric’s name.
querytextRequiredThe query, over Events and Entries.
unitstringRequiredWhat one unit of it is.

Outputs

FieldTypeWhat null means
metricMetricNever null: the defined Metric.

Effects

Action class

None: no approval rule names it, so it runs within its seat’s Permissions and Limits

Modes
  • try: Runs every check and returns the record as it would be; nothing is stored.
  • send: Returns a pending Action at once; Metric.defined fires when it is done.
  • do: Waits for the Action to finish and returns the record.
Idempotency

Only with a key: the same Idempotency-Key and input return the first Action, and the same key with other input returns 409.

Saved or shared

A Change that renames or removes an Event this Metric reads must map it to a new Event, or the Change is refused.

Emits

Metric.defined with { metric }

Analyst

Price

Free on your own account: the platform charges nothing for the call.

On each Venue

It acts on your own records and reaches no Venue, so every account answers the same way.

What try does

Runs every check the call meets and returns the record as it would be; nothing is stored, sent or posted.

Refuses when

GuardRefusesError
known-eventsRefuses a query that names an Event no Verb emits.invalid-input

When it waits

Returns in one response; nothing waits.

Example

In send mode the call returns its pending Action at once, and Metric.defined delivers the result.

You, to your agent
Define activation as a portfolio with 10 units imported and one rent
payment logged within 7 days.
Response, in send mode
{
  "mode": "send",
  "action": {
    "$id": "https://api.sb/leaseline.app/actions/action_Sd3kQ9vT2w",
    "operation": "Metric.define",
    "status": "pending",
    "reason": "running"
  }
}

To retry, send the same Idempotency-Key: the retry returns the first answer for $0. A new key reads again.
