Predict future behavior of a time series Added in 6.1.0

POST /_ml/anomaly_detectors/{job_id}/_forecast

Forecasts are not supported for jobs that perform population analysis; an error occurs if you try to create a forecast for a job that has an over_field_name in its configuration. Forcasts predict future behavior based on historical data.

Path parameters

  • job_id string Required

    Identifier for the anomaly detection job. The job must be open when you create a forecast; otherwise, an error occurs.

Query parameters

  • duration string

    A period of time that indicates how far into the future to forecast. For example, 30d corresponds to 30 days. The forecast starts at the last record that was processed.

  • expires_in string

    The period of time that forecast results are retained. After a forecast expires, the results are deleted. If set to a value of 0, the forecast is never automatically deleted.

  • max_model_memory string

    The maximum memory the forecast can use. If the forecast needs to use more than the provided amount, it will spool to disk. Default is 20mb, maximum is 500mb and minimum is 1mb. If set to 40% or more of the job’s configured memory limit, it is automatically reduced to below that amount.
