Timeseries Features DSLedit

Defines how time series data must be aggregated into features for learning and inference.

Features define how to aggregate numerical data from a measurement A measurement defines an object type in the data source:

  • For Elasticsearch data source, the measurement is not used. You can set the doc_type in config.yml data source settings. Default is doc if not set
  • For InfluxDB data source, the measurement is the series measurement name
  • For MongoDB data source, the collection is the series data collection

Accepted parameters to define model features are:


Name given to this feature


TSDB column name


TSDB table to fetch data


TSDB collection to fetch data


list of TSDB tag names and values that must be matched when fetching the data


An aggregation operator supported by the TSDB


A default float value to replace NaN values returned by the TSDB, or previous in order to fill the series with previous non-NaN value


low_high, low, or high according to the type of abnormal values to detect

The list below defines the aggregation operators can be used to define features. These values can be extracted by using numeric fields in the data source documents.


This version does not support feature generation by a provided script, nor extracting features from categories ie, non numeric fields.

The metric operators that are supported consist of: count, min, max, sum, avg, sum_of_squares, variance, and std_deviation.


This version supports the following additional operators with InfluxDB: derivative, integral, spread, mode, 5percentile, 10percentile, 90percentile, 95percentile, stddev
