THRESHOLD

Adds a THRESHOLD label to an anomaly if the metric is above a maximum threshold or below a minimum threshold. By default, the threshold is applied to the metric that was used for the detection. A different metric can be provided by passing an input current. The threshold rule will run on this metric.

Inputs

• The output of the detector. Labels are applied to the anomalies of this input.

{
  "sourcePlanNode": "anomalyDetector"
}

• Optional: a different side data input to perform threshold on

{
  "targetProperty": "current",
  "sourcePlanNode": "controlDataFetcher",
  "sourceProperty": "controlDataOutput"
}

Parameters

name	description	default value
component.min	If metric <= min, label the anomaly.	-1 (special value - no minimum)
component.max	If metric >= max, label the anomaly.	-1 (special value - no maximum)
component.valueName	Optional. The name of the metric. Used in the label: "{ValueName} bigger than {max}"	Value
component.timestamp	Optional. If a side data input is used, name of the time index column.	timestamp
component.metric	Optional. If a side data input is used, name of the column to use for thresholding.	value

Example

• Without side input

{
  "name": "root",
  "type": "PostProcessor",
  "params": {
    "type": "THRESHOLD",
    "component.ignore": "true",  # filter anomaly in notifications an ui by default
    "component.min": "100",
    "component.max": "10000000"
  },
  "inputs": [
    {
      "sourcePlanNode": "anomalyDetector"
    }
  ]
}

• With side input

    "component.min": "100",
    "component.max": "10000000",
    "component.valueName": "controlMetric", # customize label
    "component.timestamp": "ts",            # time column of the side input
    "component.metric": "sideMetric"        # column to threshold on in the side input
  },
