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 |
