JSON Threshold Evaluator - Ironstream_Hub - 1.3.2

This process allows you to pass on only those JSON records that breach a user-defined numeric threshold. You can delay sending continual threshold breaches for a number of seconds by setting an optional parameter to a value greater than zero.

If a JSON record without the delay option breaches the threshold described in these parameters, it is passed to the next node in the pipeline. If not, it is not passed on.

If a JSON record with the delay option breaches the threshold described in these parameters it is passed to the next node in the pipeline after that delay time, if the threshold is breached. Further breaches are passed on immediately until the threshold is no longer breached. If a value does not breach the threshold, it is not passed on.

If a JSON record does not contain the key set in PropertyName, the record will not be passed on. A warning will be written to the user log file.

1. To add JSON Threshold Evaluator, click JSON Threshold Evaluator in Add Process window. The canvas updates immediately. The orange icon identifies that it is not valid, or not complete. The green ‘check’ icon is no longer present against the Target. This identifies that the pipeline is not complete, or not correct.
