This section explains each of the properties in the configuration blade.
Collection
This associates the Agent to a specific Collection and defaults to that of the current Data Stream.
Method
The method options are:
Forward
Backward
Sampling Frequency
The sampling frequency of the input payload, measured in Hz (applies to Forward method only). For example, the sampling frequency is 100Hz if the input payload is sampled 100 times per second.
Before configuring the Transformation, please ensure that its input endpoint is connected to a parent Agent which will be sending data to it.
A single input mapping is required, either for the Real or Imaginary value, as input to the FFT function.
Real (Double)
The column or attribute of the input payload that contains the Real value.
Imaginary (Double)
The column or attribute of the input payload that contains the Imaginary value.
Input
This endpoint is used to receive data from the parent Agent on which to apply the FFT function: either the Real or Imaginary value. The algorithm requires that the length of the input payload be a power of 2 (e.g. 2, 4, 8, 16, 32, etc.) with a maximum length of 2^14 (16,384) supported.
Output
The Agent publishes the resulting events to this endpoint with 4 attributes:
Real: The real number component of the transformed output
Imaginary: The imaginary (complex) number component of the transformed output
Magnitude: The calculated combined magnitude of the real and imaginary components
Frequency: The frequency scaling of the output value
Error
Errors encountered during the execution of this Agent will be published on this endpoint.
