Neuron
Stream Scan table
The NeuronEX data processing module can receive data from the NeuronEX data collection module through Neuron
type data sources and process and analyze them through rules.
In NeuronEX Data Processing -> Sources, under the Stream tab, NeuronEX has configured the Neuron
type data source neuronStream by default.
To send data from the NeuronEX data collection module to neuronStream, you need to add and subscribe the driver data to the DataProcessing
node under the NeuronEX Data collection -> North Apps tab, as shown in the following figure:
Then, users can directly select neuronStream
as the data source in Data Processing -> Rules -> Create Rule to create rules.
SELECT * FROM neuronStream
