How to write eKuiper rule SQL to fulfill my requirements
Please refer to the eKuiper Docs
The Neuron eKuiper node stays disconnected after eKuiper started successfully
Make sure you create rules that use the eKuiper neuron source. eKuiper will defer the connection until the rules are started.
How do I know eKuiper collects data from Neuron successfully?
Check that the data-stream-processing node is connected, and subscribe to some south nodes.
Check that the data-stream-processing node actually collects data using the dashboard metrics panel.
