Hi Rumesh, Thank you for your interest. Currently there is not any API in Siddhi to retrieve information such as statistics. Deliverable of the project is to embed that functionality into Siddhi and develop an UI to visualize the information retrieved by that API. In high level at run-time Siddhi query is a collection Processors where each Processor consists of multiple Executors. So an event sent to Siddhi via an InputHandler will go though these Executors which will perform desired operations on the event. As of As starters you can check out Siddhi code[1], play with samples and get an understanding of Siddhi internals. However in CEP level we have both event flow and event statistics[2][3]. You can also have a look at them for reference. Feel free to ask if you need more details regarding the project.
