Sample 0119 - Output Events at Defined Time Intervals

Introduction

This sample demonstrates how to set up an execution plan to process events of one stream and forward the processed events to two other streams. This sample uses the Event simulator for inputs and the logger publisher for logging the outputs to the CEP console.

Prerequisites

See Prerequisites in the CEP Samples Setup page.

Building the sample

Start the WSO2 CEP server with the sample configuration numbered 0119. For instructions, see Starting sample CEP configurations. This sample configuration does the following:

Executing the sample

Follow the steps below to execute the sample.

1. Log into the CEP Management Console.

2. Click on the Tools tab and then click Event Simulator to open the Event Stream Simulator page. A file named events.csv containing sample data is displayed in the Send multiple events section as follows. Click Play to start sending events to the CEP from this file.
   
   As a result, the following output is displayed in the CLI.
