This page describes how to create artifacts for the Analytics Project. It contains the following sections:

WSO2 CEP uses Execution Plans to store event processing logic. An Execution Plan is bound to an instance of the Siddhi complex event processing runtime, which is responsible for the actual processing of the events. The event processor allows users to configure multiple Execution Plans where by providing multiple isolated event processing environments per Execution Plan. A typical Execution Plan consists of a set of queries and related input and output Event Streams.Definitions of the event streams are stored in the file system as deployable artifacts in the  <CARBON _HOME>/repository/deployment/server/executionplans/ directory as .siddhiql files. More.

Creating a new Execution-plan

...

1. Open the Developer Studio Dashboard (click Developer Studio > Open Dashboard) and click Execution-plan in the Analytics category.
2. Select Import Execution-plan and click Next.
3. Type a unique name for the Execution-plan.
4. Specify the execution-plan file by typing its full path name or clicking Browse and navigating to the file.
5. In the Save Execution-plan In field, specify an existing Analytics project in your workspace where you want to save the execution-plan, or click Create new Project to create a new Analytics project and save the execution-plan there.
6. Click Finish. The execution-plan is created in the execution-plan folder under the Analytics project you specified, and the execution-plan is open in the editor.

Creating a Stream

Events are the lifeline of WSO2 CEP/DAS. They not only process data as events, but also interact with external systems using events. Event is a unit of data, and an event stream is a sequence of events of a particular type. The type of events can be defined as an event stream definition.Definitions of the event streams are stored in the file system as deployable artifacts in the  <CARBON _HOME>/repository/deployment/server/eventstreams/ directory as .json files. More

Creating a new Stream

Follow these steps to create a new stream. Alternatively, you can import an existing stream.

...

1. Open the Developer Studio Dashboard (click Developer Studio > Open Dashboard) and click Stream in the Analytics category. 
2. Select Import Stream and click Next. 
3. Type a unique name for the Stream. 
4. Specify the stream file by typing its full path name or clicking Browse and navigating to the file. 
5. In the Save Stream In field, specify an existing Analytics project in your workspace where you want to save the stream, or click Create new Project to create a new Analytics project and save the stream there. 
6. Click Finish. The stream is created in the stream folder under the Analytics project you specified, and the stream is open in the editor.

Creating a Publisher

Event publishers publish events via various transport protocols.Event publisher configurations are stored in the file system as deployable artifacts in the  <CARBON _HOME>/repository/deployment/server/eventpublishers/ directory as .xml files. More

Creating a new Publisher

Follow these steps to create a new publisher. Alternatively, you can import an existing publisher.

1. Open the Developer Studio Dashboard (click Developer Studio > Open Dashboard) and click Publisher in the Analytics category.
2. Select Create New Publisher and click Next.
3. Type a unique name for the Publisher.
4. Do one of the following:
• • To save the publisher in an existing Analytics project in your workspace, click Browse and select that project.
  • To save the publisher in a new Analytics project, click Create new Project and create the new project.
5. Click Finish. The publisher is created in the publisher folder under the Analytics project you specified, and the publisher is open in the editor.

Importing a Publisher 

Follow these steps to import an existing publisher from an XML file into an Analytics project. Alternatively, you can create a new publisher.

1. Open the Developer Studio Dashboard (click Developer Studio > Open Dashboard) and click Publisher in the Analytics category.
2. Select Import Publisher and click Next.
3. Type a unique name for the Publisher.
4. Specify the publisher file by typing its full path name or clicking Browse and navigating to the file.
5. In the Save Publisher In field, specify an existing Analytics project in your workspace where you want to save the publisher, or click Create new Project to create a new Analytics project and save the publisher there.
6. Click Finish. The publisher is created in the publisher folder under the Analytics project you specified, and the publisher is open in the editor.

Creating a Receiver

Events are received by WSO2 CEP/DAS server using event receivers, which manage the event retrieval process. Event receiver configurations are stored in the file system as deployable artifacts in the  <CARBON _HOME>/repository/deployment/server/eventreceivers/ directory as .xml files. More

Creating a new Receiver

Follow these steps to create a new receiver. Alternatively, you can import an existing receiver.
