Using the template

Follow the procedure below to use the previously created SensorDataAnalysis template in different scenarios.

1. Log in to the management console using the following URL.
    https://<CEP_HOST>:<CEP_PORT/carbon/
2. Click Main, and then click Template Manager under the Manage menu. The following dashboard home page appears with the available domains as shown below.
   
3. Select the relevant domain to configure the defined template (in this example it is SensorDataAnalysis). This opens the Deployed Scenarios page.
4. Click Create New Scenario to add a new scenario to the selected domain. This opens the Edit Scenario page.
   

   1. Enter values in the Edit Scenario page as follows.

      Field	Value	Notes
      Scenario Type	SensorAnalytics	This is the template created by following the instructions in Configuring a Template for Template Manager.
      Scenario Name	SensorAnalytics
      Description	Calculate maximum and average temperature values.

      Enter values for the configurable parameters as shown below. 

      Configurable Parameters	Value
      Time(Mins)	1
      Sensor Type Name	temperature

5. Click Add Scenario. A pop-up message appears to inform you that the configuration is successfully saved. Close this message. The scenario you configured is displayed in the Deployed Scenarios page as follows.
   
   You can edit or delete this scenario by clicking the relevant link under Actions.

   Info

   In this example, the scenario gets deployed at this stage because no stream mapping is configured in the default SensorAnalytics template used. If you have configured stream mapping for your template, you are redirected to the Stream Mapping page when you click Add Scenario. Select an appropriate predefined stream from the list for the Mapped From: Stream Name field. This expands the page to display the Attribute Mapping section as demonstrated below. Map attributes as required and click Save Mapping.

   Once this configuration is successfully completed, the artifacts included in the template are deployed in WSO2 CEP. You can view the event flow for the template artifacts by logging into the WSO2 CEP Management Console, and clicking Main ∫=> Flow where it is displayed as follows.
   

6. In order to access the dashboard with templated gadgets, in the Main tab, the WSO2 CEP Management Console, click Main and then click Analytics Dashboard.
7. Enter your username and password, and then click Login.
8. Select view mode in to open the Analytics Dashboard. Log in with your credentials. The dashboard named analytics-temperature-dashboard from the Dashboards menu as shown below.

9. In order to simulate data for the created scenario, you can use the event simulator functionality to send multiple events using file utilizing default event simulator file(event.csv) which comes with CEP. 
10. Upon successful simulation, data will be published to the deployed dashboard as shown below.

11. To simulate data in order to view statistics in the analytics-temperature-dashboard dashboard, do the following. For more information, see Sending Multiple Events Using a File.
    
    1. In the WSO2 CEP Management Console, click Tools and then click Event Simulator to open the Event Stream Simulator page.

    2. Click Configure for the events.csv file to open the Event Mapping Configuration dialog box. Enter the following values in this dialog box.

       Parameter	Value
       Select the target event stream	org.wso2.event.temperature.stream:1.0.0
       Field delimiter	,

       Click Configure and then click OK to close the message that appears to confirm that the configuration is successful.

    3. Click Play to simulate the event flow.
