Workload Scheduler bluemix

I have a PHP application that I have hosted in bluemix which just writes current time in a text file (sample application). Now I want to schedule it to run this application every 5 minutes on everyday using Workload Scheduler.

So I created this service and I included it and clicked "Launch Application Lab" on the Workload Scheduler from the dashboard. I tried creating step for this link below.

http://dmrt.au-syd.mybluemix.net/

but I couldn't able to run this page on schedule. Need help on how to do it in Application Lab

This is the step that I have followed:

1) Clicked on the Application Lab

2) Created a new process and have set valid from/to.

3) Created trigger (next tab) . I have taken the screenshot and attached it as link. Please refer from here.

4) Now in Steps tab I exactly don't know what to choose from the drop down for the bluemix link that I have shared so that I can run that page in schedule.

It would be a great help if anyone can tell me the procedure or steps that need to be followed.

Here are the steps to follow:

• Create a process library (Click "New" under "Process Library")
• Create a new process (select the process library you just created and click "New"
• Create a new step (Select the process, click "Step" and then click "New"). A pop-up appears

• Define a restful step.

  Select a step of type "Restful"

  Select your agent (you should have only one)

  Click the "Action" tab

  Fill the "Service URI" field with http://dmrt.au-syd.mybluemix.net

  Click OK

The panel should look like this: See image

• Create the trigger

  Select trigger

  Click New

  In the "Repeat every" field set 5 minutes

• Select the process and click "Enable"

This should work!
