Machine learning

I am beginner in the Machine learning module in ES
i created single metric job and started it
it creates results
but I dont see that the job continues to run each 15 minutes or so and create new results
what do I miss?

You missed the button in the setup:

If you forget to click that button during the setup, no worries, just go to the jobs screen and click on the start button to start the datafeed:

and select "no end time"
