title: Understanding AWS Glue detailed job metrics
body: <p>Please see the attached screen shot of the CPU Load: Driver and Executors. It looks fine in the first 6 minutes, multiple executors are active. But after 6 minutes the chart only shows the Executor Average and Driver lines. When I put the mouse on the line, there are no usage data for all 17 executors. Does that mean all the executors are inactive after 6 minutes? How the Executor Average is calculated?</p>
  
  <p>Thank you.</p>
