title: How do I add Dataflow memory usage to Stackdriver?
body: <p><strong>Problem:</strong></p>
  
  <p>We want to understand the memory usage of our Cloud Dataflow job, preferably per worker/VM. We'd like to add this to Stackdriver, but it seems we can only add cpu usage and disk I/O metrics.</p>
  
  <p><strong>Question:</strong></p>
  
  <p>Is there a way to add Cloud Dataflow memory usage to Stackdriver? </p>
