title: How can I create a custom metric watching EFS metered size in AWS Cloudwatch?
body: <p>Title pretty much says it all - Since the EFS metered size (usage) ist not a metric that I can use in Cloudwatch, I need to create a custom metric watching the last metered file size in EFS. </p>
  
  <p>Is there any possiblity to do so? Or is there maybe a even better way to monitore the size of my EFS?</p>
