title: AWS Lambda Reserved and Unreserved Concurrency Alarm
body: <p>In our set up, we have lots of AWS Lambda functions, developed by different teams. Some of the them have set a reserved concurrency. This eats out of the total concurrency of the account (1000). </p>
  
  <p>Is there a way to monitor or set an alarm that is triggered when the unreserved currency drops below specific level? </p>
  
  <p>This would be helpful to proactively do something to alleviate the issue and reduce failures.</p>
