title: Is there a way to programmatically know how many concurrent instances of a Lambda function are executing?
body: <p>Lets suppose, at a given time, several instances of a particular Lambda function have been invoked asynchronously,</p>
  
  <p>Then, is there a way to find how many <strong>active</strong> concurrent instances of the Lambda function are currently running? </p>
  
  <p>In the account level metrics in the Dashboard we can find the number of concurrent executions. Also, I think for each new Lambda container creation, Cloudwatch creates a new Log Stream for the Lambda function. Maybe it is possible to somehow use those.</p>
  
  <p>But I was wondering if there exists a different way to get these numbers programmatically, for example like using <code>boto3</code> api etc.?</p>
