Does Datadog support AWS ALB (Application Load Balancer)?

Yes! Our AWS integration was updated in August 2016 to support the new Application Load Balancer metrics published by AWS Cloudwatch.

Both Application and Classic ELBs have their metrics reported in Datadog under the namespace "elb".

For instance, "aws.elb.active_connection_count" is the Datadog metric name corresponding to the Cloudwatch metric (ALB only) named "ActiveConnectionCount".
