Elastic Load Balancing (ELB) is an AWS service used to dispatch incoming web traffic from your applications across your Amazon EC2 backend instances, which may be in different availability zones. ELB helps ensure a smooth user experience and provide increased fault tolerance, handling traffic peaks and failed EC2 instances without interruption.
Datadog collects metrics and metadata from all three flavors of Elastic Load Balancers that AWS offers: Application, Classic, and Network Load Balancers.
If you haven’t already, set up the Amazon Web Services integration first.
In the AWS integration tile, ensure that ELB is checked under metric collection. Check also ApplicationELB checkbox for Application ELB metrics, and the NetworkELB checkbox for Network ELB metrics.
Add those permissions to your Datadog IAM policy in order to collect Amazon ELB metrics:
elasticloadbalancing:DescribeLoadBalancers: List ELBs, add additional tags and metrics.elasticloadbalancing:DescribeTags: Add custom ELB tags to ELB metrics.elasticloadbalancing:DescribeInstanceHealth: Add state of your instances.For more information on ELB policies, review the documentation on the AWS website.
Install the Datadog - AWS ELB integration.
Enable the logging on your ELB first to collect your logs. ELB logs can be written in a AWS S3 bucket and consumed by a Lambda function. For more information, refer to the AWS documentation
Set interval to 5 minutes and define your s3 buckets:
Once the lambda function is installed, there are two ways to collect your ELB logs:
Object Created (All) then click on the add button.
Once done, go in your Datadog Log section to start exploring your logs!
