AWS elb metricset
Elastic Load Balancing publishes data points to Amazon CloudWatch for your load balancers and your back-end instances. This aws elb metricset collects these Cloudwatch metrics for monitoring purposes.
Some specific AWS permissions are required for IAM user to collect AWS ELB metrics.

The aws elb metricset comes with a predefined dashboard for classic ELB. For example:
- module: aws
period: 300s
metricsets:
- elb
access_key_id: '${AWS_ACCESS_KEY_ID:""}'
secret_access_key: '${AWS_SECRET_ACCESS_KEY:""}'
session_token: '${AWS_SESSION_TOKEN:""}'
# This module uses the aws cloudwatch metricset, all
# the options for this metricset are also available here.
elb metricset collects Cloudwatch metrics from classic ELB, application ELB and network ELB.
