Mackerel supports obtaining and monitoring each Load Balancer metric of Elastic Load Balancing in AWS Integration. This page contains details regarding the Application Load Balancer (ALB). When integrating with AWS Integration, billable targets are determined using the conversion 1 ALB = 1 Micro Host. In addition to this, depending on the number of metrics retrieved, you may be charged for exceeding the maximum number of metrics per micro host.
Please refer to the following page for AWS Integration configuration methods and a list of supported AWS services.
AWS Integration
In addition, you can take a look at the help pages for other supported Load Balancers; NLB and ELB (CLB).
Obtaining metrics
The metrics obtainable with AWS Integration’s ALB support are as follows. For Metric explanations, refer to the AWS help page.
The maximum number of metrics obtainable is 18 + 13 × (number of target groups).

Graph per Target Group
Since there can be multiple target groups per load balancer in Application Load Balancer, each metric is grouped as follows. The metric name’s TARGET_GROUP_NAME will contain the name of the target group.
| Graph name | Metric | Metric name in Mackerel | Unit | Statistics |
|---|---|---|---|---|
| Request Count per Target Group | RequestCount | alb.request_per_group.TARGET_GROUP_NAME.count | integer | Sum |
| Request Average per Target | RequestCountPerTarget | alb.request_average_per_target.TARGET_GROUP_NAME.average | float | Sum |
