AWS ELB Application Load Balancer by HTTP
Overview
Please scroll down for AWS ELB Network Load Balancer by HTTP.
The template is designed to monitor AWS ELB Application Load Balancer by HTTP via Zabbix, and it works without any external scripts. Most of the metrics are collected in one go, thanks to Zabbix bulk data collection.
This template uses the GetMetricData CloudWatch API calls to list and retrieve metrics. For more information, please refer to the CloudWatch pricing page.
Additional information about metrics and API methods used in the template:
- Full metrics list related to AWS ELB Application Load Balancer
- DescribeAlarms API method
- DescribeTargetGroups API method
Requirements
Zabbix version: 6.4 and higher.
Tested versions
This template has been tested on:
- AWS ELB Application Load Balancer with Target Groups by HTTP
Configuration
Zabbix should be configured according to the instructions in the Templates out of the box section.
Setup
The template gets AWS ELB Application Load Balancer metrics and uses the script item to make HTTP requests to the CloudWatch API.
Before using the template, you need to create an IAM policy with the necessary permissions for the Zabbix role in your AWS account. For more information, visit the ELB policies page on the AWS website.
Add the following required permissions to your Zabbix IAM policy in order to collect AWS ELB Application Load Balancer metrics.
{
"Version":"2012-10-17",
"Statement":[
{
"Action":[
"cloudwatch:DescribeAlarms",
"cloudwatch:GetMetricData",
"elasticloadbalancing:DescribeTargetGroups"
],
"Effect":"Allow",
"Resource":"*"
}
]
}
If you are using role-based authorization, set the appropriate permissions:
{
"Version": "2012-10-17",
"Statement": [
{
"Effect": "Allow",
"Action": "iam:PassRole",
"Resource": "arn:aws:iam::<<--account-id-->>:role/<<--role_name-->>"

"ec2:ReplaceIamInstanceProfileAssociation"
],
"Resource": "*"
}
]
}
Set the macros {$AWS.AUTH_TYPE}
, {$AWS.REGION}
, and {$AWS.ELB.ARN}
. If you are using access key-based authorization, set the macros {$AWS.ACCESS.KEY.ID}
and {$AWS.SECRET.ACCESS.KEY}
