AWS ELB

Elastic Load Balancing automatically distributes your incoming traffic across multiple targets, such as EC2 instances, containers, and IP addresses, in one or more Availability Zones.

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:

Requirements

Zabbix version: 7.4 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.

Required Permissions

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":"*"
        }
    ]
  }

Access Key Authorization

If you are using access key authorization, you need to generate an access key and secret key for an IAM user with the necessary permissions:

  1. Create an IAM user with programmatic access.
  2. Attach the required policy to the IAM user.
  3. Generate an access key and secret key.
  4. Use the generated credentials in the macros {$AWS.ACCESS.KEY.ID} and {$AWS.SECRET.ACCESS.KEY}.

Assume role authorization

For using assume role authorization, add the appropriate permissions to the role you are using:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Action": "sts:AssumeRole",
            "Resource": "arn:aws:iam::{Account}:user/{UserName}"
        },
        {
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "elasticloadbalancing:DescribeTargetGroups"
            ],
            "Resource": "*"
        }
    ]
}

Trust Relationships for Assume Role Authorization

Next, add a principal to the trust relationships of the role you are using:

{
  "Version": "2012-10-17",
  "Statement": [
    {
      "Effect": "Allow",
      "Principal": {
        "AWS": "arn:aws:iam::{Account}:user/{UserName}"
      },
      "Action": "sts:AssumeRole"
    }
  ]
}

Set the following macros: {$AWS.ACCESS.KEY.ID}, {$AWS.SECRET.ACCESS.KEY}, {$AWS.STS.REGION}, {$AWS.ASSUME.ROLE.ARN}.

Note: If you set the {$AWS.ASSUME.ROLE.AUTH.METADATA} macro to true and set the macros {$AWS.STS.REGION} and {$AWS.ASSUME.ROLE.ARN}, the Zabbix server or proxy will attempt to retrieve the role credentials from the instance metadata service. This means that the Zabbix server or proxy must be running on an AWS EC2 instance with an IAM role assigned that has the necessary permissions. This approach is recommended when running Zabbix inside an AWS EC2 instance with an IAM role assigned, as it simplifies credential management.

Role-Based Authorization

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-->>"
        },
        {
            "Sid": "VisualEditor1",
            "Effect": "Allow",
            "Action": [
                "cloudwatch:DescribeAlarms",
                "cloudwatch:GetMetricData",
                "elasticloadbalancing:DescribeTargetGroups",
                "ec2:AssociateIamInstanceProfile",
                "ec2:ReplaceIamInstanceProfileAssociation"
            ],
            "Resource": "*"
        }
    ]
}

Trust Relationships for Role-Based Authorization

Next, add a principal to the trust relationships of the role you are using:

{
    "Version": "2012-10-17",
    "Statement": [
        {
            "Effect": "Allow",
            "Principal": {
                "Service": [
                    "ec2.amazonaws.com"
                ]
            },
            "Action": [
                "sts:AssumeRole"
            ]
        }
    ]
}

Note: Using role-based authorization is only possible when you use a Zabbix server or proxy inside AWS.

Set the macros: {$AWS.AUTH_TYPE}, {$AWS.REGION}, and {$AWS.ELB.ARN}.

For more information about managing access keys, see official AWS documentation.

See the section below for a list of macros used for LLD filters.
