Amazon Elastic Kubernetes Service Monitoring Integration
Amazon Elastic Kubernetes Service (Amazon EKS) enables you to easily deploy, manage, and scale containerized applications using Kubernetes on AWS. With Kubernetes you can automate the deployment, scaling, and management of containerized applications at scale.
With Site24x7's integration, monitor your Amazon EKS at the cluster, node, and namespace level to achieve full-stack visibility into your Amazon EKS.

Setup and Configuration
1. If you haven't already, enable access to your AWS resources between your AWS account and Site24x7's AWS account by either:
- Creating Site24x7 as an IAM user.
- Creating a cross-account IAM role. Learn more
2. On the Integrate AWS Account page, check the box next to Amazon EKS. Learn more
Prerequisite
- Install the Container Insights on Amazon EKS. Learn more
Policy and Permissions
Site24x7 uses various Amazon EKS APIs to collect information about your clusters. Assign the AWS Managed policy ReadOnlyAccess to the Site24x7 entity (IAM user or IAM role) to help Site24x7 collect metrics and metadata. If you want to assign a custom policy, please make sure the following read-level actions are present in the policy JSON. Learn more
- "eks:DescribeCluster",
- "eks:ListClusters",
- "cloudwatch:ListMetrics"
Polling Frequency
Site24x7 collects metric data on your clusters, namespace and nodes as per the poll frequency set, ranging from one minute up to one day. Learn more
