Amazon Elastic Container Service Monitoring Integration
Amazon Elastic Container Service lets you run Dockerized applications on a managed clusters of EC2 instances with ease. With Site24x7's integration, you can now monitor utilization stats at both the cluster-level and service-level for both the EC2-launch type and Fargate-launch type.
Use case
Amazon ECS is a highly scalable container management service. Consider a use case where you have a container running in an ECS monitor. When you integrate your Amazon ECS with Site24x7, then ECS Cluster and ECS Cluster Service monitors will be created. If your cluster monitor is down or facing an issue, you can identify and track the issue with the alerts configured.
Benefits of the integration between Site24x7 and Amazon ECS
Site24x7's integration with Amazon Elastic Container Service (ECS) enables you to monitor your Amazon ECS at cluster, container, services, and task level.
With the integration between Site24x7 and Amazon ECS, you can:
- Monitor your resources with multiple metrics.
- Configure thresholds and receive alerts when your cluster or container instance is down.
- Get a detailed overview of services, tasks, and container instances along with container insight details in the form of graphs.
Prerequisites
- For EC2 launch type, please make sure the Amazon ECS container instances are running the container agent version 1.4.0 or higher. Also, ensure the IAM role assigned to the container instances during launch has the permission ecs:StartTelemetrySession.
- For Fargate launch type, the CloudWatch CPU and memory utilization metrics are collected automatically.
Setup
- If you haven't done it already, please provide Site24x7 access to your AWS account by either creating an IAM User or IAM Role. Learn more
- On the Integrate AWS Account page, please make sure the ECS Cluster checkbox is selected in the Services to be discovered field. Learn more.
Permissions
Please make sure the following read-level actions are present in the IAM policy assigned to the IAM User or IAM Role created for Site24x7. Learn more.
- "ecs:ListServices",
- "ecs:ListAccountSettings",

Poll frequency
Aggregated ECS metric data is collected as per the poll frequency set (1 minute to a day). Learn more.
Licensing
- Each ECS cluster is considered a basic monitor.
- Each ECS service running in your cluster is considered a basic monitor.

You can view the following data in Site24x7's ECS monitoring interface:
Summary
Get an overview of cluster level metrics with time series charts in the Summary tab. These charts provide information about CPU Utilization, CPU Reservation, Memory Reservation, and Memory Utilization. The tab provides overall statistics, such as number of services, pending tasks, running tasks, and container instances created in a cluster.
Container Insights
Container Insights collects and analyzes metrics and logs from your containerized applications and microservices. When you configure Container Insights for your integrated monitor, you can obtain information about Fargate/EC2 level metrics, such as CPU Utilization, CPU Reservation, Memory Reservation, Memory Utilization, Network Traffic, Storage Traffic, and Container Instances in a time series chart.
Services
Services are used to run a certain number of task definitions simultaneously in an ECS Cluster. It lists the number of services in the cluster and its configuration details.The time series graph for service level CPU Utilization, Memory Utilization, and Number of Tasks with pending and running statuses are displayed.
Task Definition
A task definition is required to run Docker containers in Amazon ECS. The Task Definition tab shows a list of task definitions used to create tasks in a particular ECS cluster.
Instance
The Instance tab displays the list of container instances in the ECS Cluster and information about instances, like Memory Available, CPU Available, Pending Tasks, and Running Tasks.
Monitored Resources
The Monitored Resource tab displays the EC2 instances associated with the ECS Cluster.
