AWS ECS Monitoring

AWS ECS - Overview

Amazon Elastic Container Service (Amazon ECS) is a highly scalable, fast, container management service that makes it easy to run, stop, and manage Docker containers on a cluster. Amazon ECS lets you launch and stop container-based applications with simple API calls, allows you to get the state of your cluster from a centralized service, and gives you access to many familiar Amazon EC2 features.

Monitored Parameters

Go to the Monitors Category View by clicking the Monitors tab. Click on the ECS available under Amazon in the Cloud Apps section. Displayed is the Amazon ECS bulk configuration view distributed into three tabs:

Availability tab gives the availability history for the past 24 hours or 30 days.
Performance tab gives the health status and events for the past 24 hours or 30 days.
List view tab enables you to perform bulk admin configurations.

By clicking a monitor from the list, you'll be taken to the AWS ECS dashboard. It has 5 tabs:
