Logging Using awslogs Log Driver in Amazon ECS


Monitoring and logging can be as important as developing and deploying applications. Imagine managing an enterprise-level distributed application that runs on hundreds of containers. You must place your containers cleverly on instances to achieve a certain level of resilience and performance. On top of that, you would want to have visibility into CPU and memory usage so you’ll have an idea which task/tasks are resource-hungry at a given time. You may also want to check the disk space of your instance and see if you still have enough storage for your application. Fortunately, monitoring distributed applications hosted in AWS has [...]
