How to enable JMX metrics for ECS / Fargate ?

Question

We have a docker image with an undertow server deployed in ECS / Fargate.
How do I get the CloudWatch metrics -> Container Insigths -> Performance monitoring -> ECS Prometheus Java/JMX ?

Despite many manipulations, the dashboard remains hopelessly empty.

Answer

Hi,
* First you need to collect metrics from a sample Prometheus workload for Amazon ECS, you must be running Container Insights in the cluster. https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/deploy-container-insights-ECS.html
* Then you need to Java/JMX workload for Amazon ECS clusters, here an example of the process: https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/ContainerInsights-Prometheus-Sample-Workloads-ECS-javajmx.html

Here an interesting blog post that should cover what do you need https://aws.amazon.com/blogs/mt/monitor-and-scale-your-amazon-ecs-on-aws-fargate-application-using-prometheus-metrics/
