+# Amazon ECS on EC2 cluster monitoring
+
+This example demonstrates how to monitor your Amazon Elastic Container Service on EC2
+(Amazon ECS) cluster with the Observability Accelerator's ECS monitoring module
+
+The module collects Prometheus metrics from tasks running on ECS and sends it to Prometheus using AWS Distro for OpenTelemetry Collector (ADOT).
+You can either run the collector as a sidecar or deploy the collector as its own ECS service for entire cluster.
+ECS tasks with Prometheus endpoints are discovered using extension
+[ecsobserver](https://github.com/open-telemetry/opentelemetry-collector-contrib/blob/main/extension/observer/ecsobserver/README.md).
+(Unlike EKS, there is no builtin discovery for ECS inside prometheus)
+
+Additionally, you can optionally collect custom Prometheus metrics from your applications running
+on your ECS cluster.
+
+## Prerequisites
+
+!!! note
+    Make sure to complete the [prerequisites section](https://aws-observability.github.io/terraform-aws-observability-accelerator/concepts/#prerequisites) before proceeding.
+
+## Available Samples for various Worklods
+Make sure to update your exisitng Application Task Definitions based on the workload type :-
+
+#### 1. [Java/JMX workload for ECS Clusters](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/ContainerInsights-Prometheus-Sample-Workloads-ECS-javajmx.html)
+#### 2. [NGINX workload for Amazon ECS clusters](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/ContainerInsights-Prometheus-Setup-nginx-ecs.html)
+#### 3. [App Mesh workload](https://docs.aws.amazon.com/AmazonCloudWatch/latest/monitoring/ContainerInsights-Prometheus-Sample-Workloads-ECS-appmesh.html)
+
+## Setup
+
+#### 1. Add the ECS Monitoring Module to your exisitng ECS CLuster
+
+```
+module "ecs_monitoring" {
+  source                = "../../modules/ecs-monitoring"
+  aws_ecs_cluster_name  = module.ecs_cluster.cluster_name
+  task_role_arn           = module.ecs_cluster.task_exec_iam_role_arn
+  execution_role_arn      = module.ecs_cluster.task_exec_iam_role_arn
+
+  depends_on = [
+    module.ecs_cluster
+  ]
+}
+```
+
+## Deploy
+
+Simply run this command to deploy the example
+
+```bash
+terraform apply
+```
+

+## Setup
+#### 1. Download sources and initialize Terraform¶
+
+```
+git clone https://github.com/aws-observability/terraform-aws-observability-accelerator.git
+cd terraform-aws-observability-accelerator/examples/ecs-cluster-with-vpc
+terraform init
+```
+
+#### 2. AWS Region¶
+Specify the AWS Region where the resources will be deployed:
+
+```
+export TF_VAR_aws_region=xxx
+```
+
+#### 3. Terraform Plan to validate the changes/updates
+
+```
+terraform plan
+```
+
+## Deploy
+
+Simply run this command to deploy the example
+
+```bash
+terraform apply
+```

+# ECS Cluster w/ EC2 Autoscaling
+
+Configuration in this directory creates:
+
+- ECS cluster using EC2 autoscaling groups
+- Autoscaling groups with IAM instance profile to be used by ECS cluster
+- Example ECS service that utilizes
+  - Mounts a host volume into the container definition
+  - Load balancer target group attachment
+  - Security group for access to the example service
+
+## Usage
+
+To run this example you need to execute:
+
+```bash
+$ terraform init
+$ terraform plan
+$ terraform apply
+```
+
+Note that this example may create resources which will incur monetary charges on your AWS bill. Run `terraform destroy` when you no longer need these resources.
