Datadog monitoring of ECS Clusters

Question

I am coming up with a new dashboard in our datadog account to monitor our ecs clusters.

There are two sides that we want to have visibility into 
- the ec2 machines (infrastructure)
- the ecs tasks (application)

I'm struggling with getting everything set up and I can't tell where is the best place to ask for support.

**Monitoring the infrastructure**

I would like to monitor the following things, am I looking at the correct metrics:

(1) Number of ec2 instances per ecs cluster - `ecs.containerinsights.container_instance_count`

(2) % of CPU reserved / allocated to the tasks running on the ec2 machine -
`aws.ecs.cluster.cpureservation`

(2) % of CPU actually being used on the ec2 machine -
`aws.ecs.cluster.cpuutilization`

(3) % of memory reserved / allocated to the tasks running on the ec2 machine -
`aws.ecs.cluster.memoryreservation`

(4) % of memory actually being used on the ec2 machine -
`aws.ecs.cluster.memoryutilization`

(5) % of disk used for the ebs volumes -

`aws.ecs.cluster.cpureservation`

Hello,

Simple way to set up Datadog monitoring for your ECS clusters.

**For The EC2 Instances**

**Number of EC2 Instances**

* Metric: aws.ecs.cluster.container_instance_count.

**CPU and Memory Utilization**

* Metrics: aws.ec2.cpuutilization and aws.ec2.memoryutilization.

**Disk Usage**

* Metric: Use aws.ec2.diskutilization or set up custom metrics if needed.

**For The ECS Tasks**

**Task CPU and Memory Utilization**

* Metrics: aws.ecs.task.cpuutilization and aws.ecs.task.memoryutilization.

**Steps to Implement**

**Integrate Datadog with AWS CloudWatch**

* Follow Datadog’s integration guide to connect with CloudWatch.

**Create Dashboards**

* Use Datadog to create dashboards displaying the metrics mentioned above.

**Set Up Alerts**

* Configure alerts in Datadog for high CPU, memory usage, or disk space issues.
