Tell us about your request
Tast definition metadata should return full Docker Stats (https://docs.docker.com/engine/api/v1.30/#operation/ContainerStats)

Which service(s) is this request for?
Fargate, ECS

Tell us about the problem you're trying to solve. What are you trying to do, and why is it hard?
While trying to monitor my task with Datadog Agent, everything works fine with platform_version 1.3.0 , but when I upgrade to 1.4.0 , some metrics from task metadata endpoint disappear. When I go deeper in datadog agent code , it seems that the task metadata endpoint does not return anymore these values :

online_cpus

You could see a sample with a task definition metadata from 1.4.0 on the left and a task definiton metadata 1.3.0 on the right here

(on the other side we have network informations in 1.4.0 which is a nice feature :+1: )

Are you currently working around this issue?
We rollback to platform_version 1.3.0

Additional context
N/A

Hello @J-Mx ,

Thank you for reporting this, we have identified this as a bug in Fargate PV 1.4. We will work on addressing this and provide updates once it is resolved.

This is now fixed. Please relaunch tasks on PV1.4 to observe system_cpu_usage and online_cpus.

Hello @akshayram-wolverine ,

I relaunched my task on PV1.4.0 and saw the task metadata. But I still could not find some values such as precpu_stats. system_cpu_usage (not cpu_stats.system_cpu_usage).

Are there any plan to fix also it?

Here is my diff between PV1.3.0 and PV1.4.0 .
