Kubernetes: Can Dynatrace generate requests/limits recommendations ? (like does VPA Recommander)

Hello Dynatrace Community !

We use Kubernetes.

At the company I work for, the development teams struggle to define good requests/limits for their workloads.

Can Dynatrace generate requests/limits recommendations for k8s workloads ? (like does VPA Recommander)

Here an example of some recommendations returned by VPA Recommander.

recommendation:
  containerRecommendations:
  - containerName: nginx
    lowerBound:
      cpu: 40m
      memory: 3100k
    target:
      cpu: 60m
      memory: 3500k
    upperBound:
      cpu: 831m
      memory: 8000k

I didn't found a Dynatrace feature that accomplish that specifically.

I can create a custom Dynatrace dashboard based on cpu/memory metrics real usage, with some logic that I would define myself (e.g. to ignore extreme values), but I would prefer to use an existing feature already renowned to work well.

Thank you very much !

Frank B.
