 CI Visibility supports Infrastructure metrics for the Kubernetes executor. For this, it is necessary to have the Datadog Agent monitoring the Kubernetes Gitlab infrastructure. See [Install the Datadog Agent on Kubernetes][1] to install the Datadog Agent in a Kubernetes cluster.
 
+Due to limitations in the Datadog Agent, jobs shorter than the minimum collection interval of the Datadog Agent might not always display infrastructure correlation metrics. To adjust this value, see [Datadog Agent configuration template][2] and adjust the variable `min_collection_interval` to be less than 15 seconds.
