I found the issue. In the latest Karpenter version metrics port is updated to 8080 from 8000. Datadog documentation has not updated this change. Helm/Binary: controller.METRICS_PORT default changed back to 8080

From documentation https://docs.datadoghq.com/integrations/karpenter/ Updating below fixed the issue.

"openmetrics_endpoint": "http://%%host%%:8080/metrics"

That is one of the problems but many metrics were also renamed and they will not work until this PR is released with Datadog agent: https://github.com/DataDog/integrations-core/pull/18448
