@Huang-Wei this issue is due to some metric name upgrades specific to OpenShift. We have made some changes in load watcher so it supports both OpenShift and Kubernetes, should we push an update on the versions of load watcher for Trimaran?

[Huang-Wei]

should we push an update on the versions of load watcher for Trimaran?

Yes, please. And come up with a release note detailing what metrics are both supported.
