Publish JVM metrics via Hadoop metrics URL: https://github.com/apache/hadoop/pull/994#issuecomment-507479341 > @elek Can this be done for HDDS client as well? Sure. I added it to the freon. For simple `ozone sh` it's more tricky as metrics generates additional logging which may break the existing tests (and can be confusing), but at freon it's no problem as it's already logging a lot. And metrics is more useful for freon than shell anyway.... ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
