      Description

      Currently the metrics infrastructure is available only to the backend code, but we should be able to easily expose metrics from the FE (Java) as well.

      Perhaps we can implement this by having something like a MetricsGroup in Java which is accessed (serialized over JNI) by the Metrics code in the backend and merged into its metrics groups hierarchy for output.
