public class InternalCacheMetricGroup
extends ProxyMetricGroup<org.apache.flink.metrics.MetricGroup>
implements org.apache.flink.metrics.groups.CacheMetricGroup
    A CacheMetricGroup which register all cache related metrics under a subgroup of the parent metric group.

        public InternalCacheMetricGroup​(org.apache.flink.metrics.MetricGroup parentMetricGroup,
                                String subGroupName)
        Creates a subgroup with the specified subgroup name under the parent group. Metrics will be registered under the new created subgroup.

        For example the hit counter will be registered as "root.cache.hitCount", with parentMetricGroup = root and subGroupName = "cache".

        Parameters:
        parentMetricGroup - parent metric group of the subgroup
        subGroupName - name of the subgroup
