InternalCacheMetricGroup

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".

参数:

parentMetricGroup - parent metric group of the subgroup

subGroupName - name of the subgroup
