hi, Ron. Indeed, I have rewrote the implementation of org.apache.hadoop.hbase.regionserver.metrics.RegionServerMetrics org.apache.hadoop.hbase.regionserver.metrics.RegionServerDynamicMetrics There are major changes as below: 1) change the context name for hbase to separate name for each other; like hadoop-metrics.properties: hbase-rsdm respresents DynamicMetrics and hbase-rs represents RegionServerMetrics.
2) add a filterMapper in Metrics, when it updates to ganglia or other metrics collector. so in our implementation, it will fetch the filter from hadoop-metrics.properties, and emit metrics as to settings. 3) In order to support dynamic add/remove filter in hadoop-metrics.properties, we alternatively add a rpc to restart metrics system in RegionServer without restarting rs.
