With https://issues.apache.org/jira/browse/KYLIN-2721.We are plan to release a new metric framework. 
New metric is different hadoop metric  and based on dropwizard . which has the following advantage:
*     Well-defined metric model for frequently-needed metrics (ie JVM metrics)
*     Well-defined measurements for all metrics (ie max, mean, stddev, mean_rate, etc),
*     Built-in pluggable reporting frameworks like JMX, Console, Log, JSON 

We refactor QueryMetric with new metris. 
New metric  add perflog. Perflog  trace calls duration time  and current active calls record to metric system.
 Attachment is  the difference between the two metric system .
