> 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 by recording them to metric system.
> Attachment is the difference between the two metric system .
