> 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 refactored QueryMetric with new metrics, notice the exposed JMX MBeans
> have changed a little bit.
> A new tool called perflog is also introduced. Perflog traces call duration
> time and current active calls by recording them to metric system.
> Some snapshots of the new JMX MBeans can be seen in attachments
