hongbin ma updated KYLIN-2776:
------------------------------
Description:
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
