-------------------------------------
Summary: To improving Kylin logging abilities
Key: KYLIN-5560
URL: https://issues.apache.org/jira/browse/KYLIN-5560
Project: Kylin
Issue Type: Improvement
Components: Integration
Affects Versions: 5.0-alpha
Reporter: Guangyuan Feng
Fix For: 5.0-alpha
Currently most of the works, such as querying, are relying on the REST API, but
Kylin lacks the measure to trace the whole life of a request, including
accessing, handling, etc. Users have to pay much more time to find out the
relations between the request and the corresponding procedures.
In practice, we had add a new attribute `traceId` into each http request
{*}HttpServletRequest{*}, and into *org.apache.kylin.rest.interceptor.KEFilter*
utilizing log4j MDC(Mapped Diagnostic Context) tech to help us to improve the
situation.
So we hope our works could have the worth to improve Kylin.
