Subject Apache Phoenix Tracing Dashboard-jira issue PHOENIX 1118
Date Wed, 22 Apr 2015 08:52:58 GMT
Hi All,

I'm a University Student applying for the GSOC Project [1] Dashboard for
tracing information in Phoenix. In Apache Phoenix, HTrace is used to
provide request level trace information.
Below are the trace information found in Phoenix Table.

   -       trace_id
   -       parent_id
   -       span_id
   -       description
   -       start_time
   -       end_time
   -       hostname
   -       tags.count
   -       annotations.count

HTrace library is integrated with HBase tracing utilities. And HTrace
latest release 3.2.0 will include many visualization improvements[2].

You can find the Mock Up UI [3] which gives advance search capabilities for
trace attributes and slider functionality[4] to view the trace for the
selected time period with zooming capabilities and parent trace info on

A web UI is the solution proposed and a dashboard will show the required

Can the Phoenix SYSTEM.TRACING_STATS table be made available in the htrace
web gui? Which will further cater for the needs of visualizing the trace
info as the Mock Up UIs suggest.

Pagination will be tackled in the visualization of the tracing.


Best Regards,
Ayola Jayamaha
