            Bug ID: 57222
           Summary: Aggregate Report and Summary Report should be merged
                    in one listener
           Product: JMeter
           Version: 2.12
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P2
         Component: Main
          Assignee: issues@jmeter.apache.org
          Reporter: p.mouawad@ubik-ingenierie.com

Comparing features and codes of the 2 listeners, I see the following:
- Code similarity is due to SummaryReport supposed to be "Simpler (lower
memory) version of Aggregate Report (StatVisualizer)". A comment says "Excludes
the Median and 90% columns, which are expensive in memory terms"
- The 2 report nearly the same thing except for Median and Percentile and also
Avg Bytes being in Summary Report


But looking at implementation, it seems the main argument "Excludes the Median
and 90% columns, which are expensive in memory terms" is not more valid as:
- I don't see in StatVisualizer(Aggregate Report) high memory consumption as
this class uses StatCalculator under the hood which does not accumulate values
for Percentile and Median computation but counts values rather than storing
them.
Not if it was not efficient enough we could use Commons Math
DescriptiveStatistics which uses an array of doubles (with a sliding window) as
per sebb previous note in one of our mail discussions.


So I propose to add to Aggregate Report Avg. Bytes and deprecate Summary
Report.

[Bug 57222] Aggregate Report and Summary Report should be merged in one listener

--- Comment #1 from Sebb <se...@apache.org> ---
At the time when the Summary Report was created, the Aggregate Report used a
different way of calculating the results, and was much more of a memory hog.

The Summary Report columns were decided based on the calculations that don't
need to store multiple samples. I think it is still useful, and I don't support
deprecation.

Even though Aggregate now uses much less memory, it still requires more memory
than the Summary.

In my opinion, what would be more useful would be to allow the Aggregate
columns to be specified. Label and count should always appear, but most - if
not all - the others should be optional. And the %ile values should be
specifiable, as per Bug 57217
