Statistical Aggregate report Intreprtation - testing

Question

It might be a trivial question but please share your experience with me.
I am using Jmeter in GUI mode and added an add on "Statistical Aggregate report" Listener.
But I am unable to interpret the Graph I am getting from this Listener.How could it be useful for the performance testing. What sort of information I am getting ?
Thanks in advance

Answer 1

Suppose you've better study theoretical info about performance/load-testing artifacts and metrics first and than decide which listeners/graphs are necessary for your testing.
You could also look onto jmeter-plugins graphs - they are in many cases more informative/descriptive than jmeter's ones.
UPDATED:
Statistical Aggregate Report listener is kind of combination of Graph Results and Aggregate Report listeners into one chart where you get statistic for 2 important performance characteristics measurements - throughput (hits/sec) + Avg. Response Time (msec) - across the test execution time.
See both listeners descriptions for details about characteristics they are measuring:
The throughput number represents the actual number of requests/minute
the server handled. This calculation includes any delays you added to
your test and JMeter's own internal processing time. The advantage of
doing the calculation like this is that this number represents
something real - your server in fact handled that many requests per
minute, and you can increase the number of threads and/or decrease the
delays to discover your server's maximum throughput.
Roughly:
response time = "time to last byte"
latency = "time to first byte"
throughput = number of requests / time unit
For programming realization I'd better look into source code available.

Answer 2

I found an issue will be occurred with the third party Listener plugin "Statistical Aggregate Report" while we clear the Test Results in JMeter
