sum of all sample request throughput is not matching with total tps

sum of all sample request throughput is not matching with total throughput:

Example:-
sample 1 throughput - 9528.37
sample 2 throughput  - 2219.28
sample 3 throughput - 1900.87
sample 4 throughput - 3443.52

---------------------------------
Sum of all samples -  9528.37+2219.28+1900.87+3443.52 = 17092.04  but in HTML
report total throughput is showing as 7603.34


can you plz help how this calculation happens

output summary:-
summary = 10500000 in 00:23:01 = 7601.6/s Avg:    54 Min:     3 Max:  2479 Err:
  441 (0.00%)

Can you open your test plan and run :

Tools > Generate Schematic Overview

and attach result here.

Thanks

TPS per sample occurrence duration vs TPS per test duration

My guess is that jmeter TPS is calculated for each sampler bases with it's
start/end time, which will give different results when you do the same for
whole group. Please see the the attachment.

As you can see for "reset-wiremock" example (single request sent), JMeter
calculated throughput for time between the first sample going out timestamp and
last sample coming in timestamp, which results with 3.2 TPS for single request
over 300 seconds (1 sample and duration 0.312s -> 3.2 TPS). 

It's a matter of question, how you would like to calculate TPS for each sampler
- per sampler occurrence, or per whole test
