RE: [Grinder-use] Logfile Data (Technical Meaning)

[Fitzgerald, C. <Cal...@Th...>]

 
Your formula needs to be:

formular: Total Response Length / ( Total Test Time - Total Time to first
Byte )

This would give you an average for "Response bytes per second" for the whole
test run.

The time to first byte metric gives you  a measurement of when the
serverside application has finished process your request and starts to send
you its response.

The metrics for Time to Resolve host, Time to establish connection and Time
to first byte are all measured from the start of the "TestStep", they are
not incremental.

Subject: RE: [Grinder-use] Logfile Data (Technical Meaning)

Does this calculation make sense of "Response bytes per second", when we run
this test case as a single virtual user (only one user is running and
measuering)

Eg this log is beeing printed:

"TestSteps"   TestStep time  response length   Time to resolve host   Time
to establish connection	  Time to first byte    TestDesc
1              621	   	   2450	           100
421	               611              "GET glbl_ie6.css"
2              80	           1029	           0
0	                       80               "GET portal_body_bg_img.gif"
3              101	           329	           0
0	                       101              "GET basic.js"

Total          802                 3808            100
421 


formular: Total Response Length / ( Total Test Time - Total Time to resolve
host - Total Time to establish connection )

= (2450 + 1029 + 329) / ((621+80+101) - (100 + 0 + 0) - (421 - 0 -0 )) =
3808 / 281 = 13,81 Response Bytes per second

Would it be possible to measure accurately the throughput with the
httpClient Plugin?

Currently (only for one running VU) I see one recorded script as one test.
And one line as a test step, or as a nested Tests for later analysis.
