help with graph interpretation of "Latency over time"

[Mateus Guilherme <ma...@gmail.com>]

Hi

I have a question about the latency graph over time generated with the
"Graphs Generator" plugin. The plugin "View Result Tree" generated the
report "reports.csv" (or "report.xlsx" already separated by columns). It is
possible to see the 100 HTTP requests generated by the 100 threads that I
configured in the "Thread Group". In this report it is possible to observe
that there are requests with latency values of 331ms, 334ms, 339ms 341ms,
342ms, but in the chart "LatenciesOverTime.png" these values do not appear.

To generate the graph I'm using the value of 1ms in the field "Granulation
time for samples" of the plugin "Graphs Generator". If we analyze the file
"LatenciesOverTime.csv" it is possible to see that the highest latency
value it contains is 272ms. Why don't the higher latencies, which appear in
the reports.csv file (334ms, 339ms, 341ms, 342ms... ) appear in the graph?

thanks

Hello Mateus,

Your question may be better-answered in the JMeter Plugins group over at
Google Groups.
https://groups.google.com/g/jmeter-plugins

Maybe you have too many samples in too-tiny a window that is causing the
plugin to miss a few points? I can't say for sure. I don't suppose using
the smallest granularity possible would result in *all* points being
included in the graph.

I would, however, trust JMeter results file (csv/jtl) over the graph.
And--given that you have a very small number of samples--you do have the
option of plotting those using Excel.
