JMeter to ignore warmup period

Contrary to How to exclude warmup time from JMeter summary?, as I don't want to spin up 20 threads all at once. Instead,

I want to ignore a certain warmup period (or a certain iterations), to exclude the initial visit outliers, illustrated clearly in the following chart:

enter image description here

Very close to JMeter structure warmup, however, not specifically to "a child of the request you want to ignore". I.e., I want to apply to all samplers/requests for all threads.

So instead of "Add JSR223 PostProcessor as a child of the request you want to ignore", I need to add a generic JSR223 PostProcessor at thread group level to control all samplers/requests. Is that possile? If so, how should I do? I remember that the JSR223 code should mention parent() or something like that.

Solution

  • After you get results you can exe ute Filter Results Tool to remove warm up using start-offset parameter with seconds

    If you want to remove the ramp-up phase, you could use offset filters.

    FilterResults.sh --output-file filteredout.xml --input-file inputfile.csv --start-offset 2
