How to extract Requests/Seconds (Throughput) of a performance test using Locust?

Question

I am running Locust performance Test against an API and I need to plot a Requests/Second vs Response time plot. I can see the req/s as a parameter in the results of the tests. Is there a Library/Class from where I can directly access this parameter ?

Answer 1

Have you looked at using the master report / slave report event hook (depending on where you want to log it from?

You havent said how you want to plot it, but we use something similar to shunt the metrics into a database to report on.

Answer 2

I think you can use the _requests.csv and _distribution.csv files that get generated if you pass in the --csv flag. These contain the requests/s column as well as the response times for different percentiles and also min, max, medain and avg. https://docs.locust.io/en/stable/retrieving-stats.html
