Jenkins: python script to evaluate performance of API requests: How to display in a chart/plot inside Jenkins UI

Question

I want to include functional and performance tests in our jenkins CI. For that purpose I wrote a script in python, the script is creating a XML report. Here is a part of the report:

<?xml version="1.0" ?>
<testsuite errors="0" failures="0" name="TestWaziGateDevices-20220330160133" tests="1" time="1.157">
    <testcase classname="TestDevices" name="test_post_get_delete_devices" time="1.157"/>
    <system-out>
<![CDATA[Created device with following ID: "624462bd1b002f0001c887f8"

Check for created device: http://192.168.188.29//devices/{"actuators":[],"created":"2022-03-30T14:01:33.554Z","id":"624462bd1b002f0001c887f8","meta":{},"modified":"2022-03-30T14:01:33.554Z","name":"test","sensors":[]}

Device was deleted if return empty string: 
If device was deleted it should show, that it was not found: device or sensor/actuator not found

....
Sensor   : Result of posted value: 9 Result of gotten value: 9
Actuator : Result of posted value: 9 Result of gotten value: 9
test_sensor_and_actuator_value: Time in total: 0.7713639736175537sek     Time for post one sensor value, check, post one actuator value and check: 0.07713639736175537sek
]]> </system-out>
    <system-err>
<![CDATA[]]>    </system-err>
</testsuite>

I recognized that it is hard to display the results of it in a chart in jenkins. I want to display the time the tests took and compare the builds. So on the x-axis there are the builds and y shows the time taken to finish the tests.

I tried to plot those values with the jenkins plot-plugin, but for that I have to also create a history xml or csv file where I read the values from the past builds.

Now I am investigating some plugins for Jenkins to display the chart: Blazemeter, Performance, JMeter. But those seem to have it limitations, because my URLs for the requests are not static, I got a token and device ID that changes, token needs to get renewed during tests.... That makes it very hard for me to fall back on some UI tools. I also wrote the script and it works, so I want to reuse it.

Is that a good approach to solve it?

Thanks for your time.
