### Feedback

I want to track the test progress of jmeter and display it in real time as a percentage. Is there any jmeter API plz?
This is my testplan running in conatainner:
This is the display effect I expected:

docker image : alpine/jmeter:5.6.3

jmeter -version:5.6.3
java -version:
openjdk version "1.8.0_402"
OpenJDK Runtime Environment (IcedTea 3.30.0) (Alpine 8.402.06-r0)
OpenJDK 64-Bit Server VM (build 25.402-b06, mixed mode)
os:
NAME="Alpine Linux"
ID=alpine
VERSION_ID=3.20.3
PRETTY_NAME="Alpine Linux v3.20"
HOME_URL="https://alpinelinux.org/"
BUG_REPORT_URL="https://gitlab.alpinelinux.org/alpine/aports/-/issues"

Read the realtime-results documentation at https://jmeter.apache.org/usermanual/realtime-results.html and compare it with the requested real-time percentage display. Investigate whether JMeter 5.6.3 exposes an API for test progress in the reported Docker environment; done would require a clearly documented supported approach or a defined feature proposal.
