kpm_mon_xapp.py not giving expected metrics output

[rajyay]

Hi Community, I followed the tutorial in the link https://docs.srsran.com/projects/project/en/latest/tutorials/source/near-rt-ric/source/index.html . I used open5gs, srsRAN_Project, ORAN SC RIC, srsUE, and kpm_mon_xapp.py as mentioned in the tutorial. I have used single Virtualbox machine for all of these components. uplinkg Iperf3 traffic is generated and all things running fine as stated in tutorial but i am not getting the expected metrics from kpm_mon_xapp. The output i obtained in xapp side is as follows:
vboxuser@srsran:~/oran-sc-ric$ sudo docker compose exec python_xapp_runner ./kpm_mon_xapp.py --metrics=DRB.UEThpDl,DRB.UEThpUl --kpm_report_style=5
[sudo] password for vboxuser:

And, in ORAN SC RIC side, i am getting as follows:
