Hi,

When I go to Plesk --> Process list, the message below is shown.



An error has occurred while receiving disk operations usage. Stdout: Stderr: Traceback (most recent call last): File "/usr/sbin/iotop", line 10, in from iotop.ui import main File "/usr/lib/python3/dist-packages/iotop/ui.py", line 46, in from iotop.data import find_uids, TaskStatsNetlink, ProcessList, Stats File "/usr/lib/python3/dist-packages/iotop/data.py", line 51, in vmstat_f = VmStat() File "/usr/lib/python3/dist-packages/iotop/vmstat.py", line 23, in __init__ self.vmstat = self.read() File "/usr/lib/python3/dist-packages/iotop/vmstat.py", line 40, in read return pgpgin, pgpgout UnboundLocalError: local variable 'pgpgin' referenced before assignment Exit code: 1

Question: what is it and how to fix?

Thanks in advance

It could be a bug, but it could also be linked to the Python version used on the system. Did you update//modify Python after installing Plesk?

Hello Peter,

No, I did not update Python. Any Guidance on that?
