IOTOP on LXC

[SPQRInc]

Hello,

unfortunately I can not use iotop on proxmox-lxc-container and debian 8 template.

This is the output:

Traceback (most recent call last):
File "/usr/sbin/iotop", line 17, in <module>

File "/usr/lib/python2.7/dist-packages/iotop/ui.py", line 620, in main

m = GeNlMessage.recv(self.conn)

msg = conn.recv()
File "/usr/lib/python2.7/dist-packages/iotop/netlink.py", line 229, in recv
raise err
OSError: Netlink error: No such file or directory (2)

Does anybody know how to fix that?

Exactly the same issue here with Debian 8 and Proxmox 4.1

Any solutions?
All that Google reveals seems to be resolved via a kernel update...

You can use a specialized version from iotop for cgroups where you can define the lxc container you want to monitor:

./iotop.py -g /lxc/1234/ns
