Hi all,
I have an updated ntopng/pfring-zc installation and when I start ntopng the
following messages are produced:

Why the view of all queues does not work? How should i write this line?
When I delete from ntopng.conf, the
"view:zc:ens160@0,zc:ens160@1,zc:ens160@2,zc:ens160@3" line, the I get another
bunch of warnings:

The ntopng then, seems to be working but I would like to get rid of the errors.
What should I do to avoid the hugepages errors? I'm running ntop as root
(though I can see it drops privs).
My conf:
-G=/var/run/ntopng.pid
--data-dir=/mnt/data/ntopng
