firewall log prefix not works

Hi. I use Proxmox 4.3-1 version. early I created iptables firewall and used it on lots of servers. There are some rules and the bottom lines are like that :

Code:

-A INPUT -j LOG_DROP
-A LOG_DROP -j LOG --log-prefix --DROP--:
-A LOG_DROP -j DROP

It's very easy. I use it on LVM that is on proxmox, but the problem is with containers. The firewall works great but there are no logs. I've googled ulogd and installed but there are errors :

Code:

Fri Feb 23 10:23:42 2018 <7> ulogd.c:813 error starting `log1'
Fri Feb 23 10:23:42 2018 <7> ulogd.c:1438 Could not nice process: Operation not permitted

My problem is that I want to create logs with iptables and I can't. for me It doesn't matter how I will do that.

So what can I check or how I can do that all?
