Zabbix trapper port

[quasi_modo]

How can I pass debug mode to level 4 on Zabbix ?
I've uncomment the line

# DebugLevel=3

and now this line is

DebugLevel=4

but I don't know if I correctly apply your advice.


Then I check iptables and I found nothing strange, but I'm not an as with iptables

Chain INPUT (policy ACCEPT)
target     prot opt source               destination

Chain FORWARD (policy ACCEPT)
target     prot opt source               destination

Chain OUTPUT (policy ACCEPT)
target     prot opt source               destination

yes, you changed it correctly. Make sure you have restarted zabbix_server, since it reads config file only on restart.
Log file will start to grow much faster, make sure you have enough space and proper file rotation so the interested part will not get overwritten too fast.
