RHEL7 Rich Rule firewalld

Hi guys,

thanks for always helping.

I am a little confused with rich rules. Here is an example

' firewall-cmd --add-rich-rule 'rule family=ipv4 source address=192.168.3.0/24 service name=http log prefix=http allow rule' level=info accpet --permanent'

Question : what does options do " log prefix=http allow rule' level=info accept "

Thank you
