Hi everyone,

Below,  we have security plocy with log option:

set security policies from-zone ZO to-zone ZOP policy T1 match source-address any
set security policies from-zone ZO to-zone ZOP policy T1 match destination-address any
set security policies from-zone ZOto-zone ZOP  policy T1 match application any
set security policies from-zone ZO to-zone ZOP policy T1 then permit

 

 

 But when i tried to see the logs generated by Policy I see a lot of files, which file contain the logs generated by policy?

Hi,

 

You may not be logging the message to a file yet. I suggest that you create a specific file for all the flow logs, see this kb here.

you need session-init /session-close option enabled on your policy to get policy logs.

 

set security policies from-zone ZO to-zone ZOP policy T1 then log session-init

set security policies from-zone ZO to-zone ZOP policy T1 then log session-close

 

then, if you are using high end devices, you need to set log-mode to event, by default its stream. If you are on branch devices you can ignore this as branch devices by defaylt use event mode

In a nutshell

#set security log mode event
#set system syslog file traffic.log user info
#set system syslog file traffic.log match "RT_FLOW_SESSION"
#set security policies ... then log session-close
>show log traffic.log

 

It's handy to trimm timestamps sometimes to have a more clear view

>show log traffic.log | trim 27

 

To monitor logs in real time

>monitor start traffic.log
>monitor stop
