How to change syslog timestamp format

L1 Bithead

Hi,

We are using syslog forwarding to SIEM system from our PA. Logs were in this format:

 

1,2017/09/06 23:59:59,007100001147,TRAFFIC,end,0,2017/09/06 23:59:59,X.X.X.X,Y.Y.Y.Y,0.0.0.0,0.0.0.0,Firewall To NTP,test\paloalto,,dns,vsys1,Inside,Inside,ethernet1/1,ethernet1/1,Q-Radar,2017/09/06 23:59:59,79361,1,42407,53,0,0,0x4064,udp,allow,409,176,233,4,2017/09/06 23:59:29,0,any,0,6849234946,0x0,172.16.0.0-172.31.255.255,172.16.0.0-172.31.255.255,0,2,2,aged-out,0,0,0,0,,PA-VM,from-policy

 

But now the log timestamp was changed and looks like this: 

 

Sep 12 09:22:13 X.X.X.X 1 2017-09-12T09:22:14+04:00 X.X.X.X - - - -  1,2017/09/12 09:22:13,007100001147,TRAFFIC,start,0,2017/09/12 09:22:13,Y.Y.Y.Y,157.240.9.23,0.0.0.0,0.0.0.0,Internet Access For Mrktd,test\user1,,facebook-base,vsys1,Inside,Outside,ethernet1/1,ethernet1/3,Q-Radar,2017/09/12 09:22:13,3539,1,4378,443,0,0,0x4000,tcp,allow,763,697,66,4,2017/09/12 09:22:14,0,social-networking,0,6936146804,0x0,172.16.0.0-172.31.255.255,US,0,3,1,n/a,0,0,0,0,,PA-VM,from-policy

 

As you noticed  this entry was added  to logs : Sep 12 09:22:13 X.X.X.X 1 2017-09-12T09:22:14+04:00 X.X.X.X - - - -  

Maybe you know what was the reason of this?

It will be great if you help us to remove this entry from logs.

Hi @BankRespublika,

 

I can't say why the entry was added... I don't know the reason why it was added.

 

You can however customize the log entries.

Depending on your PAN-OS version you can find the CEF configuration guide here :

 

https://www.paloaltonetworks.com/documentation/misc/cef.html

 

For example Traffic Log on PAN-OS 8.0 :

 

 
These custom formats include all the fields, in a similar order, that the default format of the syslogs display.
