Log Exporter not Showing all Fields

Jump to solution

I have log exporter set up to export logs via syslog in CEF format. I'm noticing that a lot of the IPS logs are often missing fields, mainly the destination IP and ports. I've verified that these fields are listed in the conf files and not being blocked from being exported. I've pasted a couple of examples below. This for R80.20, and wondering if anyone else has seen this, or if this is normal and if so, any ideas as to why?

Examples:

Please try to change the log exporter configuration to use "semi-unified" reading mode (describe in SK122323).
Let me know if it helped.

Have you confirmed the log entries these correspond to in SmartView have the information?

Hi Mike,

We encounter same problem on the same environment.

Were you able to figure out the reason?

Thanks in advance

We are also experiencing a similar issue in our environment. I have a ticket opened with TAC and have also notified our SE, but wanted to see if any insight could be shared here. He did switch to semi-unified read mode. and that improved things, but we are still missing some of the data on a subset of exported logs.

We are on R80.30 with JHF Take 111 and are exporting to LogRhythm. FWIW, ran some pcaps and the missing data is evident there. Any guidance appreciated.

Hi,

You mentioned that you cannot see all field in the log entities after export operation.

Can you please tell me what made you think these fields should be there?

What you actually can do is to find one log entity that may be "broken" in LogRhythm and look for the same log (from the same time) in your SmartConsole.

All fields should behave the same - meaning that every field exist in SmartConsole, should also be seen in LogRhythm.

If you need an additional help with it, please contact me at shayhi@checkpoint.com and I will try my best to help.

Hi Shay, thanks for the response. It's not the fields that are missing, it's the data. For example - Destination IP. I have confirmed we see it in SmartLog, however, with a PCAP I have confirmed it is not being exported in some cases. I will reach out to you directly.
