PaloAlto PanOS 10 - Logs not normalized

The only troubleshooting that can be done is for the non-compiled normalisers, as you can check the log messages against the patterns for those. But the compiled normalisers are as the name implies “compiled”, so their signatures are not visible outside of our source code.

I have just checked the Support tickets, and there does seem to be something going on with the Palo Alto logs in version 10.1, apparently the field count doesn’t match what we are expecting for THREAT and TRAFFIC logs. I suspect that Palo Alto threw in a few additional fields without telling anyone :)

I can see in the tickets that we have built some new normaliser versions over the last week or two, so it’s probably best to open a ticket and point out that you have problems with PanOS 10 - Support can decide what new package to share with you, rather than me picking one randomly from the Support ticket I see.

Thanks for your answer Nils. A i said, i took a quick look at the logs and couldn’t see any difference, but there might be some new fields i didn’t caught.

I will open a support ticket and will mark this querstion as solved.

Apparently, something also changed with how the fields are quoted, but only for some Palo Alto modules. So I am not entirely sure what the exact issue is, but no matter what I don’t think it’s anything that could be fixed through configuration...

You can try to confirm that Palo are sending logs for logpoint and se if it’s only normalization or lack of logs.

Do a search with : device_name=”your device” -norm_id=*

That will show you logs not getting normalized and you could easily se and identify the logs from Palo.

Are there no logs, then next step are Cli and tcpdump, se if there are arriving data from Paloalto.

Hi Kai,

already did this. Logs are indeed coming into the LP, they are shown in to repo. They are just” not normalized. Also did a tcpdump just to make sure new logs are coming in :-)

BTW: Does LogPoint have a URL with a listing of known bugs in the current release ? I couldn’t find any. As far as i understand Nils, there are known issues with the normalization of PanOS 10.1. Would have saved us some time if we would have known that before upgrading the FW, maybe we would have delayed the upgrade.

ok didn't get that, sounds like at job for the KB team, getting data normalized again, nice to know, so we will not upgrade right now, thanks ;)

Regards Kai

Hello,

My name is John Coughlan. I am a member of the regional support team here at LogPoint.

This should be the PAK file that you will need to install on your appliance that will normalize the incoming Palo Alto Logs.

Thank You

Depending on the logging configuration and Palo Alto OS version, the CSV normaliser might still struggle to normalise all fields correctly - for example, I have seen just the URL field go unnormalised. There appears to be a problem in the Palo Alto documentation as to which fields we should expect, and the fields seem to contradict each other in different versions. The fallback option is to switch the log format to CEF, as per this document https://docs.paloaltonetworks.com/content/dam/techdocs/en_US/pdf/cef/pan-os-10-0-cef-configuration-guide.pdf

The document contains examples of the custom CEF logging format to configure/create, but can be difficult to copy/paste as a single line from the PDF. The below is the list of fields that our CEF normaliser was built for, for each log type. You should be able to copy and paste each section from here as a custom log format for the respective log in Palo Alto. Also make sure to reconfigure the parser for the device in LogPoint to MultilineSyslog
