Hey,

I was looking for a simple solution to view past firewall logs on the firewall, but displaying them in plain view is pretty much unusable.
So I created a small application with a GUI to import the data locally and process it easily on your PC without having to set up a syslog/graphana solution.

I think this could be useful to others, so you can find it on GitHub.

ps: Retrieving label information via root is not very elegant, so if you have a better suggestion, I'm all ears.




Great, such a toll a searching a long time.

But Defender shows Trojan:Win32/Sabsik.FL.A!ml

Hi Steffen,

Thanks for your feedback. 
I submitted the file to various vendors so that it would be less likely to be detected as malware.
The program can still be launched directly from the sources with Python.

Great Tool. Thank you for sharing.
