Palo Alto Traffic

Palo Alto PAN-OS Traffic logs — network session lifecycle with start/end/drop/deny subtypes, zone-aware flow profiles (trust, untrust, DMZ), source NAT translation, 30 App-ID applications, and byte/packet counters with lognormal distributions.

Quick Start

uv tool install eventum-generator
git clone https://github.com/eventum-generator/content-packs.git
cd content-packs
eventum generate \
  --path generators/network-paloalto-traffic/generator.yml \
  --id panw-traffic \
  --live-mode true

Event Types

Event ID	Description	Frequency	Category
end	Session ended — normal traffic termination	~72%	network
start	Session started	~14%	network
drop	Dropped before App-ID identification	~7%	network
deny	Denied after App-ID identification	~7%	network

Realism Features

4 zone flow profiles — outbound (trust→untrust 70%), inbound DMZ (15%), internal (10%), DMZ-to-internal (5%)
30 PAN-OS App-IDs with weighted selection (ssl, web-browsing, dns, ms-office365, ssh, etc.)
Lognormal byte/packet distributions — realistic right-skewed traffic volumes
Protocol-aware session end reasons — TCP uses tcp-fin/aged-out/tcp-rst; UDP/ICMP always aged-out
Source NAT translation only on outbound (trust→untrust) flows
Zone-matched security rules — allow rules for permitted traffic, deny rules for blocked traffic
