Here is a group of UnDP pollers and transforms I created to monitor and display the sessions on a Palo Alto Networks firewall.
The pollers and transforms are:
- Total Active Sessions
- Active TCP Sessions
- Active UDP Sessions
- Active ICMP Sessions
- SSL Proxy Sessions
- SSL Proxy Utilization
We use the pollers for displaying charts and transforms for gauges. I use transforms to make the gauges more readable, you can display the pollers with a gauge and without using transforms. The gauge threshold values are based on the published specs for a PA-3050.
