How to count sessions at Palo Alto.

[awawa100]

Hello all.

I would like to know how to count sessions at Palo Alto.
I do not understand that the number of sessions is different between the two devices.
The two devices are Palo Alto and BIG-IP.
It is counted as 140 thousand sessions at Palo Alto and 30 thousand sessions at BIG-IP.
Thank you.

Hi @awawa100,

In short : On a Palo Alto Networks firewall, a session is defined by two uni-directional flows each uniquely identified by a 6-tuple key: source-address, destination-address, source-port, destination-port, protocol, and security-zone.

Find much more information about sessions on Palo Alto Firewall here :

Thankyou Kiwi.

In other words, when displaying a homepage containing one three images, will it be 1 in the page, 3 in the image, 8 sessions with this going and returning?
