Pre-tunnel latency vs Post-tunnel latency GP Logs

JasonMcNulty — Thu, 29 Oct 2020 20:07:14 GMT

Hello,

I am looking to understand a new feature of Prisma Access and the GlobalProtect client, which is the reporting of latency. I have read a few articles provide what the feature Is, but I would like to know the difference between pre-tunnel latency and post-tunnel latency.

For instance, I see the following in the logs:

Pre-tunnel latency: 74ms, Post-tunnel latency: -1ms

From my assumption, I think the 74ms is latency from the computer to the gateway or portal. What exactly is Post-tunnel latency? Is it latency between the portal and gateway? How can the latency be negative?

Hello, I know this old but did you manage to find information about your question?
I can't find anywhere on the Palo Alto docs what the difference between the Pre and Post tunnel latency is. Also what -1ms means

Thanks
