Hi ,

We like to know net-flow configure for Palo Alto firewall. We notice the NetFlow traffic to our NetFlow server are inconsistence.

What we need to find out are as below :

Will the Firewall cache the Netflow data?
How frequent is the Netflow data transferred and the interval timing the packet are send out?

Thank you

Also check out this video tutorial from solarwindsinc where they explain how to edit the default values from the Template Refresh Rate (to minimize data gaps) and Active Timeout (this controls how ofter active cache flows are exported):
