Load Balancing nsx how Enable Analitic based on source IP

[ivanunnio]

Hello guys,
Would someone know tell me how I can enable analytics on the source IP of the balancer on the Edge?
Thank you

In your application profile, there's a checkbox you can select to have the ESG insert an X-Forwarded-For HTTP header which references the source IP on the load balanced traffic.

Hi

This is  ?

Yes, checking that box will cause the LB to append an X-Forwarded-For HTTP header with the original source IP.

But th source ip i must change this ?

No, inserting the X-Forwarded-For header doesn't actually manipulate the IP address in the IP header so has no effect on persistence, it just adds the HTTP header at layer 7 that references the original source IP (especially useful incases like a one-armed deployment model where the LB is performing source NAT as it allows the terminating server in the pool to still have a way to tell what the originating IP was for analytics purposes).
