amazon web services - Behind AWS ELB : How to grab the Real IP from "netstat"?

Question

I'm using AWS Elastic Load Balancing (ELB) in front of 2 Linux Web Servers. But (based on my requirement) i need to know the Real IPs from the Web Servers' perspective, especially when i use netstat.

I need to know the number of incoming connections from each IPs (from NETSTAT), as in real time. So basically in Linux (without ELB in front), below netstat command perfectly works:

netstat -tn 2>/dev/null | grep :80

But now i can only see the internal IP(s) of the ELB; which is making the whole thing quite difficult.

What is the solution for this please? Thanks.

Answer 1

You could get the client source IP from ELB Access Logs and use EMR with Hive to count the number of times a client request came in from the same IP.
