I have a proxy traffic server which is an extra hop on a network and is handling large quantity's of traffic.
I would like to calculate the cost in seconds of how long it takes for the proxy server to handle the incoming request, process them and forward it on.
I had been playing to write a python script to perform a tcpdump and some how time packets entering into the server until they had left.
I would probably have to perform tcpdump for a certain period of time and then analysis it to calculate times?
Is this a good way of achieving what I want or would there be a more elegant solution?</div
