How can I log the flow on CSS

[yahshianhui]

I have a CSS which is distributing https requests to 2 web-servers. The host master for the web-servers see that the CPU utilization on 1 server is 50% higher than the other server. He is convinced that the load balancer is not performing the loadbalancing properly. Source sticky is configured on the load balancer.

Is there anyway to log the flows on CSS? Currently, we are able to see real time information by performing a "show flow". Is there any way to log this information to a log server or a disk? Please advise.

with sticky source-ip you definitely do not get equal loadbalancing.

Moreover, you can do a 'sho summary' to see the distribution of flows accross your servers.

No need to log all flows.

Sticky source-ip can give you bad loadbalancing result due to megaproxy. This is something well-known.

This is why a lot of people install ssl module to decrypt https traffic and use sticky based on cookies.
