Hey, I have a dynamic backend with maxconn 80 with multiple servers. Many times I can see on the haproxy stats page that servers on this backend are reaching their maximum 80, but I don't see the number of requests currently in queue. The maximum number I ever see is 80. Why is that? Can I somehow see the number of requests in the queue?
Also, with a munin plugin that checks the HTTP page with ";csv", I see that sometimes the graphs shows 400+ req/sec for this backend, which is not possible since the maximum is 80... Last, what is the difference between "Sessions" and "Session rate" ? How can I tell when I need another dynamic backend server? Thanks! Bar.
