Hi All, I am in the process of migrating from ultramonkey (lvs & heartbeat) to haproxy 1.5.4 for our environment. I have been really impressed with haproxy so far particularly the ssl offload feature and the Layer 7 flexibility for our jboss apps.
One of the VIPS that I have moved to haproxy is our exchange 2013 environment which is running in tcp mode (expecting approx 1500 concurrent connections on this VIP). I don't have any application/user issues yet but I wanted to get a handle on the haproxy stats page and particularly the 'resp errors' on the backend servers. The total 'resp error' count for the backend is 249 but when I hover over the cell it tells me 'connection resets during transfer 314 client, 597 server'. This doesn't seem to add up? I assume this counter is accumulative? As a rule of thumb what sort of percentage would I be concerned with when looking at this figure?
