Updated haproxy-sessions-by-servers to look at the current sessions by individual servers. I believe this was the original intent of the script (it was broken by default when symlinking it in /etc/munin/plugins/ (/etc/munin/plugins/haproxy-sessions-by-servers). NOW SUPPORTS: - URL + Socket Stats - Dynamic list of individual backend member servers - tested / works with munin-node NUANCES: - may be annoying with an absurd number of backend member nodes (I have 10 on this particular haproxy instance)
