set maxconn server

Description

You can define a maxconn setting on each server line in a backend section of your configuration. This limits the number of concurrent connections that HAProxy Enterprise will relay to that server. When this limit is reached, connections queue up in the backend until a server slot becomes free.

backend webservers
   server s1 192.168.0.10:80 maxconn 30
   server s2 192.168.0.11:80 maxconn 30
   server s3 192.168.0.12:80 maxconn 30

Use the set maxconn server command to change this limit dynamically. A value of zero is allowed.

Examples

Below, we set the server s1 in the backend webservers to have a maxconn of 20:

$ echo "set maxconn server webservers/s1 20" | \
   sudo socat stdio unix-connect:/var/run/hapee-2.2/hapee-lb.sock
