HAProxy is an amazing proxy, it has support for many different algorithms for load balancing, it can handle HTTP, TCP, WebSocket connects, does SSL termination and much much more. But managing these proxies can be a bit of a pain. That's where haproxy comes in, it provides a access to the stat socket of HAProxy which allows you to enable, disable servers and front-ends, read out stats and much more. In addition to that it's also capable of hot reloading configuration changes and starting, stopping your HAProxy, even when it's running as a daemon. In order to make your HAProxy installation work with this module you need to expose the stats socket interface of HAProxy. If you don't have this specified in your configuration please add the following to the global section of your configuration.
