This gem aims to provide an interface to query HAProxy for statistics, and eventually management through the sockets API.
HAProxy is the Reliable, High Performance TCP/HTTP Load Balancer.
- I use HAProxy at my work.
- I wanted to know how to create gems.
- I wanted to contribute with OSS.
- Why not?
- All of the above.
