HAProxy Enterprise Documentation 2.7r1
The HAProxy Runtime API is built into the load balancer as a way to view and change its behavior without needing to reload the process. The HAProxy Data Plane API invokes Runtime API methods for some features to avoid a reload.
Key points to remember when using the Runtime API include:
Change are made in running memory only and do not persist if HAProxy Enterprise is reloaded or restarted.
The API can be accessed over a UNIX socket or a TCP/IP address.
You can execute commands ad hoc or, when using the UNIX socket, start an interactive session.
