LBActive Files

LBActive is an dynamic and active load balancer health check system written in
Python. Currently it supports only Nginx.

LBActive dynamically adjusts the weight of a weighted round robin or ip hash Nginx
load balancer by retrieving the current load on each backend server.

The next release (if there is one) will move to a more modular approach to enable
support for other load balancers that do not have dynamic and/or active checks and
other types of backend checks if needed.

LBActive is released under the GNU General Public License version 3.0 (GPLv3).
