HAProxy is an open-source load balancer that can load balance any TCP or HTTP service. For more information about HAProxy, see http://www.haproxy.org/.
The NetScaler Management and Analytics System (MAS) supports HAProxy version 1.4.24 or later. When you add a host on which you have provisioned the HAProxy instances to NetScaler MAS, NetScaler MAS discovers the HAProxy instances on the host and enables you to monitor them. It shows you the following types of information about the HAProxy configuration on the instances:
- Frontend – How requests should be forwarded to the back end.
- Backend – The set of servers that receive the forwarded requests.
- Servers – The servers among which HAProxy load balances the traffic.
For more information, see http://www.haproxy.org/download/1.7/doc/configuration.txt.
Also, NetScaler MAS provides an HAProxy App Dashboard on which you can monitor the frontends in real-time. For more information, see HAProxy App Dashboard.
