Hi Joshua, Keepalived doesn't communicate with haproxy. It keeps track of processes, interfaces, etc.
Generally you use vrrp_script option in keepalived configuration to keep track of processes (are they running? In your case haproxy) and if the process is not running, reduce prio by X which causes a failover. Read about vrrp_script in keepalived configuration. That's what you want to use. .pelle On Tue, Apr 16, 2013 at 11:07 AM, Joshua Chee <chee...@gmail.com> wrote: > In that case what is haproxy for?
