From 8ede380f1d4d702bf29ea31e6f66dafd8518c759 Mon Sep 17 00:00:00 2001 From: Sam Yaple Date: Wed, 5 Aug 2015 11:10:53 +0000 Subject: Add check_script for haproxy in keepalived This patch checks that haproxy is alive and running. It does this by using socat to talk to the haproxy socket. That socket will only respond successfully when haproxy is active and functional.
