+
+#REQUIRE_VERSION=1.8
+
+# This script test health-checks for four backends with one server by backend.
+# A syslog server is attached to each backend to check the syslog messages
+# in the righ order.
+
+# First, we check a health-check has passed for all the servers thanks to the syslog
+# messages. Then each server is disabled. The health-check status are checked.
+# Then each server is re-enabled. Finally health-check status
+# verifications for each server terminate the execution of this script.
+
+# Note that the CLI is synchronized with the syslog servers so that
+# to be sure to receive the passed health-checks status messages before
+# disabling the servers. Same thing, when we check that the servers are down
+# before enabling the servers.
+
+# Cyclic barrier to synchonize the CLI with the syslog servers
+barrier b1 sock 5 -cyclic
+
+# These servers are there only for the health-check test.
