+# You MUST set the list of Xymon servers that this
+# client reports to.
+# It is good to use IP-adresses here instead of DNS
+# names - DNS might not work if there's a problem.
+# (Internally this will be translated to XYMSRV and XYMSERVERS
+# variables in /var/run/xymon/bbdisp-include.cfg)
+#
+# E.g. (a single Xymon server)
+#   XYMONSERVERS="192.168.1.1"
+# or (multiple servers)
+#   XYMONSERVERS="10.0.0.1 192.168.1.1"
+
+XYMONSERVERS="<% @list_server.each do |val| -%><%= val -%> <% end -%>"

+# Hostname used by the client for its reports.
+# Must match the name for this host in the Xymon servers'
+# hosts.cfg file.
