+# Configuration variables
+#   vservers - specify the vservers to include in the graph (default: all)
+#   limits - if true, turn on limit graphing (default: false)
+#
+# NOTE: If no configuration variables are set, the defaults will be used
+
+# Example /etc/munin/plugin-conf.d/munin-node 
+#
+# The first group monitors the vservers named "vserver1 vserver2
+# vserver3 vserver4" and looks to see if the resource limit has been
+# breached, if so it sends a message to nagios via send_nsca, and
+# sends an email to notify that this has happened.
+#
+# The second monitors the vservers "vserver5 vserver6 vserver7" and 
+# has no limit notifications turned on.
+#
+# The third monitors all vservers on the system, in one graph, and it has
+# no limit notifications defined.
+#
+# You can use any combination of these to fit your needs.
