 The actual configuration files for the web interface are generated in the template referenced by {{{LEMON_SERVER_WEB_CONFIG}}}. The default template is {{{monitoring/lemon/server/web}}}, which uses the NODES_PROPS list to build cluster definitions.

+=== Superclusters ===
+It is often useful to define "superclusters" that aggregate together existing node types. For example, a {{{GATEWAY}}} supercluster might aggregate all the {{{CE}}} and {{{SE}}} nodes at a site. The default web configuration template supports this as follows:
+
+{{{
+variable LEMON_SUPERCLUSTERS= nlist("GATEWAY",list("CE","SE"));
+}}}
