+=head1 NAME
+
+glassfish_counters_ - Wildcard-plugin to monitor counters in GlassFish
+
+=head1 CONFIGURATION
+
+This plugin does need the full path to the asadmin script:
+  [glassfish_counters_*]
+        env.ASADMIN /usr/local/glassfish/bin/asadmin
+
+This is a wildcard plugin. To monitor an subtree, link
+glassfish_counters_<subtree> to this file. E.g.
+
+  ln -s /usr/share/munin/plugins/glassfish_counters_ \
+        /etc/munin/plugins/glassfish_counters_server.web.request
+
+...will monitor server.web.request.*
+
+To ignore certain counters, just add more "IGNORE" lines on top of
+the awk script. (XXX: Fixme for env.)
