+=head1 NAME
+
+  fsstat_act_ - Munin wildcard plugin to monitor Solaris file system statistics
+
+  This plugin monitors full activity of file system like fsstat -f .
+  See man fsstat for more details.
+
+  Tested with Solaris 10 and 11. And should work with Solaris 10 11/06 or above.
+
+  Note:
+    In Solaris 11, fsstat command can get stats for each non-global zones in 
+    global zone. (see man fsstat)
+    In global zone, this plugin gets stats of only global zone.    
+    In non-global zones, this plugin reports stats of the non-global zones.
+
+=head1 CONFIGURATION
+
+  This plugin monitors statistics per file system type. Available file system
+  can be shown by fsstat command.
+
