+Valid options are B<host>, B<plugin>, B<plugin_instance>, B<type> and
+B<type_instance>. Each option takes a regular expression as its argument. If at
+least one regular expression is supplied, only values where each appropriate
+part of the identifier satisfies the given regular expression are returned.
+
+Example:
+ -> | LISTVAL plugin_instance="^$"
+ <- | 5 Matching values
+ <- | 1300311250.802 myhost/load/load
+ <- | 1300311250.802 myhost/memory/memory-buffered
+ <- | 1300311250.802 myhost/memory/memory-cached
+ <- | 1300311250.804 myhost/memory/memory-free
+ <- | 1300311250.802 myhost/memory/memory-used
+
+Regular expressions follow the I<Extended Regular Expression> syntax (ERE)
+described in L<regex(7)> and will match case-sensitive. It is recommended to
+enclose the regular expression in double quotes. Please note that you will
+need to escape the backslash and double quote characters in this case. To
+request all values from hosts with the German top level domain ".de", for
+example, use:
+ LISTVAL host="\\.de$"
