+=item B<Scale> I<Value>
+
+The gauge-values returned by the SNMP-agent are multiplied by I<Value>. This
+is useful when values are transferred as a fixed point real number. For example,
+thermometers may transfer B<243> but actually mean B<24.3>, so you can specify
+a scale value of B<0.1> to correct this. The default value is, of course,
+B<1.0>.
+
+This value is not applied to counter-values.
+
+=item B<Shift> I<Value>
+
+I<Value> is added to gauge-values returned by the SNMP-agent after they have
+been multiplied by any B<Scale> value. If, for example, a thermometer returns
+degrees Kelvin you could specify a shift of B<273.15> here to store values in
+degrees Celsius. The default value is, of course, B<0.0>.
+
+This value is not applied to counter-values.
+
+=item B<Ignore> I<Value> [, I<Value> ...]
+
+The ignore values allows one to ignore Instances based on their name and the
+patterns specified by the various values you've entered. The match is a
+glob-type shell matching.
+
+=item B<InvertMatch> I<true|false(default)>
+
+The invertmatch value should be use in combination of the Ignore option.
+It changes the behaviour of the Ignore option, from a blacklist behaviour
+when InvertMatch is set to false, to a whitelist when specified to true.
