+=item B<Timeout> I<Iterations>
+
+Consider a value list "missing" when no update has been read or received for
+I<Iterations> iterations. By default, I<collectd> considers a value list
+missing when no update has been received for twice the update interval. Since
+this setting uses iterations, the maximum allowed time without update depends
+on the I<Interval> information contained in each value list. This is used in
+the I<Threshold> configuration to dispatch notifications about missing values,
+see L<"THRESHOLD CONFIGURATION"> below.
