The Sorter decides which +graphs are considerd interesting. + +Every sorter must inherit from the base class and provide it's own +methods for the 'business' logic. + +In order to maintain a decent performance the sorters activity is split into +two parts. + +The first part is active while the smokeping daemon gathers its data. +Whenever data is received, the sorter is called to calculate a 'value' for +the present data. On every 'query round' this information is stored in the +sorter store directory. Each smokeping process stores it's own information. +Since smokeping can run in multiple instances at the same time, the data may +be split over several files + +The second part of the sorter is called from smokeping.cgi. It loads all the +information from the sorter store and integrates it into a single 'tree'. It +then calls each sorter with the pre-calculated data to get it sorted and to +and to select the interesting information. + +=head1 DESCRIPTION + +Every sorter must provide the following methods: + +=cut + +use vars qw($VERSION); +use Carp; + +$VERSION = 1.0; + +use strict; + +=head2 new + +The new method expects hash elements as an argument +eg new({x=>'\d+',y=>'\d+'},x=>1,y=>2).
