Probably what the OP is looking for ;o) . However beware that if cache
policies are disabled then you might end up cleaning a lot of garbage

performance penalties might occur since graphs need to be generated
more often. Suggestion : *be careful* and choose values considering
server load , mean graph size, disk space, ...
