The most traffic Plugins ( for example check_snmp_int.pl ) use temporary files to store the previous values. > Please let me know your experiences of which fits into which category, of > if I've mischaracterized any of the above. I think graphing should be done by addons and not by the plugins. The check execution time must be as short as possible.
