It would be nice to have a feature that it saves configuration equipment (ex Switches) and pool this data (ex everyday) and have a history data what changes. Some sort of SVN type. You can see difference from new config from previous config (ex. Added Line, Changed lines and removed lines). Right now we use RANCID ( link: http://www.shrubbery.net/rancid/ ) for doing it, it would be nice if this feature integrated or built in into Netxms.
