I'm trying to find tools to help identify what I call 'file movers' -> files that are created/deleted at any given time that have certain sizes (i.e. > 1mb for example), and files that have growth (i.e. > 5% for example). Pre-identification of the files should not be required, although the directory in which files to watch would be fine.
Does nagios have something similar to this? My use-case actually isn't production, I would rather have a tool to identify these during development of applications -- however, if this actually can be done in production, that would be great as well!
