What's a good tool for collecting statistics on filesystem usage? [closed]
You probably want something that will log file system events with inotify. Maybe something like logsend. Also see inotify-tools.
Wow. Novell has something a lot like this for their Open Enterprise Server on NSS volumes that gives most of that. Not frequency of access, that's proxied by last-access-date, but definitely the rest of it. It's a Java processes that crawls the volume tree to build what they call an Inventory. I'm pretty sure it isn't open sourced, but that report is rather nice to have.
