467391 - Find out what files in sumo tree have been accessed in last 3 months

Description

[Nelson Ko [:nkoth]]

For bug 442916, we would like to know what files in the sumo tree have been accessed in the last 3 months, and also what files have not been accessed in the last 3 months.

This should be done on one of the production servers.

Probably all the files have been accessed via svn update some time in the past, or some kind of backup, etc..., but these should not count. We want to know whether they are in fact used by sumo. 

So a command like "find . -atime -90" or "find . -atime +90" will not work. I think this info needs to be combined with "accessed by the apache user" to be correct.

Any other suggestions are welcome.

I don't think there's anything in the Linux OS that records this information.  The atime is the best you'll get.  Not to mention I think we have atime disabled on the netapp mounts anyway.  The closest we'll get on this is probably looking at the webserver logs, and that'll only tell you things that are directly accessed from the web.
