[pm-h] [SPAM] [PBML] complex data structure help

[Paul Archer]

I'm writing a log analyzer (a la Webalyzer) to analyze Solaris' nfslog 
files. They're in the same format as wu-ftpd xferlog files. I'd use an 
existing solution, but I can't find anything that keeps track of reads vs 
writes, which is critical for us.
Anyway, I need to be able to sort by filesystem, client machine, user, time 
(with a one-hour base period) read, write, or total usage.
Can anyone suggest a data structure (or pointers to same) that will allow me 
to pull data out in an arbitrary fashion (ie users on X day sorted by data 
written)?
Once I have the structure, I can deal with doing the reports, but I want to 
make sure I don't shoot myself in the foot with the structure.

I was thinking of a hash of hashes, where the keys are filesystems pointing 
to hashes where the keys are client machines, etc, etc. But it seems that 
approach would be inefficent for lookups based on times or users (for 
example).

Any help would be greatly appreciated.

Paul
