PPP logs analysis.. recommended options?

["hogan" <hogan@netspace.net.au>]

I'd like to start analysing my PPP connections..

How often they drop out, how many bytes they transfers in a session, how many
errors they encounter.

I'm sure someone's already made a package to analyse one's log files - what
are the recommended options?

Running (/proc/version):
Linux version 2.2.16 (root@dabox) (gcc version 2.95.2 20000313 (Debian
GNU/Linux)) #2 Fri Jun 16 23:15:28 EST 2000
Latest unstable from ftp.au.debian.org (well excluding the kernel obviously :)

Had a play with egrep/grep -E from CLI but I figure there's no point
reinventing a perfectly good wheel :)
