No. Totaly unpractical and insane. Why? well, volume of logs will kill
your database really well. Secondly, your database will be constantly
updated (which is slow, or so I am told by DB experts) thus your machine
needs to be pretty powerfull. Thirdly, if you arrange your logs properly
and gzip (or bzip) them, then a few perl scripts can do all you want --
and they are not hard to write. If you want speed, then C and time is
all you need.

If you want logs on one central server, then why don't you mount a NFS
file store and write logs there. Or scp logs to a central log
repository?

As for log searches, how many do you *really* do?

Perl and NFS/scp would be what I would suggest. It's easier to
administer as well.
