Using qmailanalog on a big system

[melo]

Hi!

I'm running a relativelly large qmail system: 2 servers, each one outputs 1Mb
of cyclog logs each 5 minutes...

I would like to use qmailanalog to have some statistics (mainly total
deliveries and histogram of deliveries per time interval), but saving the
logs for a full day would take a lot of space.

Is there any way to use qmailanalog to generate such stats without storing
all the logs for the day and then running qmailanalog stuff over it?

Thanks in advance.
