The simplest and most effective way to use cachefiles is to create a
seperate cachefile for each logfile. Then, when you want to create a
weekly or monthly report, run Analog against just the cachefiles.
So everyday I create new cache, e.g. cache1.db, cache2.db, etc. until
cache31.db and then when running the monthly analog process I define
in the appropriate config all those 31 cache??.db files with CACHEFILE
directive? Is this what you are advising me?
I'd advise that you don't use cache files at all - they can be confusing,
and severely limit the flexibility of Analog (you can't reliably modify your
reports if they are based on cache files). Therefore you shouldn't use cache
files until you have been using Analog long enough to be entirely satisied
with your Analog reports, and that you won't be changing them.
The simplest error that you can make with cache files is to include the same
information twice in the cache file when making a cumulative cache file. The
simplest way to avoid this is to create a cache file for each logfile.

Alternatively, you can also run Analog against yesterdays cachefile
and yesterdays logfile to create a new cachefile that you will use
with todays logfile, etc. But if you're not careful, you can end up
counting the same traffic multiple times.
Can you show me example on how to do this?
Not really - I've never used cache files, so if the description above
doesn't make sense, I'd rather not make it any more detailed. Deleting
logfiles involves throwing data away, and I don't want to offer advice that
might cause problems further down the road.
Unless you're dealing with several gigabytes of logs per day, simply
zipping your logs may be a more effective way to solve whatever
problems you were having in the first place.
This will be done only in case I cannot figure out how to do it with
analog without the need to keep all the logs.
You haven't said why you want to get rid of the logs. How big are they? How
long are your reports taking to run?
