I do not agree on that.
Let's say you have a 2 GB log file per month. You have to run analog 30
times on this file. This means that analog parses the 2GB file 30 times
(because analog do not presume that lines are ordered by date in log files -
I _hope_ I'm wronk on that).
Of course you can break the file in 30 chuncks (with bash, perl, etc) and
run analog 30 times on coresponding chunk and then build up the result file
from the partial result files.
And now to have the full picture of the mess, let's say you have 30
web-sites with thousands of visitors.
I agree with Claudiu Costin: the user should decide how much mem demanding
the log processing will be.
with respect,
