Incremental analysis

Hello,
when I try to do incremental analysis it says cache does not match. It then starts from the beginning. I have about 7 gigs of logs that are for several months. First why does it not match? Second if I have incremental set can I delete old logs since they have been analyzed?

Thanks,

Dennis

Your both questions are related to each other.
Usually Advanced Log Analyzer displays the message "Cache does not
match" when something was changed in configuration of reports.
In Advanced Log Analyzer you can add new reports, delete existing
reports or modify the reports. For example, you could have report
"Most visited pages" with checked "Only Pages" parameter. Then, for
example, you change one of the parameters of the report (for ex.
uncheck "Only Pages" parameter). Obviously produced data on the next
analysis will be not the same because of different report
configuration. So ALA should display the message: "Cache does not
match". It will delete the existing cache and recalculate the cache
file.

In your case if you do not change configuration of reports probably
it's an issue.

Could you please send us (support@abacre.com) your *.ini files and
probably put your zipped log file somewhere on your server so we will
be able to download it. Or just send zipped log file by email.

Technically: yes. You can delete your log files. But in this case you
should backup your cache files.

But In practice it's better if you hold your log files. For example in
future you may need to run some new reports over old log files.
What we usually do: We use cache file. But we archive old log files
using WinRAR: RAR files can handle very large files.
So for your case: 7 GB of logs will be compressed into one 165 MB RAR
file. And you may hold this 165 MB without any problems.
