The hacker requests are in the hundreds, but they are still only a tiny percentage.
I ran with PROGRESSFREQ, and it turns out that on our server, Analog is taking about 80-100 seconds to read every million lines. It looks to be CPU-bound (75-85% CPU running at low priority). Removing my REQALIAS REGEXP lines (about 15 of them) speeded it up to about 50s/ML, so it looks like my aliases account for about half the slowdown. (Our database-driven site has a lot of scripts, so I really want to strip out some of the excess parameters). I could get further, to below 30s/ML if I took out FILELOWMEM 1 -- but then some of my attempts ran out of memory, so no good for now. With REGEXP but without FILELOWMEM the results were around 40s/ML. So ... definitely should add memory. CPU would be nice, but not a simple upgrade for that. But I'm going to adjust the reporting time to around 2 AM (from midnight) to make sure that I get a quiet time of day. Jean-Christian reported 30 minutes for 8 GB. If I assume 100 bytes per line (about the average for us), then it's 1800 seconds for 80 ML, or a little over 20s/ML. That makes sense given that he's running on a fast P4 system with lots of memory, surely without FILELOWMEM, and quite possibly without too many REGEXP lines. Something to strive for, I suppose ...

Look at the amount of mistrials you will find in your logfiles by those automatic hackers, mistrials caused by /default.ida /script/....... /cmd.exe /root.exe etc. etc. Fore some time it might be interesting for system managers to see what happens to their servers, to also analyse the 'dirt' in the logfiles, but after a while it gets annoying, if you realize that not having this dirt in your logfile might save you 1/3 of the size of your logfiles. Unless leaving it out in the analog process doesn't cost extra processing time........ Henk Schrik tel.
