Quick question from newbie about web log

[preenet]

Hi all, I am wondering how to know the time the bots spend in my site like this?

IP Address 216.239.46.239
Reverse DNS crawl9.googlebot.com
From / Via Biznessonline
Origin Location New York, USA.
Time Spent 12 min
Hits / Kilobytes 1 / 2.64Kb
Browser Tag Googlebot/2.1 (+http://www.googlebot.com/bot.html)

I have a log file but it doesn't show just like above one. Anyone have idea? thanks

Hi Preenet.

To work out how long a visitor (or spider) has spent on your site, you need to add up the time between all their requests, until they stop asking for pages on your site. It depends a lot on what logs you have and what program you use to interpret them.
