Using traffic analysis to check from 4 months to current

Hello

With one of the SEO meterics providers stats I use not seem to be budging while all others keep climbing I decided to try and check the logs to see if I could find the last time “rogerbot” came past my site.

The ffilter I am trying to apply for the date ranges does not seem to allow me to click on any dates in the in the past.

Basically all I am trying to do is see if rogerbot has come to my URLs in the past 4 months as I beleive its not becuase I am not seeing in my local firewall either.

Is there a right and wrong what to find out what user agents have been on a website in for a 4 month period. The calender numbers and not clickable for me for when I try to go back more than a few days using the filter.
