im current using SARG to analyze my 180+ on my proxy server here in my office, wondering if you guys here have any suggestion on other software for this.

Sorry mate..
Usually I would just take a glimpse at the access.log..
SARG is a good software by itself..

I did use SRG before too.. I figured it's pretty good too.

I took a look at the sample reports on SARG's website, and found that it's largely similar to that provided by Calamaris.

use webalizer also not bad, including some chart image and some other imformation. but sarg is good too.
