Answers to Frequently Asked Questions

What is 123LogAnalyzer and what can I do with it?
123LogAnalyzer is a powerful online Windows tool that turns your web logs into a comprehensive and easy to read analysis of your customers and prospects. 123LogAnalyzer tells you how visitors browse your web site, which pages they view and which they ignore, how long they spend on your site, and where they come from.
123LogAnalyzer's web server activity report displays the number of visitors, the number of unique IP addresses, the amount of bandwidth used, and the number of hits the site received, broken down by time increment, day of the week, and hour of the day. To learn more about the information that visitors accessed, you can see which web pages were viewed, files were downloaded, directories were accessed, and images were looked at.
Referrer information includes the domains and URL's that the visitors came from. The search engine performance report displays the search engines which referred visitors to the site, and the words and phrases that visitors searched for. 123LogAnalyzer provides geographic information about your visitors, as well as what platforms and browsers people are using to visit your site. You can even identify missing files, broken links, and other errors that visitors encountered.
With its advanced filter options, 123LogAnalyzer lets you examine only those visitors who went to specific pages, or who downloaded particular files. You can also zero in on visitors who came from particular URL's, specific countries, or who visited at certain hours of the day.
123LogAnalyzer's power lies in its ability to combine filters to extract specific information. For example, not only can you see how many visitors visited the "BuyNow" page, but you can also see what other pages these people viewed, what their browsing sequence was, how many files they downloaded, what domain they came from, and what search engine keywords they used to get to your web site. Armed with this information, your can fine-tune your web site to be a more effective sales machine.
123LogAnalyzer runs on your client Windows 95/98/NT4/2000 PC, and places no burden on your host's web server. Its intuitive interface requires absolutely no technical knowledge whatsoever. The program supports and auto-detects major web server log file formats on both Windows and UNIX platforms.
The program produces reports in real-time. On a 800Mhz PIII computer running Windows 2000, it can analyze 94,000 lines of log file data per second, or a little over 1GB of data per minute.
In the short term, 123LogAnalyzer pinpoints new opportunities to attract more visitors and customers by telling you which of your web pages are working and which aren't. In the long term, the program lets you understand shifts in visitors' browsing and buying behavior, and gives you all the information you need to give your web site a sales tune-up.

What are log files? Where can I find them? How do I use them?
Log files are files that contain a record of website activity. Every time a person visits your website, a log file is updated with the visitor's information by the web server. These log files can be downloaded and used to generate useful statistics.
123LogAnalyzer can analyze these log files and tell you how visitors browse your web site, which pages they view and which they ignore, how long they spend on your site, and where they come from.
These log files are usually available from your Internet Service Provider (ISP). If your web site is hosted by an ISP, you should contact them for details of how to access your web log files.
If you host your web site by yourself. you can check your web server documentation for where log files are located.
If you need us to help you access your web log files, please feel free to email

What log file formats does 123LogAnalyzer support?
123LogAnalyzer supports major web server log file formats on both Windows and Unix platforms, such as:

  • Apache common and combined log file format
  • NCSA common and combined log file format
  • Microsoft IIS4/IIS5 W3C extended log file format
  • Sun/Netscape iPlanet log file format
  • Lotus Domino web server log file format
  • Oracle web server log file format
  • and more...

What are your definitions of hits, visitors, unique IPs, page views?
An access of a web page or a file will generate a "Hit" on the web server. For example, if a web page contains 10 pictures, a visit on that page will generate 11 "hits" on the web server, one hit for the web page, 10 hits for the pictures.
If a visitor viewed 5 web pages on the web site, each page contain 10 pictures, the web server will record:

  • 55 Hits
  • 5 Page Views
  • 1 visit

If the visitor left the web site and came back 30 minutes later, 123LogAnalyzer will report 2 visits. If the visitor came back within 30 minutes, 123LogAnalyzer will still report 1 visit.
A unique user (with unique IP address) is determined by the IP address. By default, a visit session is terminated when a user falls inactive for more than 30 minutes. So a unique user (with unique IP address) may visit your web site twice and get reported as two visits.

Can I check if certain IP's are abusing our site?
Yes. 123LogAnalyzer provides report of detailed IP addresses of those who accessed your web site with the most hits or with most bandwidth. So you can find out who's abusing your web site. You can even use the filter feature to narrow down the candidates. Not only can you see their IP addresses in the report, but you can also see who own those IP addresses, allowing you to contact the network administrators and report network abuses.

Can I find out who has been visiting my web site?
Yes. 123LogAnalyzer provides report of detailed IP addresses of those who accessed your web site, broken down by visit time, hits and bandwidth. You can also find out who owns specific IP address.

Generally, the report files are stored under "C:\Program Files\123LogAnalyzer\Report\" folder, the file names are p0.htm to p8.htm

Why can't I get search engine analysis or referrer analysis?
The reason for this problem is that the log file does not contain enough information for 123LogAnalyzer.
If the web server is Unix/apache server, the log file may be in "common" format which does not contain referrer and browser information. To add this information, a "combined" log file format should be used.
A "common" log file format is like this: - - [01/Oct/2001:11:39:55 +0000] "GET /sample/ HTTP/1.1" 200 247
A "combined" log file format is like this: - - [01/Oct/2001:11:39:55 +0000] "GET /sample/ HTTP/1.1" 200 247 "http://www.123loganalyzer.com/" "Mozilla/4.0 (compatible; MSIE 5.5; Windows 98; Win 9x 4.90)"

If the web server is Microsoft/IIS web server, in log file properties section, referrer and User Agent properties should be checked in order to provide referrer and browser information. A IIS log file with referrer information should be like this:
#Software: Microsoft Internet Information Services 5.0
#Version: 1.0
#Date: 2001-10-24 00:06:23
#Fields: date time c-ip cs-username s-ip s-port cs-method cs-uri-stem cs-uri-query sc-status sc-bytes cs(User-Agent)
