I. Introduction

Filters hold the key to unlocking the power of Nihuo Web Log Analyzer. Understanding how filters work will help you to get the most out of your
reports. Filters allow you to limit the scope of Nihuo Web Log Analyzer’s analysis to specific parts of your site, providing only the most important information in reports to make reports more readable or relevant.

II. Why should I filter data?

Filtering or excluding certain data from your reports is important to ensure your data reports are accurate. If you want to measure performance
of your promotion plan and you do not set up any filters, all those visits from your web team are going to have a negative effect on the reported data. Generally it is a good idea to filter as many known people and domains as possible to ensure the reported data is as accurate as possible.

You can create extra profiles of the same website and filter specific traffic to only appear in all reports of that profile.

III. Hit Filter & Visit Filter

Nihuo Web Log Analyzer provides two filter types: Hit Filter and Visit Filter.

Hit filters include or exclude raw data generated by individual actions on a web site.

Visit filters include or exclude all the data in a visitor session.

Multiple filters can be combined in a profile with boolean operator ( AND, OR , NOT ).

Here’s the correct list for all the currently available filters and how Nihuo categorizes them.

1. Hit Filter

• Authenticate User
• Browser
• Client Host Country

• File Type
• HTTP Method

• Referrer
• Requested File
• Return Code
• Spider
• Stolen Object

2. Visit Filter

• Visitors with specified exit page
• Visitors who came from specify referrer
• Visitors who accessed specified file

IV. Wildcards

Nihuo Web Log Analyzer support using wildcards in hit parameters.

Here are the wildcards supported by Nihuo Web Log Analyzer:

1. An example using *

Let’s say you want exclude all files and subdirectory below /admin/ from reports.

Just create exclude Requested File hit filer and input below parameter:

2. An example using ?

Let’s say you have several files on your website:

Let’s say we use this wildcard file name:

The ? matches a single character. The wildcard file name above means

“match any filename which starts with file, is followed by a single character, and then the .htm extension follows”. This wildcard will select:

… but it will NOT select:

because it has two characters, instead of one, between file and .htm.

But if you specify the wildcard:

then only

will be selected, because the wildcard file name specifies that there must be 2 characters between file and .htm

1. Create a new page on your domain, containing the following code:
   < script > function SetCookie(cookieName, cookieValue, nDays) {

   var today = new Date();

   var expire = new Date();

   if (nDays == null || nDays == 0)
   nDays = 1;

   expire.setTime(today.getTime() + 3600000 * 24 * nDays);

   document.cookie = cookieName + “=” + escape(cookieValue) +
   “; expires=” + expire.toGMTString();

   }

   </script>

   (Please note you must ensure cookie field had been exported in log files.)
