Even you do not use or analyze your application usage or user patterns for know you may need them in the feature. Even today you will be very surprised when you see tracking results. For example; Do you know how often google bots comes to your site? Which user use which feature or pages?
We must track and analyze our applications and users . At least we need to collect them now.
I will present very very simple solution. You only need add binary to your bin folder and add 2 lines to web.config.
If you need too track application specific information just put them in the httpContext that’s all.
Ok let's begin.
That's all. What you will get is like this
Every request logged per line, name value pairs delimited with tab character and name and value delimited with ‘|’ pipe character. To avoid collision default names prefixed wit “_” underscore.
Default tracking parameters are limited because I did not want to depend anything.
In your application if you want to track any information.
just put information into HttpContext’s items in as blow. Prefix names with “track:” this is vital because library check if item name prefixed with “track:”
This is just a sample
HttpContext.Current.Items["track:controller"] = controllerName;
1 using System;
2 using System.Collections;
3 using System.Diagnostics;
4 using System.Web;
5 using System.Text;
