Just for Information:
On Linux system I was using Google analytics, but on Linux system due to flash, analytics was not coming correctly. When I installed stat counter then it given me correct statistics, I got relief that some people are visiting my site.
It was the story created when I just started my blog.
For first 100 visits it is free. But you can reset your counter and start again.
It will give you all the facilities (various tracking, visitor path, length, keyword analysis/activity,..) which you need for your site.
