Custom variable and userid not displaying- importing from logs

I am new to piwik. Can anyone suggest me the correct log format. Please find the below sample logs.
I am not getting the ‘user’ and ‘cvar’ values. please suggest me what i am doing wrong? Did I need to make any changes in python script?

Kindly help to import the below logs? I am not getting any error. - - [24/Mar/2014:05:58:10 +0000] “GET /piwik.php?
uid=SampleUser&cvar=%7B%221%22%3A%5B%22SEARCH_STATUS%22%2C%22OK%22%5D%7D HTTP/1.1” 200 54 “Mozilla/5.0 (Windows NT 6.3; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/34.0.1847.116 Safari/537.36”
