Hi,
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.
