How to track User logged on to the site (by username)

I am new to Piwik. It’s an interesting web analytic application but i am not much familiar with its functionality. Can anybody please tell me how i can track username of visitors who are logging in to my website I want to track the user logged in by their username. Is here any way to track this? Can i do it by custom variable? or to do it by custom variable ?

use Custom Variables: Custom Variables Analytics - Analytics Platform - Matomo

use Custom Variables:[/quote]

Can you please help me to code custom variable for this purpose. Here is what i am thinking to implement, is it okay?
1, // Index, the number from 1 to 5 where this custom variable name is stored
"login", // Name, the name of the variable, for example: Gender, VisitorType
"username", // Value, for example: “Male”, “Female” or “new”, “engaged”, “customer”
“visit” // Scope of the custom variable, “visit” means the custom variable applies to the current visit

Can you please let me know, Is this code work to know the username of visitors?

I’ve been looking for something like this. I have a very simple blog in Tumblr. But I am not contented with what I see in Google Analytics, I’d like to see something more specific. Can I use the article you posted? Thank you so much. :slight_smile:
