Update time since the user leaves the website

Update time since the user leaves the website

Hi,  

I have a question about the operation of the display panel of online visitors

Can we configure the update time since the user leaves the website? 

I have verified that the time of update since a visitor leaves the web until it disappears from the panel is 1 minute, I think it is a long time. Can we modify the configuration so that the info is updated faster? 

Thanks!
