Actually you don't even need Goaccess running all the time. They parse nginx logs directly so you can only run it when you want to do it (although in practice it takes sometime to parse and create graphs).
I would contend the contrary. Our company consistently runs GoAccess because we are primarily concerned with unusual traffic patterns. This involves monitoring for potential attacks or abnormal bot traffic that might impact our servers, etc.
While JS analytics tools might be of more interest to the marketing team, they are not as crucial for the devops team.
