Issue - "Visitors" metric collected from Piwik to Looker Studio


I’m working on a Looker Studio for a client and collecting data from my Piwik Pro client account.

The issue is that I have differences between data collected by month and the grand total line for visitors.

Here is an example:

Can you please give an explanation about how this metric is calculated?

For your information, I collected 89,615 visitors in Piwik Pro during the same period for every report.

Best regards,


Hi @Arthur!
