Thanks for your fast reply. The tip for the report helps a lot. I’m now able to view a line based overview of traffic/transaction over a period of time.
I’m still unsure about which Office 365 traffic belongs to which cloud application/category. I have created a own URL category with the link from mentioned by @Naresh_Kumar_PM for OneDrive but it’s also includes a lot of SharePoint resources. I think OneDrive for Business is build on top of SharePoint and it’s maybe impossible to divide the Traffic. Unfortunately you can’t have a line chart with URL Category as filters.
Do you also now what is in the Cloud Application Microsoft Team included? All action inside Team, also like meetings and file activities? Or belongs so action to Skype/SharePoint.
