Microsoft 365 reports - groups activities

Item Description
The Microsoft 365 groups report can be viewed for trends over the last 7 days, 30 days, 90 days, or 180 days. However, if you select a particular day in the report, the table (7) will show data for up to 28 days from the current date (not the date the report was generated).
The data in each report usually covers up to the last 24 to 48 hours.
The Groups view shows a total number of groups that existed on any given day, and active groups on that day based on Email Conversations, Yammer Posts and SharePoint file activities and SharePoint pages viewed.
The Activity view shows you the number of group activities across group workloads. You can view the Exchange emails received by the group mailboxes across all groups, on any day during the reporting period. You can also see messages posted, read, and liked across the Yammer groups associated with a group.
The Files view shows you the number of total and active files across all group sites associated with a group.
The Storage view shows you the total storage used across all group mailboxes and group sites.
On the Groups chart, Y-axis is the number of groups (which can be seen as total vs active).
On the Activity chart, Y-axis is the number of times an activity was performed in groups.
On the Files chart, the Y axis is the number of either total or active files.
On the Storage chart, the Y axis is total storage used by the group mailbox or site.

You can filter the series you see on the chart by selecting an item in the legend. For example, on the Groups chart, select Total or Active Total and Active number of groups to see only the info related to each one. Changing this selection doesn't change the info in the grid table.
