The Microsoft 365 Exchange logs come in on UTC time format as many cloud providers use. So any activity needs to factor in the time difference for your timezone. Some parts of the dashboard only show data for the last 4 hours as cloud logs can generate massive volume of events. If longer search times are desired then its best to use the event search feature to search for logs over longer time period.
The specific log types in the widgets are for Microsoft Exchange Log Activity.
Exchange log Activity - shows a graph of log activity for today.
Exchange Log Activity by User - details the operations on a per user basis.
Exchange Admin by Operation - details the admin operations being performed by the users.
Some example of the dashboard items are below.
