What do the colors mean on the Activity Record pane?
There is a legend on the right of the pane that shows which colors are used for the different event types: logins and syncs. The graph does not show when the user logged out. Some of the items in the legend are marked with an “*”. The note at the bottom of the pane explains that these are for “off-hour” events. Items are flagged as off-hour if they occur outside of 9:00 AM – 5:00 PM, Monday-Friday based on the server timezone. This is only a very rough measure of whether the item was off-hours because it does not take into account the timezone of the user and the work hours of the user.
