There's a unique usage report that is called Searches by Time. It shows searches that were performed in the past 14 days only. It shows them by the hour and also they are based on usage groups. An example is shown below:

• Some customers may find it useful in determining a trend of usage based on the hour. This may help out in planning for resources. 
• It may point out to a specific time of heavy usage that may have led to an abuse of usage. 

**It can be accessed via ProQuest Administrative Account then choosing Usage Reports area.
