The History tab of the Cache Monitor provides a graphical view of information about a selected cache.
If you select One Day from the Period list, the available data points in the previous 24 hours are retrieved (based on the server time). If you select One Week or Two Weeks, only every fourth data point is retrieved (1/4 points). Assuming the values are measured every 15 minutes, this results in a measurement once per hour.
