To see the current File system activity in graph form, click Tools > Watch activity. At the bottom of the graph is a timeline that records file system activity in real-time based on the selected time span. To change the time span, select from Refresh rate drop-down menu.
The following options are available:
•Step: 1 second – The graph refreshes every second and the timeline covers the last 10 minutes.
•Step: 1 minute (last 24 hours) – The graph is refreshed every minute and the timeline covers the last 24 hours.
•Step: 1 hour (last month) – The graph is refreshed every hour and the timeline covers the last month.
•Step: 1 hour (selected month) – The graph is refreshed every hour and the timeline covers the last X selected months.
The vertical axis of the File system activity graph represents read data (blue) and written data (red). Both values are given in KB (kilobytes)/MB/GB. If you mouse over either read data or written data in the legend below the graph, the graph will only display data for that activity type.
