The Diagnostics tab provides the diagnostics details timeline for ports, which includes transmit and receive traffic, and port utilization over time. By default, this timeline displays data for the last 24 hours, but you can change the time range by Day, Week, or Month, and for 1, 2, 4, 8, and 24 hour durations. Choose Day from the Time Range drop-down to see the event data in the timeline on an hourly basis. Choose Week or Month to see the data on a daily basis. You can also drag either side of the timeline to change it. Select = at the bottom right of this timeline to print it or to download it in a variety of file formats.
