In this recipe we will learn how to get general information about the data that runs over the network.
To use the Summary tool from the Statistics menu, follow the ensuing steps:
- From the statistics menu, choose Summary.
What you will get is the Summary window (displayed in the following two screenshots).
- As shown in the following screenshot, in the upper side of the window, you will see:
- File: This part of the window provides file data, such as file name and path, length, and so on
- Time: This part on the window displays the start time, end time, and duration of capture
- Capture: This part of the window shows on which interface the file was captured and also displays a remark window
- In the lower part of the window is the Display window, where you will get a summary of the capture file statistics; this includes:
-
