Traffic Sampling Output Files

Traffic sampling output is saved to an ASCII text file. The following is an example of the traffic sampling output that is saved to a file in the /var/tmp directory. Each line in the output file contains information for one sampled packet. You can optionally display a timestamp for each line.

The column headers are repeated after each group of 1000 packets.

To set the timestamp option for the file my-sample, enter the following:



[edit forwarding-options sampling output file]
user@host# set filename my-sample files 5
size 2m world-readable stamp;

Whenever you toggle the timestamp option, a new header is included in the file. If you set the stamp option, the Time field is displayed.
