By default, Tsung use its own format (see FAQ What is the format of the stats file tsung.log?).
Since version 1.4.2, you can configure Tsung to use a JSON format; however in this case, the tools tsung_stats.pl and tsung_plotter will not work with the JSON files.
To enable JSON output, use:
<tsung backend="json" ...>
Example output file with JSON:
