Jinja2 templates are used to translate the JSON output from benk to a desired data structure. TSV and CSV are simple to paste into a spreadsheet. For more comprehensive, structured and automated benchmarks, SQL or any other database may be more practical. | ||
|
||
This log entry may be used as a boilerplate to write templates. The outputter from benk provide different set of variables to Jinja depending on if it's a single log file being processed or two. Check out the example templates for details. | ||
