By default the command will retrieve coverage information for the first 1000 builds. That can be changed by specifying --limit option. Additionally, you can provide optional parameters such as branch, start date, end date to filter the results. For example:

kci-dev maestro coverage --start-date 2025-09-01

Use --help option to list all the optional arguments.

You can also generate a bar graph to get coverage information visualization. It can be retrieved by using --graph-output option. For example:

kci-dev maestro coverage --start-date 2025-09-01 --graph-output

The command will generate a graph per branch. The bars will show function and lines coverage against different build commits. You can see the coverage report URL by hovering on the bars. Click the link to download the report or open it in your browser.
