Global flags

Global flags are not command specific.


--config · Default: empty

Overrides the configuration file.

gremlins <command> --config=config.yml


--silent/-s · Default: false

Makes Gremlins work in silent mode, which means only errors will be reported on STDOUT. This is useful in CI runs when you don't want to clutter the log, but just read the results from a file or check the exit error code in combination with a threshold configuration.


Note that Gremlins will be completely silent if there aren't errors, it doesn't mean it is unresponsive.

gremlins <command> --silent
