dagster debug¶

Commands for helping debug Dagster issues by dumping or loading artifacts from specific runs.

This can be used to send a file to someone like the Dagster team who doesn’t have direct access to your instance to allow them to view the events and details of a specific run.

Debug files can be viewed using dagster-webserver-debug cli. Debug files can also be downloaded from the Dagster UI.

dagster definitions validate¶

The dagster definitions validate command loads and validate your Dagster definitions using a Dagster instance.

This command indicates which code locations contain errors, and which ones can be successfully loaded. Code locations containing errors are considered invalid, otherwise valid.

This command returns an exit code 1 when errors are found, otherwise an exit code 0.

This command should be run in a Python environment where the dagster package is installed.
