You can set MettleCI Workbench to log more verbose diagnostic information in two ways:
Semi-permanent Method
You can add a line to your MettleCI config.yml. This file is typically located at /dm/mci/cofig.yml UNIX or C:\dm\mci\cofig.yml WINDOWS.
To enable verbose logging, add the following lines within the logging: section in your config.yml file:
loggers: com.datamigrators.mettle.process.CommandRunner: DEBUG
You will need to restart your Workbench service for extended logging to begin. To disable extended logging simply remove the lines above from your config.yml file and restart your Workbench service again.
Temporary Method
You can send a REST call to the Workbench to increase the logging level for the current session without changing your configuration:
curl -X POST -d "logger=com.datamigrators.mettle.process.CommandRunner&level=DEBUG" http://your-engine.your-domain.com:8081/tasks/log-level
This increases the Workbench logging level until the Workbench service is next restarted, at which point the log reverts the settings defined in config.yaml.
