log-level

The --log-level parameter controls the amount of messages that are generated when running Liquibase commands. The --log-level can be set to the following values:

  • SEVERE (highest level) – Show serious failures that may prevent program execution.
  • WARNING – Show potential problems for program execution.
  • INFO – Show informational messages.
  • FINE (lowest level; formerly DEBUG) – Show tracing information of program execution and minor failures.
  • OFF – Hide all log messages.

If you set --log-level to a particular level, it will show all messages at that level and at higher levels of importance.

The --log-level default value is OFF. However, if you use the --log-file attribute to send your logs to a different file and don't specify the --log-level parameter, Liquibase will automatically change the --log-level default value from OFF to SEVERE.

Uses

The --log-level parameter applies to all Liquibase commands. It can be used to get more information about the actions that Liquibase commands perform, as well as provide helpful information to resolve errors.

The default value of SEVERE provides messages regarding serious errors. You may find it useful to set the --log-level to INFO to see a more complete list of the operations that a command performs. Use the FINE level to help resolve errors.

Using the --log-level parameter

The --log-level is an optional parameter that is either set in the Liquibase properties file or specified on the command line. The --log-level specified on the command line overrides the value set in the properties file.

Examples:

liquibase --log-level=FINE update
liquibase --log-level=INFO update-testing-rollback
