logLevel parameter

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

• off
• severe
• warning
• info
• debug

The logLevel 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 logLevel parameter, Liquibase will automatically change the logLevel default value from off to severe.

Uses

The logLevel 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 logLevel to info to see a more complete list of the operations that a command performs. Use the debug level to help resolve errors.

Using the logLevel parameter

The logLevel is an optional parameter which can be set in the liquibase.properties file or specified on the command line. The logLevel specified on the command line will over-ride the value set in the liquibase.properties file.

Examples:

liquibase --logLevel=debug update

liquibase --logLevel=info updateTestingRollback
