Hi @lou,

can you make sure your target platform contains the 4.0.1 bundles? There was a regression in KNIME 4.0 that swallowed log messages from third party plugins.

To use NodeLogger you just need to get the instance for your class:

github.com

knime/knime-examples/blob/master/org.knime.examples.numberformatter/src/org/knime/examples/numberformatter/NumberFormatterNodeModel.java#L47


*
* @author KNIME GmbH, Konstanz, Germany
*/
public class NumberFormatterNodeModel extends NodeModel {

	/**
	 * The logger is used to print info/warning/error messages to the KNIME console
	 * and to the KNIME log file. Retrieve it via 'NodeLogger.getLogger' providing
	 * the class of this node model.
	 */
	private static final NodeLogger LOGGER = NodeLogger.getLogger(NumberFormatterNodeModel.class);

	/**
	 * The settings key to retrieve and store settings shared between node dialog
	 * and node model. In this case, the key for the number format String that
	 * should be entered by the user in the dialog.
	 */
	private static final String KEY_NUMBER_FOMAT = "number_format";

	/**
	 * The default number format String. This default will round to three decimal

Then call the log methods on it. You might need to set the appropriate log level in the KNIME AP preferences to show all message types:

knime-setting

best,

Can you let it resolve and then confirm that your version of KNIME Core is also 4.0.1?

I want to see the log in Eclipse(not Knime) console output with the following setting

<logger name="com.gw">
        <level value="all" />
        <appender-ref ref="stdout" />
        <appender-ref ref="stderr" />
        <appender-ref ref="knimeConsole" />
    </logger>

com.gw is my package prefix,It’s correct? but i just see log in runtime-KNIME.metadata\knime\knime.log there is no log in Eclipse console.

any suggestion? thanks
