I have the following logback.xml file:
<configuration debug="true">
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n</pattern>
</encoder>
</appender>
<root level="debug">
<appender-ref ref="STDOUT" />
</root>
</configuration>
Now, upon the occurrence of a specific event, I want to programmatically change the level of the root logger from debug to error. I can't use variable substitution, it is mandatory that I do this within the code.
How can it be done ? Thanks.
Try this:
import org.slf4j.LoggerFactory;
import ch.qos.logback.classic.Level;
import ch.qos.logback.classic.Logger;
Logger root = (Logger)LoggerFactory.getLogger(Logger.ROOT_LOGGER_NAME);
root.setLevel(Level.INFO);
Note that you can also tell logback to periodically scan your config file like this:
<configuration scan="true" scanPeriod="30 seconds" >
...
</configuration>
