Hi Andrew, Thanks for the tip. However, I should have been more clear. I really *do* want to change the logging level. Deployment&maintenance is done by third party, hence they decide what should be visible at each level (wish that wasn't the case, but...) Also, it means removing the appender for some cases, e.g.if I want to 'upgrade' an error to WARN & add a specific 'WARN' appender, it works. However, when I only want to see ERROR I also have to remove the appender. Now I know that, but as said, maintenance is not done by me...

If that's the case, you can simply declare a separate logger for the packages of that third-party library. In Groovy configuration that gives us: import ch.qos.logback.classic.encoder.PatternLayoutEncoder import ch.qos.logback.core.FileAppender import static ch.qos.logback.classic.Level.* appender("someAppender", FileAppender) { file = "/var/log/test/rootLog.log" encoder(PatternLayoutEncoder) { pattern = "%date{yyyy-MM-dd HH:mm:ss,SSS} [%thread] %-5level - \\(%logger\\) - %message%n" } } root(ERROR, ["someAppender"]) // ======================================================= // This is the logger that will allow WARN messages of your third-party library to log its WARN messages (and above) to the same appender the rootLogger is using. // "logger(...)" documentation can be found here: http://logback.qos.ch/manual/groovy.html // ======================================================= logger("com.thirdparty.lib", WARN, ["someAppender"], false) Best regards Andrew Bourgeois From: K.O.Gadellaa@rn.rabobank.nl<mailto:K.O.Gadellaa@rn.rabobank.nl> Sent: Friday, 07 September, 2012 18:24 To: logback-user@qos.ch<mailto:logback-user@qos.ch> Subject: [logback-user] Modifying a logging events' level Hi, I'm in the situation where a 3rd party code logs some content at a certain level, but I want that log to be a different (higher) level. E.g: in my log: WARN : Connection to XYZ failed. But I want: ERROR: Connection to XYZ failed. Is there a way to do this with logback? (couldn't figure it out... maybe with a separate appender?)
