Modifing MDCPropertyMap of LoggingEvents
by Cemo 17 May '15

17 May '15

I have a layout which is generating JSON from logging events and MDC Context. MDC is great and I want to add parameters to MDC Context conditionally. For example, I would like add request information as JSON into MDC conditionally on Error Level log entries. I am not familiar with Logback internals but gave a try with Logback Filter implementation. I have used: public FilterReply decide(ILoggingEvent event) { // simplified for demo // conditionally I am putting some attributes here Map<String, String> mdcPropertyMap = event.getMDCPropertyMap(); if (event.getLevel().isGreaterOrEqual(Level.ERROR)) { mdcPropertyMap.put("demo", "demo"); } return FilterReply.ACCEPT; } I am expecting mdcPropertyMap to be cleared for each event but it does not. LoggingEvent has a internal CACHED_NULL_MAP map and its modified per touch. private static final Map<String, String> CACHED_NULL_MAP = new HashMap<String, String>(); I could not be sure but it seems a little bid buggy to me. Can someone verify this behaviour? For those who are interested why I am not using MDC.put in a Servlet Filter implementation because I am conditionally adding some attributes. Serialising HttpRequest into JSON is not cheap task but having Http Request information is giving great insights about error. Using Filter is the only way I found to add conditionally attributes so far. What I would like to use is: public FilterReply decide(ILoggingEvent event) { if (event.getLevel().isGreaterOrEqual(Level.WARN)) { MDC.put("demo", "demo"); } return FilterReply.ACCEPT; }

Change log level in websphere
by Fabiano, Lucas 30 Mar '15

30 Mar '15

Hi guys, Sorry for my english. I’m have difficult to determine the best way to change the log level in production. We have Websphere 6 and 8. With JMX, production team doesn’t allow because it conflicts with the monitoring tool. I was trying to use the auto reload functionality but for the production team if I need to deploy even a single file it’s considered as I changed the application package and needed to create a deploy request and it only can be done at midnight. I need to have the ability to change the level in production in a quick way just like JMX but something that works on websphere. I’m still researching about this but I’m not positive if I can go ahead with this solution. Can you share ideas with me?

Logback ClassOfCallerConverter failure for org.slf4j.ext.LoggerWrapper descendants
by USHAKOV, Sergey 08 Mar '15

08 Mar '15

Hi, I have currently come across an issue that if a org.slf4j.ext.LoggerWrapper subclass is used as logger in combination with Logback, then any logging methods inherited from it are prevented from location information being logged: class, method and line number are all replaced with question marks. Only methods overridden by a subclass are logged correctly. The reason seems to be that ch.qos.logback.classic.spi.ClassOfCallerConverter#isInFrameworkSpace() method only recognizes "org.slf4j.Logger" and "org.apache.log4j.Category" as appropriate stack trace delimiters, and "org.slf4j.ext.LoggerWrapper" fails to be recognized. My guess is that "org.slf4j.ext.LoggerWrapper" should be allowed to serve as stack trace delimiter somehow, be it explicitly by class name or implicitly by package name, or any other way... Does it look like a minor bug in Logback with respect to LoggerWrapper? Or if I am mistaken, please advise of any other appropriate way to get location information from org.slf4j.ext.LoggerWrapper ... Thanks and best regards, Sergey

NPE when configuring AsyncLogger in logback.groovy after using logback.xml -> logback.groovy conversion tool

Hi All Versions used: Java: 1.8.0_25 logback-core/classic: 1.1.2 groovy-all: 2.4.1 I hope somebody can help.
