Rajini Sivaram created KAFKA-7237: ------------------------------------- Summary: Add explicit fatal marker to fatal error messages Key: KAFKA-7237 URL: https://issues.apache.org/jira/browse/KAFKA-7237 Project: Kafka Issue Type: Bug Components: core Reporter: Rajini Sivaram
We currently use FATAL markers for fatal error messages in core. But only logback supports markers out-of-the-box and log4j simply logs these as ERROR messages, ignoring the marker. We should perhaps include a String marker within these messages to make it easier to identify fatal messages in logs. >From https://www.slf4j.org/faq.html: While markers are part of the SLF4J API, only logback supports markers off the shelf. For example, if you add the {{%marker}}conversion word to its pattern, logback's {{PatternLayout}} will add marker data to its output. Marker data can be used to [filter messages|http://logback.qos.ch/manual/filters.html] or even [trigger|http://logback.qos.ch/manual/appenders.html#OnMarkerEvaluator] an outgoing email [at the end of an individual transaction|http://logback.qos.ch/recipes/emailPerTransaction.html]. In combination with logging frameworks such as log4j and java.util.logging which do not support markers, marker data will be silently ignored. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
