[ http://jira.qos.ch/browse/LBCLASSIC-260?page=com.atlassian.jira.plugin.syste... ] Tomasz Nurkiewicz commented on LBCLASSIC-260: --------------------------------------------- Any updates on this issue? I guess more votes are required to consider incorporating it in Logback?
Recording appender that dumps debug messages only when error occurs -------------------------------------------------------------------
Key: LBCLASSIC-260 URL: http://jira.qos.ch/browse/LBCLASSIC-260 Project: logback-classic Issue Type: New Feature Components: appender Affects Versions: 0.9.28 Reporter: Tomasz Nurkiewicz Assignee: Logback dev list
Provide built-in utility appender that silently stores last few logging messages and dumps them (forwards to a target appender) only when an error occurs. Older logging events are replaced with new ones. This is a configuration example: <configuration> <appender name="REC" class="ch.qos.logback.classic.RecordingAppender"> <appender-ref ref="STDOUT"/> <maxEvents>1000</maxEvents> <dumpThreshold>WARN</dumpThreshold> <expiryTimeMs>15000</expiryTimeMs> </appender> <appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender"> <encoder> <pattern>%-4relative [%thread] %-5level - %msg%n</pattern> </encoder> </appender> <root level="DEBUG"> <appender-ref ref="REC"/> </root> </configuration> Such an appender is crafted manually by several users, it would be nice to provide it out of the box. I already implemented this feature (100% test coverage): https://github.com/nurkiewicz/logback/tree/recording-appender
