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 -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira

[JIRA] Created: (LBCLASSIC-301) MDC Adapter with configurable InheritableThreadLocal

MDC Adapter with configurable InheritableThreadLocal ---------------------------------------------------- Key: LBCLASSIC-301 URL: http://jira.qos.ch/browse/LBCLASSIC-301 Project: logback-classic Issue Type: Improvement Components: appender Affects Versions: 0.9.28 Reporter: Alexander Treptow Assignee: Logback dev list Priority: Minor Attachments: LogbackMDCAdapter.java In our application we use a sifting file appender to log bot requests to a different log file than normal user requests. We have several sensor and aggregation threads that are started on different times that also have some logging output. My Problem: Log statements from request-independent threads are posted to bot.log and main.log on random. My Solution: I patched the LogbackMDCAdapter to be configureable by a system variable, to disable inheritance of the thread local member "copyOnInheritThreadLocal". The patched version defaults to old behavior, so it doesn't change if you do not configure it. To disable inheritance of that member, just pass "logback.threadlocal.inherit.copy=false" to the JVM. I applied the patch to Version 0.9.28 and tested it with our application. Maybe other logback users also want to configure logback in that way. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.qos.ch/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
