[ http://jira.qos.ch/browse/LBCLASSIC-312?page=com.atlassian.jira.plugin.syste... ] Dmitrius Listo commented on LBCLASSIC-312: ------------------------------------------ UPD. Just tried to substitute ${LOG_PATTERN} into sifted appender. Got "LOG_PATTERN_IS_UNDEFINED" instead of log statements. It looks like property substitution inside sifted uppender is broken at all.
SiftingAppender does not substitute variable value inside sift --------------------------------------------------------------
Key: LBCLASSIC-312 URL: http://jira.qos.ch/browse/LBCLASSIC-312 Project: logback-classic Issue Type: Bug Components: appender Affects Versions: 1.0.0 Environment: Ubuntu 11.04, Eclipse 3.7 Reporter: Dmitrius Listo Assignee: Logback dev list Attachments: log.txt, logback.xml
Faced a probable bug (at least, did not find any mention about such issue at manual/google/other bugs in category). Brief logging configuration description: I have a property defined in my logback configuration. There is a property with log file location defined: <property name="LOG_HOME" value="/tmp/aicore" /> Also, I have ConsoleAppender and two RollingFileAppender appenders, attached to root logger. RollingFileAppender configuration contains LOG_HOME variable in path and substitution is done without any issues, log file is created and updated. But when I add SiftingAppender (log files are created on per-threadId basis), that contains FileAppender in it's sift section, variable value is not substituted. Here is the logback log fragment, generated using OnConsoleStatusListener: 22:11:27,396 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.FileAppender] 22:11:27,396 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [FILE-server] 22:11:27,398 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Assuming default type [ch.qos.logback.classic.encoder.PatternLayoutEncoder] for [encoder] property 22:11:27,400 |-INFO in ch.qos.logback.core.FileAppender[FILE-server] - File property is set to [LOG_HOME_IS_UNDEFINED/thread-server.log] Note the "LOG_HOME_IS_UNDEFINED/thread-server.log" value. As a result, no any sift log file is created in expected location. When I substitute ${LOG_HOME} value manually, everything works well. Below is my SiftingAppender config: <appender name="SIFT" class="ch.qos.logback.classic.sift.SiftingAppender"> <discriminator class="ch.qos.logback.classic.sift.MDCBasedDiscriminator"> <key>threadId</key> <defaultValue>unclassified</defaultValue> </discriminator> <sift> <appender name="FILE-${threadId}" class="ch.qos.logback.core.FileAppender"> <file>${LOG_HOME}/thread-${threadId}.log</file> <append>false</append> <encoder> <pattern>%d [%thread] %level %mdc %logger{35} - %msg%n</pattern> </encoder> </appender> </sift> </appender> Sorry if bug report is not formed perfectly, I have not much expertise yet :)
