Masha Buka created LOGBACK-1432: ----------------------------------- Summary: Cleaning old log files created by Sifting appender child Key: LOGBACK-1432 URL: https://jira.qos.ch/browse/LOGBACK-1432 Project: logback Issue Type: Bug Environment: I have SiftingAppender which creates logs per each job run. I need to automatically clean log files which are 2 weeks old. I tried to use RollingAppender, but it does not work since each log file name has unique job run id. This is what I have tired so far: {code:java} <configuration> <!-- To see the errors generated by SiftingAppender--> <statusListener class="ch.qos.logback.core.status.OnConsoleStatusListener" /> <appender name="JOB_LOG" class="ch.qos.logback.classic.sift.SiftingAppender"> <!-- This is MDC value --> <!-- We will assign a value to 'jobRunId' via Java code --> <discriminator> <key>jobRunId</key> <defaultValue>null</defaultValue> </discriminator> <!-- This is filter to deny log events which mdc value for 'jobRunId' equals 'null'. --> <filter class="ch.qos.logback.core.filter.EvaluatorFilter"> <evaluator class="ch.qos.logback.classic.boolex.JaninoEventEvaluator"> <expression> mdc.get("jobRunId") == null </expression> </evaluator> <OnMismatch>NEUTRAL</OnMismatch> <OnMatch>DENY</OnMatch> </filter> <sift> <appender name="FILE-${jobRunId}" class="ch.qos.logback.core.rolling.RollingFileAppender"> <file>logs/jobs/${jobRunId}.log</file> <encoder> <pattern>%d{HH:mm:ss.SSS} [%level] [%logger{60}] - %msg%n</pattern> </encoder> <rollingPolicy class="ch.qos.logback.core.rolling.TimeBasedRollingPolicy"> <!-- Set to minutes for testing purposes. TODO: change to daily rollover. --> <fileNamePattern>logs/jobs/%d{yyyy-MM-dd_HH:mm:ss}.${jobRunId}.log</fileNamePattern> <!-- Set to 5 seconds for testing purposes. TODO: change to 14 days. --> <maxHistory>5</maxHistory> <cleanHistoryOnStart>true</cleanHistoryOnStart> </rollingPolicy> </appender> </sift> </appender> <root level="TRACE"> <appender-ref ref="JOB_LOG"/> </root> </configuration> {code}   Console log suggests that files have been archived. But clean on start does not delete them I would assume since each appender name is dynamic in my case: {code} 15:18:15,194 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.rolling.RollingFileAppender] 15:18:15,197 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [FILE-aFuq3Q8H96] 15:18:15,204 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Assuming default type [ch.qos.logback.classic.encoder.PatternLayoutEncoder] for [encoder] property 15:18:15,228 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - No compression will be used 15:18:15,230 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Will use the pattern logs/jobs/%d{yyyy-MM-dd_HH:mm:ss}.aFuq3Q8H96.log for the active file 15:18:15,234 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - The date pattern is 'yyyy-MM-dd_HH:mm:ss' from file name pattern 'logs/jobs/%d{yyyy-MM-dd_HH:mm:ss}.aFuq3Q8H96.log'. 15:18:15,234 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - Roll-over every second. 15:18:15,234 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - Setting initial period to Thu Oct 25 15:18:15 PDT 2018 15:18:15,235 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Cleaning on start up 15:18:15,235 |-INFO in c.q.l.core.rolling.helper.TimeBasedArchiveRemover - first clean up after appender initialization 15:18:15,235 |-INFO in c.q.l.core.rolling.helper.TimeBasedArchiveRemover - periodsElapsed = 336 15:18:15,257 |-INFO in ch.qos.logback.core.rolling.RollingFileAppender[FILE-aFuq3Q8H96] - Active log file name: /logs/jobs/aFuq3Q8H96.log 15:18:15,258 |-INFO in ch.qos.logback.core.rolling.RollingFileAppender[FILE-aFuq3Q8H96] - File property is set to [/logs/jobs/aFuq3Q8H96.log] 15:18:15.193 INFO c.l.t.logging.testing.LogbackTest - Hello, I am MDC 15:18:17.261 INFO c.l.t.logging.testing.LogbackTest - Hello, I am not MDC 15:18:17,262 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - About to instantiate appender of type [ch.qos.logback.core.rolling.RollingFileAppender] 15:18:17,262 |-INFO in ch.qos.logback.core.joran.action.AppenderAction - Naming appender as [FILE-CjA2HVpgTq] 15:18:17,262 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Assuming default type [ch.qos.logback.classic.encoder.PatternLayoutEncoder] for [encoder] property 15:18:17,264 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - No compression will be used 15:18:17,264 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Will use the pattern /logs/jobs/%d{yyyy-MM-dd_HH:mm:ss}.CjA2HVpgTq.log for the active file 15:18:17,265 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - The date pattern is 'yyyy-MM-dd_HH:mm:ss' from file name pattern '/logs/jobs/%d{yyyy-MM-dd_HH:mm:ss}.CjA2HVpgTq.log'. 15:18:17,265 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - Roll-over every second. 15:18:17,265 |-INFO in c.q.l.core.rolling.DefaultTimeBasedFileNamingAndTriggeringPolicy - Setting initial period to Thu Oct 25 15:18:17 PDT 2018 15:18:17,265 |-INFO in c.q.l.core.rolling.TimeBasedRollingPolicy - Cleaning on start up 15:18:17,265 |-INFO in c.q.l.core.rolling.helper.TimeBasedArchiveRemover - first clean up after appender initialization 15:18:17,265 |-INFO in c.q.l.core.rolling.helper.TimeBasedArchiveRemover - periodsElapsed = 336 15:18:17,277 |-INFO in ch.qos.logback.core.rolling.RollingFileAppender[FILE-CjA2HVpgTq] - Active log file name: /logs/jobs/CjA2HVpgTq.log 15:18:17,277 |-INFO in ch.qos.logback.core.rolling.RollingFileAppender[FILE-CjA2HVpgTq] - File property is set to [/logs/jobs/CjA2HVpgTq.log] 15:18:17.261 INFO c.l.t.logging.testing.LogbackTest - Hello, I am MDC 15:18:19.277 INFO c.l.t.logging.testing.LogbackTest - Hello, I am not MDC{code} Reporter: Masha Buka Assignee: Logback dev list -- This message was sent by Atlassian JIRA (v7.3.1#73012)
