Description

Hello Sir,

With log4j2 2.13.3 , Route appenders with context pattern checks for dynamic file writing are working fine. After 2.17.1 the functionality is broken.

I have upgraded to 2.17.1 and our java code, I am setting the ROUTINGKEY in threadcontext map. Also i set the system properties,  log4j2.enableJndiLookup, log4j2.enableJndiJms, and log4j2.enableJndiContextSelector to true for all said tags after 2.17.1 upgrade.

When I check output file, its not writing the logs to Route File what we specify but general RollingFile logger appenders are working fine. Please let me know if you have faced this issue or any mitigation plan? Please let me know if you want any logs and i will share those if there is any specific procedure given. 

 

Calling the below Route from Async logging.

here my example xml used the same as given in log4j2 documentaion.

<Route key="$${ctx:ROUTINGKEY}">
<RollingFile name="Rolling-default" fileName="logs/default.log"
filePattern="./logs/${date:yyyy-MM}/default-%d{yyyy-MM-dd}-%i.log.gz">
<PatternLayout>
<pattern>%d{ISO8601} [%t] %p %c{3} - %m%n</pattern>
</PatternLayout>
<Policies>
<TimeBasedTriggeringPolicy interval="6" modulate="true" />
<SizeBasedTriggeringPolicy size="10 MB" />
</Policies>
</RollingFile>
</Route>

<Route>
<RollingFile name="Rolling-${ctx:ROUTINGKEY}" fileName="logs/other-${ctx:ROUTINGKEY}.log"
filePattern="./logs/${date:yyyy-MM}/${ctx:ROUTINGKEY}other%d{yyyy-MM-dd}-%i.log.gz">
<PatternLayout>
<pattern>%d{ISO8601} [%t] %p %c{3} - %m%n</pattern>
</PatternLayout>
<Policies>
<TimeBasedTriggeringPolicy interval="6" modulate="true" />
<SizeBasedTriggeringPolicy size="10 MB" />
</Policies>
</RollingFile>
</Route>
</Routes>
</Routing>
