While I work on figuring out how to get a newer version of log4j2 installed I'm
wondering whether there is some additional investigation I can do with the
version I have. For instance, I was hoping with the level of logging I have
enabled, that log4j would be indicating some issue it had with the custom
level. However, I don't see such an issue. The only thing I see is an issue
with the custom level, which I'm guessing is when I'm using it in the filter.
I've attached the warning in the log below.
Is there some additional logging I can turn on such that log4j will produce
more info which might indicate why my custom levels aren't working? Here is my
current log4j2 configuration.
log4j2.xml:
<?xml version="1.0" encoding="UTF-8"?>
<Configuration status="trace" verbose="true">
<CustomLevels>
<CustomLevel name="INFOM1" intLevel="399"/>
<CustomLevel name="INFOP1" intLevel="401"/>
</CustomLevels>
<Appenders>
<File name="info" fileName="info.log">
<PatternLayout>
<Pattern>%d %p %c{1.} [%t] %m%n</Pattern>
</PatternLayout>
<Filters>
<ThresholdFilter level="INFOM1" onMatch="DENY" onMismatch="NEUTRAL"/>
<ThresholdFilter level="INFO" onMatch="ACCEPT" onMismatch="DENY"/>
</Filters>
</File>
</Appenders>
<Loggers>
<Logger name="HelloWorld" level="ALL">
<AppenderRef ref="info"/>
</Logger>
<Root>
</Root>
</Loggers>
</Configuration>
