Marker filter not working

[eddyZ]

Hi,

I have two different appenders that filter based on markers.
Both should only append logs with my 'AUDIT' marker. Although if the filter is exactly the same in both appenders, it works for the console appender, but not for the Kafka appender. In Kafka, no messages appear (but if I remove the filter, they show up).

<appender name="fast-kafka-appender" class="com.github.danielwegener.logback.kafka.KafkaAppender">
    <filter class="ch.qos.logback.core.filter.EvaluatorFilter">
        <evaluator class="ch.qos.logback.classic.boolex.OnMarkerEvaluator">
            <marker>AUDIT</marker>
        </evaluator>
        <onMismatch>DENY</onMismatch>
        <onMatch>NEUTRAL</onMatch>
    </filter>

    <encoder class="ch.qos.logback.classic.encoder.PatternLayoutEncoder">
        <pattern>AUDITING: %d{HH:mm:ss.SSS} [%thread] %-5level %marker %logger{36} - %msg%n</pattern>
    </encoder>

    <topic>audit-logs</topic>
    <keyingStrategy class="com.github.danielwegener.logback.kafka.keying.NoKeyKeyingStrategy" />
    <deliveryStrategy class="com.github.danielwegener.logback.kafka.delivery.AsynchronousDeliveryStrategy" />

    <producerConfig>bootstrap.servers=localhost:9092</producerConfig>
    <producerConfig>acks=0</producerConfig>
    <producerConfig>linger.ms=100</producerConfig>
    <producerConfig>max.block.ms=2</producerConfig>
    <producerConfig>client.id=${HOSTNAME}-${CONTEXT_NAME}-logback-relaxed</producerConfig>

</appender>
<appender name="AUDIT_LOG" class="ch.qos.logback.core.ConsoleAppender">
    <!-- the filter element -->
    <filter class="ch.qos.logback.core.filter.EvaluatorFilter">
        <evaluator class="ch.qos.logback.classic.boolex.OnMarkerEvaluator">
            <marker>AUDIT</marker>
        </evaluator>
        <onMismatch>DENY</onMismatch>
        <onMatch>NEUTRAL</onMatch>
    </filter>
    <encoder>
        <pattern>
            %green(eddas log: %d{ISO8601}) %highlight(%-5level) [%blue(%t)] %yellow(%logger{36}): %magenta(%msg%n%throwable)
        </pattern>
    </encoder>
</appender>

I managed also to exclude all my AUDIT logs like that:
<filter class="ch.qos.logback.core.filter.EvaluatorFilter"> <evaluator class="ch.qos.logback.classic.boolex.OnMarkerEvaluator"> <marker>AUDIT</marker> </evaluator> <onMatch>DENY</onMatch> </filter>
This works, but it is the opposite of what I need ;)

Can you tell my why my filter is not working?
