net.logstash.logback.appender.LogstashUdpSocketAppender fails if host is NULL

Open mmuruev opened this issue 1 year ago • 0 comments

If host value is null, and appeder in use with async appended it causes an exception. To Reproduce Steps to reproduce the behavior:

<configuration debug="true">
    <appender name="CONSOLE" class="ch.qos.logback.core.ConsoleAppender">
        <encoder>
            <pattern>
                %d{yyyy-MM-dd HH:mm:ss.SSS} %-5level[%.15thread] %level %logger{1}@%line - %msg%n
            </pattern>
        </encoder>
    </appender>

    <appender name="LOGSTASH_UDP" class="net.logstash.logback.appender.LogstashUdpSocketAppender">
        <host>${LOGSTASH_HOST:-localhost}</host>
        <port>5000</port>
        <encoder class="net.logstash.logback.encoder.LogstashEncoder"/>
        <layout class="net.logstash.logback.layout.LogstashLayout">
            <customFields>{"app":"service","namespace":"${MY_POD_NAMESPACE}"}</customFields>
        </layout>
    </appender>

    <appender name="ASYNC_LOGSTASH" class="net.logstash.logback.appender.LoggingEventAsyncDisruptorAppender">
        <appender-ref ref="LOGSTASH_UDP"/>
    </appender>

    <springProfile name="local,test">
        <root level="info">
            <appender-ref ref="CONSOLE"/>
        </root>
    </springProfile>

    <springProfile name="dev">
        <root level="info">
            <appender-ref ref="ASYNC_LOGSTASH"/>
            <appender-ref ref="CONSOLE"/>
        </root>
    </springProfile>

    <springProfile name="prod">
        <root level="info">
            <appender-ref ref="ASYNC_LOGSTASH"/>
        </root>
    </springProfile>

    <shutdownHook class="ch.qos.logback.core.hook.DefaultShutdownHook"/>

</configuration>

result for localhost (no LOGSTASH_HOST value, and never required)

  • logstash-logback-encoder version net.logstash.logback:logstash-logback-encoder:7.4

As solution for now

But this is not 100% correct I belive is just run it against localhost. Better never start it. And if I remove async appended everything is fine.
