Integrating logstash (elk) with mulesoft

Is there a way we could feed the mule cloudhub logs to logstash?

I am able to configure agents as in this link

https://docs.mulesoft.com/cloudhub/sending-data-from-arm-to-external-monitoring-software

But I am unable to configure logstash.

You could use log4j socket appender, if cloudhub allows connecting to outside server. You could configure logstash to listen to tcp for logs, you could refer to this, https://www.elastic.co/guide/en/logstash/current/plugins-inputs-tcp.html. Here is an example of tcp input for logstash(https://gist.github.com/jgoodall/6323951), make sure you set the correct format for mule because there would be a problem with multiline data. Also configure your app, for older version of mule, you could add log4j.xml

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">

<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
  <appender name="console" class="org.apache.log4j.ConsoleAppender">
    <param name="Target" value="System.out" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d{dd-MM-yyyy HH:mm:ss} %-5p [%t] [%c] - %m%n" />
    </layout>
    <filter class="org.apache.log4j.varia.LevelRangeFilter">
        <param name="LevelMin" value="ERROR" />
        <param name="LevelMax" value="FATAL" />
        <param name="AcceptOnMatch" value="true" />
    </filter>
</appender>
<appender name="socket" class="org.apache.log4j.net.SocketAppender">
    <param name="Threshold" value="INFO" />
    <param name="application" value="AppName" />
    <param name="Port" value="4560" />
    <param name="RemoteHost" value="remotehost.com" />
    <param name="ReconnectionDelay" value="60000" />
    <layout class="org.apache.log4j.PatternLayout">
        <param name="ConversionPattern" value="%d{dd-MM-yyyy HH:mm:ss} %-5p [%t] [%c] - %m%n" />
    </layout>

</appender>

 <appender name="asyncConsole" class="org.apache.log4j.AsyncAppender">
    <param name="BufferSize" value="200"/>
    <appender-ref ref="console"/>
</appender>

<appender name="asyncFile" class="org.apache.log4j.AsyncAppender">
    <param name="BufferSize" value="200"/>
    <appender-ref ref="file"/>
</appender>

<appender name="asyncSocket" class="org.apache.log4j.AsyncAppender">
    <param name="BufferSize" value="200"/>
    <appender-ref ref="socket"/>
</appender>

<logger name="Tracking"  additivity="false">
    <level value="warn" />
    <appender-ref ref="asyncConsole" />
    <appender-ref ref="asyncFile" />
    <appender-ref ref="asyncSocket" />
</logger>

<logger name="com.mulesoft.module.datamapper"  additivity="false">
    <level value="warn" />
    <appender-ref ref="asyncConsole" />
    <appender-ref ref="asyncFile" />
    <appender-ref ref="asyncSocket" />
</logger>

<logger name="org.mule.api.processor.LoggerMessageProcessor" additivity="false">
    <level value="info" />
    <appender-ref ref="asyncConsole" />
    <appender-ref ref="asyncFile" />
    <appender-ref ref="asyncSocket" />
</logger>
<root>
    <priority value="info" />
    <appender-ref ref="asyncConsole" />
    <appender-ref ref="asyncFile" />
    <appender-ref ref="asyncSocket" />
</root>

Notice the socket appender, from there you could configure the host and port of the logstash instance. For newer version of mule, there is a log4j2.xml, the configuration for the socket appender is similar.
