Benutzerdefinierte Appender in Karaf Decanter Funktioniert nicht

Question

Ich versuche, einen benutzerdefinierten Appender mit Dekanter wie erwähnt here zu erstellen. Mein Ziel ist es, alle von Karaf-Bundles ausgegebenen Logs zu hören und in der Konsole anzuzeigen. Ich verwende Karaf 3.0.4 unter Apache Servicemix 6.1.0

Ich habe Decanter Feature-Repository in Karaf & dann Collector-Log und Appender-Log wie in der Dekanter-Dokumentation erwähnt installiert.

Meine benutzerdefinierte appender sieht aus wie folgt: -

package com.jabong.karaf.decanter.appender.elklog; 

import org.osgi.service.event.Event; 
import org.osgi.service.event.EventHandler; 

public class ELKLogAppender implements EventHandler { 
    @Override 
    public void handleEvent(Event event) { 
    for (String name : event.getPropertyNames()) { 
     System.out.println("Custom Debraj" + name + ":" + event.getProperty(name)); 
    } 
    } 
} 

Mein Activator sieht aus wie folgt: -

package com.jabong.karaf.decanter.appender.elklog; 

import java.util.Dictionary; 
import java.util.Hashtable; 

import org.osgi.framework.BundleActivator; 
import org.osgi.framework.BundleContext; 
import org.osgi.framework.ServiceRegistration; 
import org.osgi.service.event.EventConstants; 
import org.osgi.service.event.EventHandler; 

public class Activator implements BundleActivator { 
    private ServiceRegistration registration; 

    @Override 
    public void start(BundleContext bundleContext) { 
    ELKLogAppender appender = new ELKLogAppender(); 
    Dictionary<String, String> properties = new Hashtable<>(); 
    properties.put(EventConstants.EVENT_TOPIC, "decanter/collect/*"); 
    registration = bundleContext.registerService(EventHandler.class, appender, properties); 
    } 

    @Override 
    public void stop(BundleContext bundleContext) { 
    if (registration != null) { 
     registration.unregister(); 
    } 
    } 
} 

Meine pom.xml wie unten aussieht: -

I konnte das Paket korrekt in Karaf installieren, indem es in den Ordner deploy gelegt wurde.

Mein org.ops4j.pax.logging.cfg in Karaf sieht aus wie folgt: -

# Root logger 
log4j.rootLogger=INFO, out, osgi:VmLogAppender 
log4j.throwableRenderer=org.apache.log4j.OsgiThrowableRenderer 

# To avoid flooding the log when using DEBUG level on an ssh connection and doing log:tail

log4j.appender.sift.appender.append=true 

Aber ich bin keine Nachricht auf der Konsole zu sehen. Auch wenn ich in data/servicemix.log

Answer 1

In etc/org.ops4j.pax.logging.cfg viele Protokolle bin zu sehen, zu

Ändern

log4j.rootLogger=INFO, out, osgi:* 

von

log4j.rootLogger=INFO, out, osgi:VmLogAppender 

löste das Problem .
