Question

我正在尝试使用Decanter创建自定义appender，如上所述here。我的目标是监听karaf捆绑包输出的所有日志并将其显示在控制台中。我在Apache Servicemix 6.1.0下使用Karaf 3.0.4

我在Karaf＆amp; amp;添加了Decanter功能库。然后按照Decanter文档中的说明安装了collector-log和appender-log。

我的自定义appender如下所示： -

Activator

我的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(); } } }如下所示： -

我可以将它放在332 | Active | 80 | 0.0.1 | basecomponent 333 | Active | 80 | 1.0.1 | Apache Karaf :: Decanter :: API 334 | Active | 80 | 1.0.1 | Apache Karaf :: Decanter :: Collector :: Log 337 | Active | 80 | 1.0.1 | Apache Karaf :: Decanter :: Appender :: Log 339 | Active | 80 | 0.0.1 | Apache Karaf :: Decanter :: Appender :: ELKLog 340 | Active | 80 | 2.4.0 | Commons IO 341 | Active | 80 | 1.0.1 | Apache Karaf :: Decanter :: Collector :: File文件夹中，在Karaf中正确安装捆绑包。

org.ops4j.pax.logging.cfg

我在卡拉夫的# 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.logger.org.apache.sshd.server.channel.ChannelSession = INFO # CONSOLE appender not used by default log4j.appender.stdout=org.apache.log4j.ConsoleAppender log4j.appender.stdout.layout=org.apache.log4j.PatternLayout log4j.appender.stdout.layout.ConversionPattern=%d{ISO8601} | %-5.5p | %-16.16t | %-32.32c{1} | %X{bundle.id} - %X{bundle.name} - %X{bundle.version} | %X | %m%n # File appender log4j.appender.out=org.apache.log4j.RollingFileAppender log4j.appender.out.layout=org.apache.log4j.PatternLayout log4j.appender.out.layout.ConversionPattern=%d{ISO8601} | %-5.5p | %-16.16t | %-32.32c{1} | %X{bundle.id} - %X{bundle.name} - %X{bundle.version} | %X | %m%n log4j.appender.out.file=${karaf.data}/log/servicemix.log log4j.appender.out.append=true log4j.appender.out.maxFileSize=100MB log4j.appender.out.maxBackupIndex=10 # Sift appender log4j.appender.sift=org.apache.log4j.sift.MDCSiftingAppender log4j.appender.sift.key=bundle.name log4j.appender.sift.default=servicemix log4j.appender.sift.appender=org.apache.log4j.FileAppender log4j.appender.sift.appender.layout=org.apache.log4j.PatternLayout log4j.appender.sift.appender.layout.ConversionPattern=%d{ISO8601} | %-5.5p | %-16.16t | %-32.32c{1} | %X | %m%n log4j.appender.sift.appender.file=${karaf.data}/log/$\\{bundle.name\\}.log log4j.appender.sift.appender.append=true如下所示： -

data/servicemix.log

但我在控制台上没有看到任何消息。即使我在subs(replacement, simultaneous=True)

中看到很多日志

Answer 1

在etc / org.ops4j.pax.logging.cfg中，更改为

log4j.rootLogger=INFO, out, osgi:*

这

log4j.rootLogger=INFO, out, osgi:VmLogAppender

解决了这个问题。

自定义Appender在Karaf Decanter不工作
