问题描述

我需要将我的Java应用程序写入记录到GrayLog2服务器. 该应用程序使用Log4J配置. 我试图将记录写入到GrayLog2服务器上的几件事，我工作的东西是直接向服务器发送测试消息，如所示此处(第一个示例).

然而，当我编写一个appender并将其附加到根记录器上时，我总是会收到此错误消息，这是第一次要发射日志事件:

log4j:错误无法发送gelf消息

我试图工作的appender:

<appender name="graylog2" class="org.graylog2.log.GelfAppender">
    <param name="graylogHost" value="127.0.0.1"/>
    <param name="originHost" value="my.machine.example.com"/>
    <param name="extractStacktrace" value="true"/>
    <param name="addExtendedInformation" value="true"/>
    <param name="facility" value="gelf-java"/>
    <param name="Threshold" value="INFO"/>
    <param name="additionalFields" value="{'environment': 'DEV', 'application': 'MyAPP'}"/>
</appender>

有人知道如何运行这个吗?
任何帮助都非常感谢！

通过Java代码，我附加了GelfAppender，甚至我遇到的错误与:

log4j:ERROR Could not send GELF message

我发现错误的原因是我没有调用

activateOptions();

此功能将设置我们使用

进行INTIAL的GELFSENER

private GelfSender gelfSender;

一旦将gelfSender设置为总结，可以将消息发送到GELF.

这是我用来获得GelfAppender

的代码

GelfAppender appender = new GelfAppender();
    appender.setName("GrayLogAppender");
    appender.setGraylogHost("localhost");
    appender.setGraylogPort(12201);
    appender.setFacility("gelf-java");
    appender.setOriginHost("localhost");
    appender.setLayout(lyt);
    appender.setExtractStacktrace(true);
    appender.setAddExtendedInformation(true);
    appender.setAdditionalFields("{'environment': 'DEV', 'application':'MyAPP'}");
    appender.activateOptions();

查看catalina.out(通常位于tomcat/logs下)查看与GELF

有关的错误消息

问题描述

I need to get my Java application writing logging to a Graylog2 server. The application uses a log4j configuration. Several things I have tried to get the logging writing to the Graylog2 server, the things I got working was sending a test message directly to the server, as shown here (first example).

Yet, when I write an appender and attach it to the root logger, I always get this error message the first time a log event is to be fired:

log4j:ERROR Could not send GELF message

Nothing then happens on the Graylog2 server side.

The appender I try to get working:

<appender name="graylog2" class="org.graylog2.log.GelfAppender">
    <param name="graylogHost" value="127.0.0.1"/>
    <param name="originHost" value="my.machine.example.com"/>
    <param name="extractStacktrace" value="true"/>
    <param name="addExtendedInformation" value="true"/>
    <param name="facility" value="gelf-java"/>
    <param name="Threshold" value="INFO"/>
    <param name="additionalFields" value="{'environment': 'DEV', 'application': 'MyAPP'}"/>
</appender>

Does anyone have an idea how to get this running?
Any help is highly appreciated!

Through java code I appended the GelfAppender and even I was getting the same error as:

log4j:ERROR Could not send GELF message

The reason I found for the error is that I was not calling the

activateOptions();

This function will set the gelfSender which we had intialized using

private GelfSender gelfSender;

Once the gelfSender is set to sumthing the message can be sent to GELF.

here is the code how I used to get the GelfAppender

GelfAppender appender = new GelfAppender();
    appender.setName("GrayLogAppender");
    appender.setGraylogHost("localhost");
    appender.setGraylogPort(12201);
    appender.setFacility("gelf-java");
    appender.setOriginHost("localhost");
    appender.setLayout(lyt);
    appender.setExtractStacktrace(true);
    appender.setAddExtendedInformation(true);
    appender.setAdditionalFields("{'environment': 'DEV', 'application':'MyAPP'}");
    appender.activateOptions();

Look in catalina.out (usually located under tomcat/logs) for error messages related to Gelf
