如何在Log4j写入Linux syslog的消息中更改localhost.localdomain [英] How can I change localhost.localdomain in the messages written by Log4j to the Linux syslog

问题描述

我正在使用Log4j及其SyslogAppender将消息写入Linux syslog.输出的消息如下所示:

I'm writing messages to the Linux syslog using Log4j and its SyslogAppender. The outputted messages look like this:

Oct 12 09:06:03 localhost.localdomain 3364 [Thread-5] INFO TEST MESSAGE MyApplicationLogger - This is my message

我想将localhost.localdomain替​​换为运行该应用程序的服务器的名称，但似乎无法弄清楚该怎么做.如果有用的话，这是我的配置文件:

I would like to replace localhost.localdomain with the name of the server running the application but can't seem to figure out how. Here's my configuration file, in case it's useful:

log4j.logger.MyApplicationLogger=INFO, SyslogAppender
log4j.appender.SyslogAppender=org.apache.log4j.net.SyslogAppender
log4j.appender.SyslogAppender.syslogHost=localhost
log4j.appender.SyslogAppender.Facility=USER
log4j.appender.SyslogAppender.layout=org.apache.log4j.PatternLayout
log4j.appender.SyslogAppender.layout.ConversionPattern= %-4r [%t] %-5p %c %x - %m%n
log4j.appender.SyslogAppender.source=My Application

编辑:在服务器上配置了计算机名称，并且hostname命令返回以下内容:

Edit: the computer name is configured on the server and the hostname command returns the following:

$ hostname
server12

但是我确实注意到hosts文件的第一行是

I do notice however that the first line of the hosts file is

127.0.0.1   localhost.localdomain localhost

但是我仍然不愿意更改它.

However I'm hesitant to change this.

推荐答案

我想出了解决方法，所以如果其他人遇到相同的问题，我也最好将解决方案留在这里.

I figured out how to fix it, so I might as well leave the solution here in case other people face the same problem.

在属性文件中，输入以下内容:

In the properties file, put this:

log4j.appender.SyslogAppender.syslogHost=server12

不确定为什么可以使用，但是使用服务器名称代替localhost可以解决我的问题.

Not sure why it works, but using the server name instead of localhost worked for me.
