我的logback syslog追加程序出了什么问题?

问题描述

我正在尝试使logback syslog附加程序正常工作，并且我肯定配置有误.我已经创建了一个小型示例项目，我认为它应该记录到syslog中，但事实并非如此. /p>

我确定我缺少一些愚蠢的东西.这是来自 logback.xml 的附加程序:

<appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender">
    <syslogHost>localhost</syslogHost>
    <facility>USER</facility>
    <suffixPattern>[%thread] %logger %msg</suffixPattern>
</appender>

我尝试过显式添加端口(514)，这并不令人高兴.在我尝试过的两个系统上，我都已验证syslog是否使用logger "test message"接收输入，然后尾随/var/log/messages或/var/log/system.log.

为了将logback/slf4j记录到syslog，我需要更改什么?

解决方案

您的代码没有任何问题，问题在于系统配置.使用您提供的测试项目，我能够使syslog附加程序正常工作(Ubuntu 14.10).

以下是一些步骤:

• 编辑/etc/syslog.conf并确保已启用网络系统日志:

# provides UDP syslog reception
$ModLoad imudp
$UDPServerRun 514

# provides TCP syslog reception
# note that logback seems to use UDP, so this isn't strictly necessary.
$ModLoad imtcp
$InputTCPServerRun 514

• 如果更改配置，请重新启动rsyslog(service rsyslog restart)(重新加载无效)
• 检查syslog是否正在使用lsof -i | grep syslog
进行监听

结果:

I'm trying to get a logback syslog appender working, and I've definitely got something misconfigured. I've created a small sample project which I think should log to syslog, yet it doesn't.

I'm sure I'm missing something stupid. Here's the appender from logback.xml:

<appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender">
    <syslogHost>localhost</syslogHost>
    <facility>USER</facility>
    <suffixPattern>[%thread] %logger %msg</suffixPattern>
</appender>

I've tried adding the port (514) explicitly, and, no joy. on both systems I've tried this on, I've verified syslog is receiving input using logger "test message" and then tailing either /var/log/messages or /var/log/system.log.

What do I need to change in order to get logback/slf4j logging to syslog?

解决方案

Nothing is wrong with your code, the problem is the system config.Using your provided test project, I was able to make the syslog appender work (Ubuntu 14.10).

Here are some steps:

• edit /etc/syslog.conf and ensure you have network syslog enabled:

# provides UDP syslog reception
$ModLoad imudp
$UDPServerRun 514

# provides TCP syslog reception
# note that logback seems to use UDP, so this isn't strictly necessary.
$ModLoad imtcp
$InputTCPServerRun 514

• restart rsyslog (service rsyslog restart) if you change the config (reload doesn't work)
• check that syslog is listening with lsof -i | grep syslog
