本文介绍了Log4j和syslogappender的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我有一个使用log4j SyslogAppender（facility = USER）的java应用程序，我可以看到在端口514上使用tcpdump，我的应用程序正在发送预期的日志消息作为数据报，netstat也告诉我syslogd（red hat）正在运行，在0.0.0.0:514上收听，但我没有在/ var / log / messages中看到任何日志记录。

I have a java application using log4j SyslogAppender (facility=USER) and I can see using tcpdump on port 514 that my application is sending intended log message as a datagram and also netstat shows me that syslogd (red hat) is running and listening on 0.0.0.0:514 but I do not see any logging happening in /var/log/messages.

在我的syslog.conf中，我有

In my syslog.conf, I have

*.info         /var/log/messages

我对SyslogAppender的转换模式是

My conversion pattern for SyslogAppender is

%d{MMM dd HH:mm:ss} %F %L %5p [%t] %m %n"

我无法理解为什么它没有记录或我应该在哪里找到什么是失败的。我没有足够的机器上的权限，用于启动/停止syslogd或手动运行以启用详细的调试日志。

I am clueless as why it is failing to log or where exactly should I look for to see what is failing. And I don't have enough permissions on the machine to start/stop syslogd or run manually to have verbose debug logs enabled.

有关如何继续的任何指示？

Any pointers as how I proceed?

编辑：

下面的Appender

The Appender below

private void initSyslog() {
    SyslogAppender syslogAppender = new SyslogAppender();
    syslogAppender.setName("syslog");
    syslogAppender.setLayout(new PatternLayout("%d{MMM dd HH:mm:ss} %F %L %5p [%t] %m %n"));
    syslogAppender.setFacility("USER");
    syslogAppender.setFacilityPrinting(true);
    syslogAppender.setSyslogHost("localhost");
    syslogAppender.activateOptions();
    Logger.getRootLogger().addAppender(syslogAppender);
    Logger.getRootLogger.info("Syslogdone");
}
