java - Logback SyslogAppender 堆栈跟踪日志记录前缀

Question

我们最近从 Log4J 切换到 Logback。除了 SyslogAppender 中的堆栈跟踪外，日志记录似乎运行良好。它们就像剩余的日志消息一样带有前缀。

有什么方法可以禁用此前缀并确保它们将像在 Log4J SyslogAppender 中一样打印出来吗？提前致谢。

SyslogAppender 的当前 logback.xml:

  <appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender">
    <facility>local2</facility>
    <syslogHost>localhost</syslogHost>
    <suffixPattern>%d{yyyy-MM-dd'T'HH:mm:ss.SSSZ} %t %c %p: %m component=webapp request_id=%X{requestId} userId=%X{userId} projectId=%X{projectId} nodeId=%X{nodeId} %X%n</suffixPattern>
  </appender>

Answer 1

您可以通过将 throwableExcluded 参数设置为 true 并在后缀模式中指定异常来解决此问题。

<appender name="SYSLOG" class="ch.qos.logback.classic.net.SyslogAppender">
    <syslogHost>localhost</syslogHost>
    <facility>LOCAL7</facility>
    <throwableExcluded>true</throwableExcluded>
    <suffixPattern>%d{ISO8601} %p %t %c{0}.%M - %m%n%xException</suffixPattern>
</appender>

根据您使用的系统日志服务器，您可能需要关闭控制字符转义，以便正确呈现文本。例如$EscapeControlCharactersOnReceive off 用于 rsyslog v5
