我一直在记录太多信息（目前不需要）syslog，不是每天或每小时...而是即时的。如果我想在我的记录中查看某些内容，syslog我就是无法做到，因为网络日志一直在干扰。
那么，我如何才能将网络日志重定向到另一个文件和/或停止记录它？

答案1
从您的输出来看，来自网络芯片的调试日志似乎太嘈杂了。不幸的是，除非该模块有一些选项（在 Google 上快速查看显示唯一的选项是在编译时），否则我认为您将无法做您想做的事情。
检查/etc/rsyslog.d/50-default.conf并检查第一行是否有类似内容 *.*;auth,authpriv.none
将其更改为
*.err;auth,authpriv.none
行尾会有一个文件路径。但是，这会停止所有日志记录。您可能不想这样做。
当你需要读取该文件时，你可以这样做
tail /var/log/syslog -n 1000 | grep -v "RT35xx|rt28xx
使用 -v 将仅显示不匹配的行，并且参数是正则表达式，因此您可以得到更复杂的结果。但是看起来该驱动程序很邪恶，开发人员需要严厉惩罚，因为使其过于冗长。
总结一下：
首先尝试降低驱动程序的详细程度。这将是您的最佳选择。
接下来创建某种 grep 语句来过滤掉您不想要的行。
最后，如果其他方法都不起作用，或者您不在乎，请关闭日志记录。
如果您决定关闭日志记录，请注意，您可以更有选择性地关闭内核日志记录。但我并不推荐这样做。
