Linux云计算进阶-10条指令在1分钟内排查出服务器问题之dmesg篇

dmesg 可以查看Linux 内核引导相关的所有信息

dmesg’命令设备故障的诊断是非常重要的。在‘dmesg’命令的帮助下进行硬件的连接或断开连接操作时，我们可以看到硬件的检测或者断开连接的信息。‘dmesg’命令在多数基于Linux和Unix的操作系统中都可以使用。

列出加载到内核中的所有驱动

我们可以使用如‘more’。 ‘tail’, ‘less ’或者‘grep’文字处理工具来处理‘dmesg’命令的输出。由于dmesg日志的输出不适合在一页中完全显示，因此我们使用管道（pipe）将其输出送到more或者less命令单页显示。

显示时间戳

使用dmesg -T可以显示对应事件的时间戳。

人性化显示

使用dmesg -H指令，人性化显示信息，如下图所示。

过滤系统初始化时的错误信息

服务器在初始化启动和启动后运行的一段时间内，如果有对应的报错，会将报错信息进行收集，然后通过dmesg指令可以查看，如下。

[root@hanyw-Bash-Python ~]# dmesg -T |grep  -i 'error\|fail\|warn'
