○ Use the --follow option and watch dmesg messages in real-time. dmesg的时间 首先dmesg是没有日期或者标准的时间的,但是dmesg日志存在时间戳,如下所示: image.png Understanding dmesg timestamp is pretty simple: it is time in seconds since the kernel started. So, having time of startup ( uptime...

/sys/module/printk/parameters/time这个可读写参数控制着内联模块 printk 在打印内核消息时是否加上时间前缀;所有内联模块的参数也可以由<module_name>.<param_name>=<value>的形式写在内核启动参数上 如启动内核时加上参数printk.time=1与 向/sys/module/printk/parameters/time写入1的效果相同;没有非0属性参数的...

with large uptime though. Turns out that kernel timestamps in dmesg are derived from an uptime value kept by individual CPUs. Over time this gets out of sync with the real time clock. As a result, the most accurate conversion for recent ...
Some distro allows command ‘tail -f /var/log/dmesg’ as well for real time dmesg monitoring. [root@tecmint.com log]# watch "dmesg | tail -20" Conclusion: The dmesg command is useful as dmesg records all the system changes done or occur in real time. As always you canman dmesgto ge...
