本文详细介绍了Linux系统监控的一些关键工具和文件，如`uptime`用于查看系统运行时间和负载平均值，`/proc`目录下如`loadavg`和`stat`提供CPU和系统状态信息，`vmstat`展示内存、交换、IO和CPU活动，以及`/sys/devices/system/cpu`揭示CPU调度详情。这些工具对于理解和优化Linux系统的性能至关重要。

uptime

Tell the current time, how long the system has been running, the number of users, and the system load averages for the past 1, 5 and 15 minutes.

Usage:
uptime [options]

Options:
-p, --pretty show uptime in pretty format
-h, --help display this help and exit
-s, --since system up since
-V, --version output version information and exit

$ uptime
 09:34:30 up 12 min,  0 users,  load average: 6.78, 6.98, 4.92

$ uptime -s
2021-01-28 09:22:10

/proc/loadavg

The first three columns measure CPU and IO utilization of the last one, five, and 10 minute periods. The fourth column shows the number of currently running processes and the total number of processes. The last column displays the last process ID used.

$ cat /proc/loadavg
6.64 7.00 5.63 4/3687 8040

/proc/stat

# cat /proc/stat
