如何监控和压力测试超频的 Ubuntu 系统？

Question

我推荐stress-ng（因为我将它编写用于压力测试系统），它内置了广泛的压力测试。矩阵压力器是一个很好的入门工具，因为它可以测试CPU浮点、缓存和内存，例如：

stress-ng --matrix 0 -t 60s --tz
stress-ng: info:  [10514] dispatching hogs: 4 matrix
stress-ng: info:  [10514] cache allocate: default cache size: 3072K
stress-ng: info:  [10514] successful run completed in 60.00s (1 min, 0.00 secs)
stress-ng: info:  [10514] matrix:
stress-ng: info:  [10514]               acpitz   78.00 °C
stress-ng: info:  [10514]         x86_pkg_temp   78.25 °C

上述操作在所有 CPU 上运行矩阵压力器 60 秒，并转储 ACPI 热区和 CPU 封装温度的热区温度。

CPU 压力器还包含多种压力方法，例如，要在 2 个 CPU 上执行 30 秒的长时间双浮点运算来对 CPU 施加压力，请使用以下命令：

stress-ng --cpu 2 --cpu-method longdouble  -t 30s --tz --metrics-brief
stress-ng: info:  [10572] dispatching hogs: 2 cpu
stress-ng: info:  [10572] cache allocate: default cache size: 3072K
stress-ng: info:  [10572] successful run completed in 30.00s
stress-ng: info:  [10572] stressor       bogo ops real time  usr time  sys time   bogo ops/s   bogo ops/s
stress-ng: info:  [10572]                           (secs)    (secs)    (secs)   (real time) (usr+sys time)
stress-ng: info:  [10572] cpu               71482     30.00     59.96      0.00      2382.65      1192.16
stress-ng: info:  [10572] cpu:
stress-ng: info:  [10572]               acpitz   76.00 °C
stress-ng: info:  [10572]         x86_pkg_temp   76.50 °C

要查看所有 CPU 压力源方法，请使用：

stress-ng --cpu-method which
