安装 powerstat
如果存储库中有 powerstat可用，那么我们可以使用
# yum install powerstat
或者我们可以随时根据环境下载此工具并在本地安装。
# rpm -Uvh /tmp/powerstat-0.02.17-10.1.x86_64.rpm warning: /tmp/powerstat-0.02.17-10.1.x86_64.rpm: Header V3 DSA/SHA1 Signature, key ID ee454f98: NOKEY Preparing... ################################# [100%] Updating/installing... 1:powerstat-0.02.17-10.1 ################################# [100%]
重要说明：当 CPU/内存/磁盘 IO 消耗进程从空闲状态转换为多次运行时，功耗将主要波动。
基于此转换所需的时间，例如：从更深的 CPU c 状态到 C) 需要时间并影响电源使用。
如果一个进程一直处于运行状态，那么功耗将是恒定的。
情况 1：系统空闲
在开始之前让我们测量一下系统完全空闲时的电量使用情况
在下面的示例中，我每秒采集 60 个示例。
# powerstat -R -c -z Running for 60.0 seconds (60 samples at 1.0 second intervals). Power measurements will start in 0 seconds time.

因此，在我的刀片机上，系统空闲时的平均功耗约为 30W。
正如我们所看到的，当系统处于空闲状态时，CPU 会进入更深的睡眠状态，从而节省电量。
情况 2：当系统处于负载状态时
为了重现这个环境，我将使用“压力”工具在我的 CPU、内存和磁盘上施加一些负载。
我将其中一个终端中运行以下命令以在节点上加载一些负载
# stress -c 18 -i 13 -m 3 stress: info: [5200] dispatching hogs: 18 cpu, 13 io, 3 vm, 0 hdd
接下来检查电源使用情况

如我们所见，CPU 始终处于运行状态“C0”，功耗约为 137W
具有配置文件延迟性能
在这个经过调整的配置文件中，我们将 force_latency 值设置为“1”，因此即使系统空闲，CPU c-state 也不会低于 C1.
因此，由于系统从不真正休眠，因此功耗总是比较高。
情况 1：系统空闲
在开始之前，让我们测量一下系统完全空闲时的电量使用情况

正如预期的那样，此处系统空闲时的功耗约为 72W，而对于吞吐量性能而言，功耗约为 30W。
此外，如果我们注意到 CPU c-state 始终保持在 C1-HSW，而对于吞吐量性能，当系统空闲时，活动 CPU c-state 为 C6-HSW。
情况 2：当系统处于负载状态时
为了重现这个环境，我将使用“压力”工具在我的 CPU、内存和磁盘上施加一些负载。
我将其中一个终端中运行以下命令以在节点上加载一些负载
# stress -c 18 -i 13 -m 3 stress: info: [5200] dispatching hogs: 18 cpu, 13 io, 3 vm, 0 hdd

所以这里的结果几乎与吞吐量性能相同，因为 CPU 使用率始终处于 C0 状态。

注意：默认情况下，如果 powerstat 在没有任何参数的情况下执行，那么它将以 1 秒的间隔收集 60 个示例。
