如何在容器中获取CPU％ [英] How to get CPU % inside a container

问题描述

我想在容器内获取docker stats。我们不能在container中使用docker stats命令。所以，我想使用cat / sys / fs / cgroup。如何获得CPU％。

I want to get docker stats inside a container. We cant use docker stats command inside container . So ,I want to use cat /sys/fs/cgroup. How to get CPU%.

推荐答案

有多种方法可以做到这一点。大多数在容器外部工作的CPU使用率测量方法也将在容器内部工作。

There are a variety of ways of doing this. Most methods of measuring CPU usage which work outside of a container will also work inside of a container.

例如，您可以使用mpstat。此命令将每十秒钟测量一次利用率：

For example, you can use mpstat. This command will measure utilization every ten seconds:

mpstat -u 10

它将每十秒打印一次报告，详细说明CPU空闲的频率，空闲时的操作以及时间戳。如果您希望获得更频繁的报告，可以更改 10参数。

It will print out a report every ten seconds, detailing how often the CPU was idle, what it was doing when it wasn't idle, and a timestamp. If you want a more frequent report, you can change the '10' parameter.
