设置容器CPU使用百分比
下面是一个示范代码,使用Docker SDK for Python获取运行中的所有容器的CPU使用率: importdocker client=docker.from_env()containers=client.containers.list()forcontainerincontainers:stats=container.stats(stream=False)cpu_percent=stats['cpu_stats']['cpu_usage']['total_usage']print(f"Container ID:{containe...
cpuPercent = (cpuDelta / systemDelta) * float64(len(v.CpuStats.CpuUsage.PercpuUsage))...

将步骤 2 中的system_cpu_usage_delta转换为 ns 表示,即system_cpu_usage_delta * nanoSecondsPerSecond / clockTicksPerSecond,记为system_cpu_total_delta; 最后计算容器的 CPU 利用率,即CPU_percent = container_cpu_total_delta / system_cpu_total_delta * getNumberOnlineCPUs,其中getNumberOnlineCPUs为系统...
$ docker stats --no-stream --format \"{\"container\":\"{{ .Container }}\",\"memory\":{\"raw\":\"{{ .MemUsage }}\",\"percent\":\"{{ .MemPerc }}\"},\"cpu\":\"{{ .CPUPerc }}\"}" 总结 通过docker stats 命令我们可以看到容器使用系统资源的情况。这为我们进一步的约束容器...
cpu_percent defines the usable percentage of the available CPUs. cpu_shares cpu_shares defines, as integer value, a service container's relative CPU weight versus other containers. cpu_period cpu_period configures CPU CFS (Completely Fair Scheduler) period when a platform is based on Linux kernel...
