机器的 .net 核心 CPU 使用率 [英] .net core cpu usage for machine

问题描述

我最近从 c# 迁移到 .net 核心.在 c# 中，我用这个来获取 CPU 使用率:

I recently migrated from c# to .net core. In c# I use to get CPU usage with this:

PerformanceCounter cpuCounter;
PerformanceCounter ramCounter;

cpuCounter = new PerformanceCounter("Processor", "% Processor Time", "_Total");

public string getCurrentCpuUsage(){
            return cpuCounter.NextValue()+"%";
}

但是在 .net core PerformanceCounter 中不可用有什么解决方案?请给我一个建议.

but in .net core PerformanceCounter is not available what is the solution ? please give me an advice.

推荐答案

性能计数器不在 Linux 中，因此不在 NET Core 中.替代方式:

Performance counters are not in Linux thus not in NET Core. Alternative way:

private async Task<double> GetCpuUsageForProcess()
{
    var startTime = DateTime.UtcNow;
    var startCpuUsage = Process.GetProcesses().Sum(a => a.TotalProcessorTime.TotalMilliseconds);
    await Task.Delay(500);

    var endTime = DateTime.UtcNow;
    var endCpuUsage = Process.GetProcesses().Sum(a => a.TotalProcessorTime.TotalMilliseconds);
    var cpuUsedMs = endCpuUsage - startCpuUsage;
    var totalMsPassed = (endTime - startTime).TotalMilliseconds;
    var cpuUsageTotal = cpuUsedMs / (Environment.ProcessorCount * totalMsPassed);
    return cpuUsageTotal * 100;
}
