Sol*_*s17 7 c# console multicore cpu-speed
特技是我还需要能够在多核机器上完成.我在C#的教育有点破碎.我已经管理了以下代码.谁能帮我吗？我尝试使用"_Total"标志,我尝试修改一些其他代码片段,看起来他们试图检测核心数量.我被告知他们不包括HT,只支持物理非逻辑处理器.我试图让它做到这两点.显然他们是一种手动执行此操作的方法
("Process", "% Processor Time", "1" process.ProcessName))
("Process", "% Processor Time", "2" process.ProcessName))
("Process", "% Processor Time", "3" process.ProcessName))
但是,如果内核不存在,我发现硬件不起作用.我希望我能遇到更灵活的事情.我一直在研究这几天几小时,我要把头发拉出来.

编辑::我对代码进行了以下更改,以便根据建议和基本的方法解决我的问题.
foreach (Process process in runningNow)
{
using (PerformanceCounter cpuUsage = new PerformanceCounter("Process", "% Processor Time", "_Total"))
using (PerformanceCounter pcProcess = new PerformanceCounter("Process", "% Processor Time", process.ProcessName))
using (PerformanceCounter memProcess = new PerformanceCounter("Memory", "Available MBytes"))
{
if (process.ProcessName == procName)
{
StreamWriter OurStream;
OurStream = File.AppendText("c:\\CPUMON.txt");
Console.WriteLine("");
OurStream.WriteLine("");
// Prime the Performance Counters
pcProcess.NextValue();
cpuUsage.NextValue();
Thread.Sleep(100);
isprimed = true;
double cpuUse = Math.Round(pcProcess.NextValue() / cpuUsage.NextValue() * 100, 2);
// Check for Not-A-Number (Division by Zero)
if (Double.IsNaN(cpuUse))
cpuUse = 0;
//Get CPU Usage
Console.ForegroundColor = ConsoleColor.Red;
Console.WriteLine("Process: `{0}' CPU Usage: {1}%", process.ProcessName, Convert.ToInt32(cpuUse));
OurStream.WriteLine("Process: `{0}' CPU Usage: {1}%", process.ProcessName, Convert.ToInt32(cpuUse));
// Get Process Memory Usage
Console.ForegroundColor = ConsoleColor.Green;
double memUseage = process.PrivateMemorySize64 / 1048576;
Console.WriteLine("Process: `{0}' Memory Usage: {1}MB", process.ProcessName, memUseage);
OurStream.WriteLine("Process: `{0}' Memory Usage: {1}MB", process.ProcessName, memUseage);
// Get Total RAM free
Console.ForegroundColor = ConsoleColor.Cyan;
float mem = memProcess.NextValue();
Console.WriteLine("During: `{0}' RAM Free: {1}MB", process.ProcessName, mem);
OurStream.WriteLine("During: `{0}' RAM Free: {1}MB", process.ProcessName, mem);
//Record and close stream
Console.ForegroundColor = ConsoleColor.Yellow;
System.DateTime newDate = System.DateTime.Now;
Console.WriteLine("Recorded: {0}", newDate);
OurStream.WriteLine("Recorded: {0}", newDate);
OurStream.Close();
Thread.Sleep(59900);

您只能每100毫秒读取性能计数器,或者时间太小而无法获得准确的读数,如果您每100毫秒读取一次以上,它将始终报告0或100%的使用率.因为您调用了NextValue()两次(一次用于文件,一次用于您的流),第二次读取将是自上一次读取之前的行以来的用法.
将您的代码更改为:
foreach (Process process in runningNow.Where(x => x.ProcessName == procName)
{
using (PerformanceCounter pcProcess = new PerformanceCounter("Process", "% Processor Time", process.ProcessName))
using (PerformanceCounter memProcess = new PerformanceCounter("Memory", "Available MBytes"))
{
pcProcess.NextValue();
Thread.Sleep(60000);
StreamWriter OurStream;
OurStream = File.AppendText("c:\\CPUMON.txt");
Console.WriteLine("");
OurStream.WriteLine("");
Console.ForegroundColor = ConsoleColor.Red;
float cpuUseage = pcProcess.NextValue();
Console.WriteLine("Process: '{0}' CPU Usage: {1}%", process.ProcessName, cpuUseage);
OurStream.WriteLine("Process: '{0}' CPU Usage: {1}%", process.ProcessName, cpuUseage);
Console.ForegroundColor = ConsoleColor.Green;
float memUseage = memProcess.NextValue();
Console.WriteLine("Process: '{0}' RAM Free: {1}MB", process.ProcessName, memUseage);
OurStream.WriteLine("Process: '{0}' RAM Free: {1}MB", process.ProcessName, memUseage);
}
}
可能还有其他问题导致您出现问题,但是两次调用NextValue是第一个跳出来的问题.
说明:
NextValue当您请求NextValue过快时仅报告0或100%的原因是,如果您当前正在执行代码,则是布尔因子.
那么性能计数器正在做的是提出这样的问题:
在性能计数器最后一次读取和现在之间,有多少时间切片从进程X执行代码？
性能计数器使用的那些时间片的大小是100ms,所以如果你低于100ms你基本上要求
性能计数器记录的最后一个时间片是否包含进程X执行的代码？
你可以得到的唯一两个答案是"不"(0%)或"是"(100%).
