서버 모니터링을 해보고 싶어서 메모리 체크하는 부분을 찾아봤는데,

생각보다 잘 안보이더라...

근데 찾았당~

아래와 같은 클래스를 붙여놓고...

//메모리 체크

public static class PerformanceInfo

{

[DllImport("psapi.dll", SetLastError = true)]

[return: MarshalAs(UnmanagedType.Bool)]

public static extern bool GetPerformanceInfo([Out] out PerformanceInformation PerformanceInformation, [In] int Size);

[StructLayout(LayoutKind.Sequential)]

public struct PerformanceInformation

{

public int Size;

public IntPtr CommitTotal;

public IntPtr CommitLimit;

public IntPtr CommitPeak;

public IntPtr PhysicalTotal;

public IntPtr PhysicalAvailable;

public IntPtr SystemCache;

public IntPtr KernelTotal;

public IntPtr KernelPaged;

public IntPtr KernelNonPaged;

public IntPtr PageSize;

public int HandlesCount;

public int ProcessCount;

public int ThreadCount;

}

public static Int64 GetPhysicalAvailableMemoryInMiB()

{

PerformanceInformation pi = new PerformanceInformation();

if (GetPerformanceInfo(out pi, Marshal.SizeOf(pi)))

{

return Convert.ToInt64((pi.PhysicalAvailable.ToInt64() * pi.PageSize.ToInt64() / 1048576));

}

else

{

return -1;

}

}

public static Int64 GetTotalMemoryInMiB()

{

PerformanceInformation pi = new PerformanceInformation();

if (GetPerformanceInfo(out pi, Marshal.SizeOf(pi)))

{

return Convert.ToInt64((pi.PhysicalTotal.ToInt64() * pi.PageSize.ToInt64() / 1048576));

}

else

{

return -1;

}

}

}

아래와 같이 사용할 수 있다.

Int64 phav = PerformanceInfo.GetPhysicalAvailableMemoryInMiB();

Int64 tot = PerformanceInfo.GetTotalMemoryInMiB();

decimal percentFree = ((decimal)phav / (decimal)tot) * 100;

decimal percentOccupied = 100 - percentFree;

Console.WriteLine("Available Physical Memory (MiB) " + phav.ToString());

Console.WriteLine("Total Memory (MiB) " + tot.ToString());

Console.WriteLine("Free (%) " + percentFree.ToString());

Console.WriteLine("Occupied (%) " + percentOccupied.ToString());

Console.ReadLine();
