c# - System.Management 资源监控统计信息，如 I/O、CPU、内存使用...等'

Question

我正在尝试对本地数据库管理系统进行一些基准测试。 我需要想出一个 GUI 来显示类似

的信息

• 每个核心的cpu使用情况
• 内存使用情况
• 硬盘输入/输出
• ..等

它将不使用 Vb.net，但如果需要我可以使用 p/invoke 或 native 代码

以下代码是:据我所知

Set objCimv2 = GetObject("winmgmts:root\cimv2")
Set objRefresher = CreateObject("WbemScripting.SWbemRefresher")

' Add items to the SWbemRefresher
' Without the SWbemRefreshableItem.ObjectSet call,
' the script will fail
Set objMemory = objRefresher.AddEnum _
    (objCimv2, _ 
    "Win32_PerfFormattedData_PerfOS_Memory").ObjectSet
Set objDiskQueue = objRefresher.AddEnum _
    (objCimv2, _
    "Win32_PerfFormattedData_PerfDisk_LogicalDisk").ObjectSet
Set objQueueLength = objRefresher.AddEnum _
    (objCimv2, _
    "Win32_PerfFormattedData_PerfNet_ServerWorkQueues").ObjectSet

' Initial refresh needed to get baseline values
objRefresher.Refresh
intTotalHealth = 0
' Do three refreshes to get data
For i = 1 to 3
    WScript.Echo "Refresh " & i
    For each intAvailableBytes in objMemory
        WScript.Echo "Available megabytes of memory: " _
            & intAvailableBytes.AvailableMBytes
        If intAvailableBytes.AvailableMBytes < 4 Then
            intTotalHealth = intTotalHealth + 1
        End If
    Next
    For each intDiskQueue in objDiskQueue
        WScript.Echo "Current disk queue length " & "Name: " _
            & intDiskQueue.Name & ":" _
            & intDiskQueue.CurrentDiskQueueLength
        If intDiskQueue.CurrentDiskQueueLength > 2 Then
            intTotalHealth = intTotalHealth + 1
        End If
    Next
    For each intServerQueueLength in objQueueLength
        WScript.Echo "Server work queue length: " _
            & intServerQueueLength.QueueLength
        If intServerQueueLength.QueueLength > 4 Then
            intTotalHealth = intTotalHealth + 1                       
        End If
    Wscript.Echo "  "
    Next
    If intTotalHealth > 0 Then
        Wscript.Echo "Unhealthy."
    Else
        Wscript.Echo "Healthy."
    End If
    intTotalHealth = 0
    Wscript.Sleep 5000
' Refresh data for all objects in the collection
    objRefresher.Refresh
Next

我正在寻找一个很好的 API 来使用 C#、asp.net webforms、framework 4.0 - 4.02 访问实时硬件(当前版本是 windows 7 x64)信息和统计数据。 目前我所知道的是如何操作和访问“进程”，但不按照本文的要求进行绑定(bind)。

JQuery Ajax 部分用于在不刷新的情况下更新我正在使用的页面

$('document').ready(function () {
