Question

我正在尝试在本地数据库管理系统上做一些基准测试。我需要提出一个GUI来显示像

这样的信息

每个核心的cpu使用情况
内存使用
HDD I / O
.. etc

没有使用Vb.net但我可以使用p / invoke或本机代码（如果需要）

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来访问使用C＃，asp.net webforms，framework 4.0 - 4.02的实时硬件（当前版本是windows 7 x64）信息和统计信息。现在，我所知道的是如何操纵和访问“进程”，但不能按照本文的要求进行绑定。

JQuery Ajax部分用于更新页面而不刷新我正在使用

$('document').ready(function () {
    // alert("JeuryIsOnline");
    $('#DivRobCounterRes').fadeTo(4, 0);

    $('.Span_imgMemeBase').click(
        function () {

            var Spars = [];
            Spars.push("egnition");

            for (i = 1; i < 11; i++)

            jQuerySendCfrm(Spars);
     });


});    // EndJquery Ready Code 



function jQuerySendCfrm(resluts) {

    var SentClientinfo = []
    SentClientinfo.push({ key: "SentClientinfo", value: resluts });
    var CurrpageURL = "default.aspx/";
    var WebmethodName = "StartTest";
    var StageIdentifyer = "stage1";
    var Post_TargetUrl = CurrpageURL + WebmethodName;

    jQueryAajaxNoPostBack(Post_TargetUrl, SentClientinfo, StageIdentifyer);
}


function jQueryAajaxNoPostBack(targetUrl, passedSentPars, StageIdentifyer) {
//////////    alert(JSON.stringify({ SentPars: passedSentPars }));
    $.ajax({
        type: 'POST',
        url: targetUrl,
        data: JSON.stringify({ SentPars: passedSentPars }),

        contentType: "application/json; charset=utf-8",
        dataType: "json",

        success: function (response) {
            if (StageIdentifyer == "stage1") {
                var htmlret = response.d;
                getCallBackToGenerateSeYaMsg(htmlret);
            }
//            else if (StageIdentifyer == "stage2") {
//                var html4TableHeaders = response.d;
//                getCallBackToGenerateInnerHtmlDiv(html4TableHeaders);
//                //alert(response.d)
//            }

    },
    error: function (response) {
    ////////            alert(response.status + ' ' + response.statusText);

           }
    });
}

function getCallBackToGenerateSeYaMsg(html) {

            $('#DivRobCounterRes').fadeTo(400, 1);
            $('#DivRobCounterRes').append(html);
}
