SysField.XML文件指定在日誌文件中存儲PerformanceCounter（）值所需的全部參數以及性能計數器的採樣時間。

：應用程序存儲日誌文件的文件夾。

：日誌文件的文件名。

：指定一個布爾值

：單個日誌文件存儲的最大記錄數

PerformanceCounter（）的採樣間隔

爲了天天生成一個日誌文件，咱們須要將MaxNumberRecordsInLogFile設置爲等於：

MaxNumberRecordsInLogFile =（一天中的第二個）/ PollingSysParamsInterval

即

若是咱們每1秒採樣一次（PollingSysParamsInterval = 1），則MaxNumberRecordsInLogFile = 86400secondi /（1秒）= 86400

使用存儲在app.config中的參數能夠定義咱們要包含在採樣中的性能參數以及性能計數器的結構（順序）。

app.config的完整結構報告以下：

<？xml version =「 1.0」？>

<Start>

<ADD key=「 NodeName」value=「 false」 />

<ADD key=「 CPUProcessorTime」value=「 true」 />

<ADD key=「 CPUPrivilegedTime」value=「 true」 />

<ADD key =「 MEMPoolNonPaged」 value =「 true」 />

<ADD key =「 DISKTime」 value =「 true」 />

<ADD key =「 HANDLECountCounter」 value =「 true」 />

<ADD key =「 THREADCount」 value =「 true「 />

<ADD key =「 CONTENTSwitches」 value =「 true」 />

<ADD key =「 SYSTEMCalls」 value =「 true」 />

<ADD key =「 NumProcess」 value =「 true」 />

<ADD key =「 NetTrafficSend」 value = 「 true」 /

鍵值的含義是比較清楚的，與每一個鍵關聯的值是布爾值：

• 等於「 true 」的值表示跟蹤性能計數器的值

• 等於「 false 」的值表示能夠跳過性能計數器的值  

編譯應用程序時，Visual Studio將在bin \ debug文件夾中自動建立一個名爲<您的應用程序名稱> .exe.config的文件。編譯應用程序時，app.config的內容將自動複製到此新的配置文件中。當將應用程序交付給最終用戶時，您必須交付exe和名爲<您的應用程序名稱> .exe.config的新配置文件，而不是app.config。用戶能夠在<您的應用程序名稱> .exe.config中修改數據從新啓動後，文件和應用程序將從配置文件讀取數據。在app.config中更改（key，value）的順序可肯定將性能計數器的其餘順序打印到控制檯和日誌文件中。

該項目使用名爲SysParams的公共類來存儲全部性能計數器。
