簡單的創(chuàng)建一個性能計數(shù)器
一、性能監(jiān)控的作用
網(wǎng)站設計、成都網(wǎng)站制作介紹好的網(wǎng)站是理念、設計和技術(shù)的結(jié)合。創(chuàng)新互聯(lián)擁有的網(wǎng)站設計理念、多方位的設計風格、經(jīng)驗豐富的設計團隊。提供PC端+手機端網(wǎng)站建設，用營銷思維進行網(wǎng)站設計、采用先進技術(shù)開源代碼、注重用戶體驗與SEO基礎，將技術(shù)與創(chuàng)意整合到網(wǎng)站之中，以契合客戶的方式做到創(chuàng)意性的視覺化效果。
性能監(jiān)控可以用于獲取關于應用程序的正常行為的一般消息，性能監(jiān)控是一個強大的工具，有助于理解系統(tǒng)的工作負載，觀察變化和趨勢，尤其是運行在服務器上的應用程序
二、性能監(jiān)控類（System.Diagnostics）：
PerformanceCounter類：監(jiān)控計數(shù)與寫入計數(shù)。還可以使用這個類創(chuàng)建新的性能類別
PerformanceCounterCategory類：可以查看所有的已有的類別，以及創(chuàng)建類別?？梢砸跃幊痰姆绞将@得一個類別中的所有計數(shù)器
performanceCounterInstall類：用于安裝性能計數(shù)器
需要引用WindowsBase
三、創(chuàng)建性能類別（兩種創(chuàng)建方式）：
1，圖形化創(chuàng)建：
2，代碼創(chuàng)建+操作（可以監(jiān)控不同應用程序的性能計數(shù)）：
