目的：公司服務(wù)器IIS有十幾個應(yīng)用地址池，總在不經(jīng)意間停掉一個，停止線系統(tǒng)日志里會有一大堆警告日志，然后就停掉了，分析了好幾次，網(wǎng)上有人說是某一個網(wǎng)站的問題應(yīng)該查網(wǎng)站，但是網(wǎng)站又有那么多地址，誰知道從哪個請求開始就把應(yīng)用地址池給弄掛掉了啊，白天還好隨時有人看著服務(wù)器在，晚上停了就麻煩了，所有有了需求，自動監(jiān)控應(yīng)用地址池。其實方法很簡單，就是定時對應(yīng)用地址池遍歷一遍，檢查是否有未啟動的應(yīng)用地址池，有的話就執(zhí)行啟動命令。

代碼如下:
/// <summary>
        /// IIS應(yīng)用地址池監(jiān)控方法
        /// </summary>
        private void IISAppPools()
        {
            try
            {
                string entPath = "IIS://LOCALHOST/W3SVC/AppPools";
                while (true)
                {
                    DirectoryEntry rootEntry = new DirectoryEntry(entPath);
                    foreach (DirectoryEntry AppPool in rootEntry.Children)
                    {
                        if (AppPool.Properties["AppPoolState"].Value.ToString() != "2")
                        {
                            LogHelper.Wirte("監(jiān)控到" + AppPool.Name + "應(yīng)用地址池停止.");
                            AppPool.Invoke("Start", null);
                            AppPool.CommitChanges();
                            LogHelper.Wirte(AppPool.Name + "應(yīng)用地址池已成功啟動.");
