範例

下列程式碼範例有兩個部分。 第一個是組態檔的摘錄,可讓 ASP.NET 使用使用 WebProcessStatistics 類型的自訂事件。 第二個顯示如何實作這個自訂事件。

請確定您的自訂事件會在適當的時間引發,也就是說,它會引發其取代的對等系統健康情況事件。

備註

ASP.NET 健康情況監視可讓生產與作業人員管理已部署的 Web 應用程式。 System.Web.Management命名空間包含負責封裝應用程式健康狀態資料的健全狀況事件種類,以及負責處理此資料的提供者類型。 它也包含支援類型,可協助管理健康情況事件。

類別的 WebProcessStatistics 實例包含使用 WebHeartbeatEvent 型別取得的資訊。

注意

在大部分情況下,您將能夠使用實作 ASP.NET 健康情況監視類型,而且您會在組態區段中指定值 healthMonitoring 來控制健康情況監視系統。 您也可以從健康情況監視類型衍生,以建立您自己的自訂事件和提供者。 如需建立自訂事件類別的範例,請參閱本主題中提供的範例。

以下是可用來啟用 ASP.NET 記錄包含進程統計資料的活動訊號事件的組態檔摘要。
