Keterangan
ASP.NET pemantauan kesehatan memungkinkan staf produksi dan operasi untuk mengelola aplikasi Web yang disebarkan. Namespace System.Web.Management berisi jenis peristiwa kesehatan yang bertanggung jawab untuk mengemas data status kesehatan aplikasi dan jenis penyedia yang bertanggung jawab untuk memproses data ini. Ini juga berisi jenis pendukung yang membantu selama pengelolaan peristiwa kesehatan.
Kelas WebBaseEvent adalah akar pohon pewarisan untuk semua jenis peristiwa pemantauan kesehatan ASP.NET. Ini menggunakan WebApplicationInformation kelas untuk mendapatkan informasi aplikasi yang tersedia untuk kelas turunannya.
Catatan
Dalam kebanyakan kasus, Anda akan dapat menggunakan jenis pemantauan kesehatan ASP.NET seperti yang diterapkan, dan Anda akan mengontrol sistem pemantauan kesehatan dengan menentukan nilai di bagian <healthMonitoring>
konfigurasi. Anda juga dapat memperoleh dari jenis pemantauan kesehatan untuk membuat peristiwa dan penyedia kustom Anda sendiri. Untuk contoh berasal dari WebBaseEvent kelas , lihat contoh yang disediakan dalam topik ini.
Catatan Bagi Inheritor
Saat Anda memformat informasi peristiwa kustom untuk ditampilkan, ganti FormatCustomEventDetails(WebEventFormatter) metode daripada ToString metode . Ini akan menghindari penimpaan atau perubahan dengan informasi sistem sensitif.
Kode peristiwa yang Anda tentukan untuk peristiwa kustom Anda harus lebih besar dari WebExtendedBase.
