示例
下面的示例分为两部分。The following example has two parts. 第一种是配置文件的摘录,使 ASP.NET 可以使用使用该类型的自定义事件 WebProcessInformation 。The first is an excerpt of a configuration file that enables ASP.NET to use a custom event that uses the WebProcessInformation type.
第二个示例演示如何实现自定义事件。The second shows how to implement the custom event.
确保在适当的时间引发自定义事件,即,当引发其替换的等效系统运行状况事件时。Ensure that your custom event is raised at the proper time, that is, when the equivalent system health event it replaces would be raised.

// Implements a custom WebBaseEvent type that
// uses WebProcessInformation.
public class SampleWebProcessInformation:

{
private StringBuilder eventInfo;
// Instantiate SampleWebProcessInformation.
public SampleWebProcessInformation(string msg,
object eventSource, int eventCode) :
base(msg, eventSource, eventCode)
{
// Perform custom initialization.
eventInfo = new StringBuilder();
eventInfo.Append(string.Format(
"Event created at: {0}",
EventTime.ToString()));
}
// Raises the event.
public override void Raise()
{
// Perform custom processing.
eventInfo.Append(string.Format(
"Event raised at: {0}",
EventTime.ToString()));
// Raise the event.
base.Raise();
}
public string GetAccountName()
{
// Get the name of the account.
return (string.Format(
"Account name: {0}",
ProcessInformation.AccountName));
}
public string GetProcessId()
{
// Get the process identifier.
return (string.Format(
"Process Id: {0}",
ProcessInformation.ProcessID.ToString()));
}
public string GetProcessName()
{
// Get the requests in execution.
return (string.Format(
"Process name: {0}",
ProcessInformation.ProcessName));
}
//Formats Web request event information.
public override void FormatCustomEventDetails(
WebEventFormatter formatter)
{
base.FormatCustomEventDetails(formatter);
// Add custom data.
formatter.AppendLine("Custom Process Information:");
formatter.IndentationLevel += 1;
// Display the process information.
formatter.AppendLine(GetAccountName());
formatter.AppendLine(GetProcessId());
formatter.AppendLine(GetProcessName());
formatter.IndentationLevel -= 1;
formatter.AppendLine(eventInfo.ToString());
}
}
}

注解
ASP.NET health monitoring 允许生产和运营人员管理已部署的 Web 应用程序。ASP.NET health monitoring allows production and operations staff to manage deployed Web applications. System.Web.Management命名空间包含负责打包应用程序运行状况数据的运行状况事件类型,以及负责处理此数据的提供程序类型。The System.Web.Management namespace contains the health-event types responsible for packaging application health-status data, and the provider types responsible for processing this data. 它还包含在运行状况事件的管理过程中可帮助的支持类型。It also contains supporting types that help during the management of health events.
类的实例 WebProcessInformation 包含使用从类型派生的任何类型获得的信息 WebManagementEvent 。Instances of the WebProcessInformation class contain information that is obtained using any of the types derived from the WebManagementEvent type.
应用程序需要适当的权限才能访问此类型提供的受保护信息。Your application needs the appropriate permissions to access protected information provided by this type.
下面的示例摘自配置文件,你可以使用该配置文件来启用 ASP.NET,以便记录包含进程信息的错误事件。The following example is an excerpt of the configuration file you could use to enable ASP.NET to log error events that contain process information.
<healthMonitoring
enabled="true" heartBeatInterval="0">
<rules>
<add
name="All Errors Default"
eventName="All Errors"
provider="EventLogProvider"
profile="Default"
minInterval="00:01:00" />
</rules>
</healthMonitoring>
备注
在大多数情况下,你将能够使用已实现的 ASP.NET health 监视类型,并且将通过在 "配置" 部分中指定值来控制运行状况监视系统 healthMonitoring 。In most cases you will be able to use the ASP.NET health-monitoring types as implemented, and you will control the health-monitoring system by specifying values in the healthMonitoring configuration section. 还可以从运行状况监视类型派生,以创建自己的自定义事件和提供程序。You can also derive from the health-monitoring types to create your own custom events and providers. 有关创建自定义事件类的示例,请参阅 "示例" 部分。For an example of creating a custom event class, see the Example section.
