WebAuditEvent Class
Serves as the base class for all ASP.NET health-monitoring audit events.
Assembly: System.Web (in System.Web.dll)
The WebAuditEvent type exposes the following members.
| Name | Description | |
|---|---|---|
![]() | WebAuditEvent(String, Object, Int32) | Infrastructure. Initializes a new instance of the WebAuditEvent class using the supplied parameters. |
![]() | WebAuditEvent(String, Object, Int32, Int32) | Infrastructure. Initializes a new instance of the WebAuditEvent class with specified event parameters. |
| Name | Description | |
|---|---|---|
![]() | EventCode | Gets the code value associated with the event. (Inherited from WebBaseEvent.) |
![]() | EventDetailCode | Gets the event detail code. (Inherited from WebBaseEvent.) |
![]() | EventID | Gets the identifier associated with the event. (Inherited from WebBaseEvent.) |
![]() | EventOccurrence | Gets a counter that represents the number of times the event has occurred. (Inherited from WebBaseEvent.) |
![]() | EventSequence | Gets the number of times the event has been raised by the application. (Inherited from WebBaseEvent.) |
![]() | EventSource | Gets the object that raises the event. (Inherited from WebBaseEvent.) |
![]() | EventTime | Gets the time when the event was raised. (Inherited from WebBaseEvent.) |
![]() | EventTimeUtc | Gets the time when the event was raised. (Inherited from WebBaseEvent.) |
![]() | Message | Gets the message that describes the event. (Inherited from WebBaseEvent.) |
![]() | ProcessInformation | Gets information about the ASP.NET application-hosting process. (Inherited from WebManagementEvent.) |
![]() | RequestInformation | Get the information associated with the Web request. |
| Name | Description | |
|---|---|---|
![]() | Equals(Object) | Determines whether the specified Object is equal to the current Object. (Inherited from Object.) |
![]() | Finalize | Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.) |
![]() | FormatCustomEventDetails | Provides standard formatting of the event information. (Inherited from WebBaseEvent.) |
![]() | GetHashCode | Serves as a hash function for a particular type. (Inherited from Object.) |
![]() | GetType | Gets the Type of the current instance. (Inherited from Object.) |
![]() | IncrementPerfCounters | Infrastructure. Used internally to increment performance counters. (Inherited from WebBaseEvent.) |
![]() | MemberwiseClone | Creates a shallow copy of the current Object. (Inherited from Object.) |
![]() | Raise() | Raises an event by notifying any configured provider that the event has occurred. (Inherited from WebBaseEvent.) |
![]() | ToString() | Formats event information for display purposes. (Inherited from WebBaseEvent.) |
![]() | ToString(Boolean, Boolean) | Formats event information for display purposes. (Inherited from WebBaseEvent.) |
ASP.NET health monitoring allows production and operations staff to manage deployed Web applications. 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. It also contains supporting types that help during the management of health events.
The WebAuditEvent class is the base class from which the ASP.NET health-monitoring audit-event classes derive. The audit events generate information about security-related operations in a Web application and provide both a success and failure event for each audited operation.
The health-monitoring system can audit both successful and unsuccessful events, which means an application can be monitored for both normal and malfunctioning conditions. By default, only the failure audit events are recorded.
The following operations are audited by ASP.NET, and may generate success-or-failure health-monitoring audit events:
Login attempts made by users of an ASP.NET application. For more details about this auditing, see WebAuthenticationSuccessAuditEvent and WebSuccessAuditEvent.
Security-related events, such as authentication failures, failed resource access attempts, and other security-related events. The log of these events can be useful when investigating an intrusion or attack on the application. By default, no auditing support is provided for authorization failures of anonymous users. For more details about failure event audits, see WebAuthenticationFailureAuditEvent and WebFailureAuditEvent.
Custom events raised by an ASP.NET application. You can audit custom events by extending the functionality provided by the WebAuditEvent class and derived classes
Note |
|---|
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. You can also derive from the health-monitoring types to create your own custom events and providers. For an example of deriving from the WebAuditEvent class, see the example provided in this topic. |
When formatting your custom event information for display, override the FormatCustomEventDetails method rather than the ToString method. This will avoid overwriting or tampering with sensitive system information.
The following code example shows how to derive from the WebAuditEvent class to create a custom audit event.
The following is an excerpt of the configuration file that enables ASP.NET to use the event.
