Events

This section provides detailed information about what events are, event sources, event severity, and describes the Events view.

Events are occurrences on your cluster or member of some administrative interest. These events are generated by a range of objects and applications both within Application Center and throughout your network. These events are displayed in the Application Center Event view. All of the Windows 2000 Informational, Error, and Warning events and some of the Application Center Error events are also logged in the Windows Event Log. Thus, you can view these events in the Windows 2000 Event Viewer.

 Note   The Windows Event Log uses Greenwich Mean Time (GMT).

Product (Source of Events)

A wide range of objects, applications, and services generate events that Application Center Events and Performance Logging records and displays. The following table summarizes the three most important event categories.

Product (source of event)	Description
Windows 2000 events	All of the Windows 2000 events that are logged by Application Center, except Audit events.
Health Monitor events	Different than Health Monitor data collectors, these events are generated by Health Monitor when a data collector's status is changed by a threshold.
Application Center events	Certain events that are generated by the various services within Application Center, such as synchronization and load balancing. Some of the error events are also logged to the Windows 2000 Event Log.

Event Type (Severity)

Events signify occurrences of varying severity, such as Informational, Warning, and Error events. The following table describes event severity.

Icon	Event type	Description
	Informational	Describes the successful operation of an application, driver, or service (for example, when a network driver loads successfully).
	Warning	Indicates an event that is not necessarily significant, but might indicate a possible future problem (for example, low disk space).
	Error	Indicates a significant problem, such as data or functionality loss (for example, a service failed to load during start up).

 Note   The Success Audit and Failure Audit events are not directly applicable to Application Center, although they are relevant to Windows 2000 security.

Event Details and Troubleshooting Information

Application Center provides two additional sources of information about events:

• Event details, which is a longer description of the event that provides more information about the source of the event, the severity of the event, and other technical details that are useful for troubleshooting.

• Troubleshooting information, which is a detailed message that provides information about the meaning, severity, and effect of the event, as well as possible solutions and troubleshooting steps. Also included is a link to Microsoft Support Online (Product Support Services), which provides late-breaking information about the event, such as Knowledge Base articles and hot fixes.

  If Microsoft Support Online does not have any data about a particular event, a default page is provided with more generalized information about troubleshooting.

Understanding the Events View

The Events view in the Application Center snap-in shows relevant events and provides filtering and search capabilities. The following table describes the different fields and provides an example of an Application Center event.

Date	The date on which the event occurred.	3/13/2000
Time	The local time when the event occurred.	5:04:31 PM
Member	The name of the computer on which the event occurred.	CLUSTER05
Source	The process that raised the event.	Replication
Event ID	A numerical identifier for the event.	4023
Description	A brief description of the event.	The cluster member failed

Event Details

Event details provide more information about events than the Events view. This additional information includes the the event's source, a description of the event, and details about what is affected by the event.

Event property	Description
Icon	Specifies the severity: Informational, Warning, or Error.
Date	Indicates the local date on which the event was generated.
Time	Provides the local, 24-hour, time when the event was generated.
Member	Specifies the server that generated the event.
Event ID	A unique numerical identifier for the event.
Product	Indicates the product that generated the event (for example, Windows 2000, Application Center, or Health Monitor).
Source and category	Provides the specific part of the service that generated the event.
Description	Gives a longer explanation for the event, including what resources are affected and other technical information.

Links to Additional Event Information

Included in the Events view, for Application Center events only, are two links (for Warning and Error events) to troubleshooting information and Support Online information regarding the specific event.
