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 WebEventBufferFlushInfo class defines values that identify the buffer's current status. An instance of the class is passed as a parameter to the ProcessEventFlush method that processes the messages that have been buffered. ASP.NET health monitoring calls this method when the flushing of the buffer is required. This is determined by the parameters defined by the bufferModes element in the healthMonitoring configuration section.

System_CAPS_noteNote

By design, the buffering mechanism might drop some events in order to keep pace with the incoming events. It is up to the user to adjust this mechanism by properly modifying the bufferModes element in the healthMonitoring configuration section.

The following code example shows how to use the WebEventBufferFlushInfo class. This code example is part of a larger example provided for the BufferedWebEventProvider class.


// Processes the messages that have been buffered.
// It is called by the ASP.NET when the flushing of 
// the buffer is required.
public override void ProcessEventFlush(
    WebEventBufferFlushInfo flushInfo)
{

    // Customize event information to be sent to 
    // the Windows Event Viewer Application Log.
    customInfo.AppendLine(
        "SampleEventLogWebEventProvider buffer flush.");

    customInfo.AppendLine(
        string.Format("NotificationType: {0}",
        GetNotificationType(flushInfo)));

    customInfo.AppendLine(
        string.Format("EventsInBuffer: {0}",
        GetEventsInBuffer(flushInfo)));

    customInfo.AppendLine(
        string.Format(
        "EventsDiscardedSinceLastNotification: {0}",
        GetEventsDiscardedSinceLastNotification(flushInfo)));


    // Read each buffered event and send it to the
    // Application Log.
    foreach (WebBaseEvent eventRaised in flushInfo.Events)
        customInfo.AppendLine(eventRaised.ToString());

    // Store the information in the specified file.
    StoreToFile(customInfo, logFilePath, FileMode.Append);
}
