Fields
| Name | Value | Description |
|---|---|---|
| NoError | 0 | The write was successful. |
| NoFreeBuffers | 1 | The session ran out of free buffers to write to. This can occur during high event rates because the disk subsystem is overloaded or the number of buffers is too small. Rather than blocking until more buffers become available, the event is dropped. Consider increasing the number and size of the buffers for the session, or reducing the number of events written or the size of the events. |
| EventTooBig | 2 | The event is larger than the session buffer size; events cannot span buffers. |
Remarks
To get an instance of this enumeration, call the EventProvider.GetLastWriteEventError method.
The EventProvider.WriteEvent, EventProvider.WriteMessageEvent, and EventProvider.WriteTransferEvent methods set this value if they fail to write the event.
