Uploads a batch of log events to the specified log stream.
The sequence token is now ignored in PutLogEvents actions. PutLogEvents
actions are always accepted and never return InvalidSequenceTokenException
or DataAlreadyAcceptedException even if the sequence token is not valid. You
can use parallel PutLogEvents actions on the same log stream.
The batch of events must satisfy the following constraints:
The maximum batch size is 1,048,576 bytes. This size is calculated as the sum of all event messages in UTF-8, plus 26 bytes for each log event.
None of the log events in the batch can be more than 2 hours in the future.
None of the log events in the batch can be more than 14 days in the past. Also, none of the log events can be from earlier than the retention period of the log group.
The log events in the batch must be in chronological order by their timestamp. The
timestamp is the time that the event occurred, expressed as the number of milliseconds
after Jan 1, 1970 00:00:00 UTC. (In Amazon Web Services Tools for PowerShell
and the Amazon Web Services SDK for .NET, the timestamp is specified in .NET format:
yyyy-mm-ddThh:mm:ss. For example, 2017-09-15T13:45:30.)
A batch of log events in a single request cannot span more than 24 hours. Otherwise, the operation fails.
Each log event can be no larger than 256 KB.
The maximum number of log events in a batch is 10,000.
The quota of five requests per second per log stream has been removed. Instead, PutLogEvents
actions are throttled based on a per-second per-account quota. You can request an
increase to the per-second throttling quota by using the Service Quotas service.
If a call to PutLogEvents returns "UnrecognizedClientException" the most likely
cause is a non-valid Amazon Web Services access key ID or secret key.
This is an asynchronous operation using the standard naming convention for .NET 4.5 or higher. For .NET 3.5 the operation is implemented as a pair of methods using the standard naming convention of BeginPutLogEvents and EndPutLogEvents.

public virtual Task<PutLogEventsResponse> PutLogEventsAsync( PutLogEventsRequest request, CancellationToken cancellationToken )
Container for the necessary parameters to execute the PutLogEvents service method.
A cancellation token that can be used by other objects or threads to receive notice of cancellation.
| Exception | Condition |
|---|---|
| DataAlreadyAcceptedException | The event was already logged. PutLogEvents actions are now always accepted and never return DataAlreadyAcceptedException regardless of whether a given batch of log events has already been accepted. |
| InvalidParameterException | A parameter is specified incorrectly. |
| InvalidSequenceTokenException | The sequence token is not valid. You can get the correct sequence token in the expectedSequenceToken field in the InvalidSequenceTokenException message. PutLogEvents actions are now always accepted and never return InvalidSequenceTokenException regardless of receiving an invalid sequence token. |
| ResourceNotFoundException | The specified resource does not exist. |
| ServiceUnavailableException | The service cannot complete the request. |
| UnrecognizedClientException | The most likely cause is an Amazon Web Services access key ID or secret key that's not valid. |
