Uploads a batch of log events to the specified log stream.
You must include the sequence token obtained from the response of the previous call.
An upload in a newly created log stream does not require a sequence token. You can
also get the sequence token in the expectedSequenceToken field from InvalidSequenceTokenException.
If you call PutLogEvents twice within a narrow time period using the
same value for sequenceToken, both calls might be successful or one might
be rejected.
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 older than 14 days or older 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 the event occurred, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC. (In AWS Tools for PowerShell and the AWS 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.
The maximum number of log events in a batch is 10,000.
There is a quota of 5 requests per second per log stream. Additional requests are throttled. This quota can't be changed.
If a call to PutLogEvents returns "UnrecognizedClientException" the most
likely cause is an invalid AWS 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. |
| 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. |
| ResourceNotFoundException | The specified resource does not exist. |
| ServiceUnavailableException | The service cannot complete the request. |
| UnrecognizedClientException | The most likely cause is an invalid AWS access key ID or secret key. |
