Put Log Events

cloudwatchlogs_put_log_events R Documentation

Uploads a batch of log events to the specified log stream

Description

Uploads a batch of log events to the specified log stream.

The sequence token is now ignored in put_log_events actions. put_log_events actions are always accepted and never return InvalidSequenceTokenException or DataAlreadyAcceptedException even if the sequence token is not valid. You can use parallel put_log_events 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, put_log_events 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 put_log_events returns "UnrecognizedClientException" the most likely cause is a non-valid Amazon Web Services access key ID or secret key.

Usage

cloudwatchlogs_put_log_events(logGroupName, logStreamName, logEvents,
  sequenceToken, entity)

Arguments

logGroupName

[required] The name of the log group.

logStreamName

[required] The name of the log stream.

logEvents

[required] The log events.

sequenceToken

The sequence token obtained from the response of the previous put_log_events call.

The sequenceToken parameter is now ignored in put_log_events actions. put_log_events actions are now accepted and never return InvalidSequenceTokenException or DataAlreadyAcceptedException even if the sequence token is not valid.

entity

Reserved for future use.

Value

A list with the following syntax: 

list(
  nextSequenceToken = "string",
  rejectedLogEventsInfo = list(
    tooNewLogEventStartIndex = 123,
    tooOldLogEventEndIndex = 123,
    expiredLogEventEndIndex = 123
  ),
  rejectedEntityInfo = list(
    errorType = "InvalidEntity"|"InvalidTypeValue"|"InvalidKeyAttributes"|"InvalidAttributes"|"EntitySizeTooLarge"|"UnsupportedLogGroupType"|"MissingRequiredFields"
  )
)

Request syntax

svc$put_log_events(
  logGroupName = "string",
  logStreamName = "string",
  logEvents = list(
    list(
      timestamp = 123,
      message = "string"
    )
  ),
  sequenceToken = "string",
  entity = list(
    keyAttributes = list(
      "string"
    ),
    attributes = list(
      "string"
    )
  )
)
