AWS CLI Command Reference

[ aws . logs ]

put-log-events

Description

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 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.

  • The maximum number of log events in a batch is 10,000.

  • There is a quota of five 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 a non-valid Amazon Web Services access key ID or secret key.

Options

--log-group-name (string)

The name of the log group.

--log-stream-name (string)

The name of the log stream.

--log-events (list)

The log events.

(structure)

Represents a log event, which is a record of activity that was recorded by the application or resource being monitored.

timestamp -> (long)

The time the event occurred, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC .

message -> (string)

The raw event message.

Shorthand Syntax:

timestamp=long,message=string ...

JSON Syntax:

[
  {
    "timestamp": long,
    "message": "string"
  }
  ...
]

--sequence-token (string)

The sequence token obtained from the response of the previous PutLogEvents call. An upload in a newly created log stream does not require a sequence token. You can also get the sequence token using DescribeLogStreams . 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.

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command. The generated JSON skeleton is not stable between versions of the AWS CLI and there are no backwards compatibility guarantees in the JSON skeleton generated.

Global Options

--debug (boolean)

Turn on debug logging.

--endpoint-url (string)

Override command’s default URL with the given URL.

--no-verify-ssl (boolean)

By default, the AWS CLI uses SSL when communicating with AWS services. For each SSL connection, the AWS CLI will verify SSL certificates. This option overrides the default behavior of verifying SSL certificates.

--no-paginate (boolean)

Disable automatic pagination.

--output (string)

The formatting style for command output.

  • json

  • text

  • table

  • yaml

  • yaml-stream

--query (string)

A JMESPath query to use in filtering the response data.

--profile (string)

Use a specific profile from your credential file.

--region (string)

The region to use. Overrides config/env settings.

--version (string)

Display the version of this tool.

--color (string)

Turn on/off color output.

  • on

  • off

  • auto

--no-sign-request (boolean)

Do not sign requests. Credentials will not be loaded if this argument is provided.

--ca-bundle (string)

The CA certificate bundle to use when verifying SSL certificates. Overrides config/env settings.

--cli-read-timeout (int)

The maximum socket read time in seconds. If the value is set to 0, the socket read will be blocking and not timeout. The default value is 60 seconds.

--cli-connect-timeout (int)

The maximum socket connect time in seconds. If the value is set to 0, the socket connect will be blocking and not timeout. The default value is 60 seconds.

--cli-binary-format (string)

The formatting style to be used for binary blobs. The default format is base64. The base64 format expects binary blobs to be provided as a base64 encoded string. The raw-in-base64-out format preserves compatibility with AWS CLI V1 behavior and binary values must be passed literally. When providing contents from a file that map to a binary blob fileb:// will always be treated as binary and use the file contents directly regardless of the cli-binary-format setting. When using file:// the file contents will need to properly formatted for the configured cli-binary-format.

  • base64

  • raw-in-base64-out

--no-cli-pager (boolean)

Disable cli pager for output.

--cli-auto-prompt (boolean)

Automatically prompt for CLI input parameters.

--no-cli-auto-prompt (boolean)

Disable automatically prompt for CLI input parameters.

Examples

Note

To use the following examples, you must have the AWS CLI installed and configured. See the Getting started guide in the AWS CLI User Guide for more information.

Unless otherwise stated, all examples have unix-like quotation rules. These examples will need to be adapted to your terminal’s quoting rules. See Using quotation marks with strings in the AWS CLI User Guide .

The following command puts log events to a log stream named 20150601 in the log group my-logs:

aws logs put-log-events --log-group-name my-logs --log-stream-name 20150601 --log-events file://events

Output:

{
    "nextSequenceToken": "49542672486831074009579604567656788214806863282469607346"
}

The above example reads a JSON array of events from a file named events in the current directory:

[
  {
    "timestamp": 1433190184356,
    "message": "Example Event 1"
  },
  {
    "timestamp": 1433190184358,
    "message": "Example Event 2"
  },
  {
    "timestamp": 1433190184360,
    "message": "Example Event 3"
  }
]

Each subsequent call requires the next sequence token provided by the previous call to be specified with the sequence token option:

aws logs put-log-events --log-group-name my-logs --log-stream-name 20150601 --log-events file://events2 --sequence-token "49542672486831074009579604567656788214806863282469607346"

Output:

{
    "nextSequenceToken": "49542672486831074009579604567900991230369019956308219826"
}

Output

nextSequenceToken -> (string)

The next sequence token.

rejectedLogEventsInfo -> (structure)

The rejected events.

tooNewLogEventStartIndex -> (integer)

The log events that are too new.

tooOldLogEventEndIndex -> (integer)

The log events that are dated too far in the past.

expiredLogEventEndIndex -> (integer)

The expired log events.
