get-log-events

Description

Lists log events from the specified log stream. You can list all of the log events or filter using a time range.

By default, this operation returns as many log events as can fit in a response size of 1MB (up to 10,000 log events). You can get additional log events by specifying one of the tokens in a subsequent call. This operation can return empty results while there are more log events available through the token.

If you are using CloudWatch cross-account observability, you can use this operation in a monitoring account and view data from the linked source accounts. For more information, see CloudWatch cross-account observability .

You can specify the log group to search by using either logGroupIdentifier or logGroupName . You must include one of these two parameters, but you can't include both.

Options

--log-group-name (string)

The name of the log group.

Note

You must include either logGroupIdentifier or logGroupName , but not both.

--log-group-identifier (string)

Specify either the name or ARN of the log group to view events from. If the log group is in a source account and you are using a monitoring account, you must use the log group ARN.

Note

You must include either logGroupIdentifier or logGroupName , but not both.

--log-stream-name (string)

The name of the log stream.

--start-time (long)

The start of the time range, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC . Events with a timestamp equal to this time or later than this time are included. Events with a timestamp earlier than this time are not included.

--end-time (long)

The end of the time range, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC . Events with a timestamp equal to or later than this time are not included.

--next-token (string)

The token for the next set of items to return. (You received this token from a previous call.)

--limit (integer)

The maximum number of log events returned. If you don't specify a limit, the default is as many log events as can fit in a response size of 1 MB (up to 10,000 log events).

--start-from-head | --no-start-from-head (boolean)

If the value is true, the earliest log events are returned first. If the value is false, the latest log events are returned first. The default value is false.

If you are using a previous nextForwardToken value as the nextToken in this operation, you must specify true for startFromHead .

--unmask | --no-unmask (boolean)

Specify true to display the log event fields with all sensitive data unmasked and visible. The default is false .

To use this operation with this parameter, you must be signed into an account with the logs:Unmask permission.

--cli-input-json (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI 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.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

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. If automatic pagination is disabled, the AWS CLI will only make one call, for the first page of results.

--output (string)

The formatting style for command output.

  • json
  • text
  • table

--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.

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 retrieves log events from a log stream named 20150601 in the log group my-logs:

aws logs get-log-events --log-group-name my-logs --log-stream-name 20150601

Output:

{
    "nextForwardToken": "f/31961209122447488583055879464742346735121166569214640130",
