describe-log-groups

Description

Lists the specified log groups. You can list all your log groups or filter the results by prefix. The results are ASCII-sorted by log group name.

CloudWatch Logs doesn’t support IAM policies that control access to the DescribeLogGroups action by using the ``aws:ResourceTag/key-name `` condition key. Other CloudWatch Logs actions do support the use of the ``aws:ResourceTag/key-name `` condition key to control access. For more information about using tags to control access, see Controlling access to Amazon Web Services resources using tags .

See ‘aws help’ for descriptions of global parameters.

describe-log-groups is a paginated operation. Multiple API calls may be issued in order to retrieve the entire data set of results. You can disable pagination by providing the --no-paginate argument. When using --output text and the --query argument on a paginated response, the --query argument must extract data from the results of the following query expressions: logGroups

Synopsis

  describe-log-groups
[--log-group-name-prefix <value>]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

Options

--log-group-name-prefix (string)

The prefix to match.

--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.

--starting-token (string)

A token to specify where to start paginating. This is the NextToken from a previously truncated response.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--page-size (integer)

The size of each page to get in the AWS service call. This does not affect the number of items returned in the command’s output. Setting a smaller page size results in more calls to the AWS service, retrieving fewer items in each call. This can help prevent the AWS service calls from timing out.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--max-items (integer)

The total number of items to return in the command’s output. If the total number of items available is more than the value specified, a NextToken is provided in the command’s output. To resume pagination, provide the NextToken value in the starting-token argument of a subsequent command. Do not use the NextToken response element directly outside of the AWS CLI.

For usage examples, see Pagination in the AWS Command Line Interface User Guide .

--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.

See ‘aws help’ for descriptions of global parameters.

Examples

The following command describes a log group named my-logs:

aws logs describe-log-groups --log-group-name-prefix my-logs

Output:

{
    "logGroups": [
        {
            "storedBytes": 0,
            "metricFilterCount": 0,
            "creationTime": 1433189500783,
            "logGroupName": "my-logs",
            "retentionInDays": 5,
            "arn": "arn:aws:logs:us-west-2:0123456789012:log-group:my-logs:*"
        }
    ]
}

Output

logGroups -> (list)

The log groups.

If the retentionInDays value if not included for a log group, then that log group is set to have its events never expire.

(structure)

Represents a log group.

logGroupName -> (string)

The name of the log group.

creationTime -> (long)

The creation time of the log group, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC.

retentionInDays -> (integer)

The number of days to retain the log events in the specified log group. Possible values are: 1, 3, 5, 7, 14, 30, 60, 90, 120, 150, 180, 365, 400, 545, 731, 1827, and 3653.

To set a log group to never have log events expire, use DeleteRetentionPolicy .

metricFilterCount -> (integer)

The number of metric filters.

arn -> (string)

The Amazon Resource Name (ARN) of the log group.

storedBytes -> (long)

The number of bytes stored.

kmsKeyId -> (string)

The Amazon Resource Name (ARN) of the CMK to use when encrypting log data.

nextToken -> (string)

The token for the next set of items to return. The token expires after 24 hours.
