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 .
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 .

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
describe-log-groups
[--account-identifiers <value>]
[--log-group-name-prefix <value>]
[--log-group-name-pattern <value>]
[--include-linked-accounts | --no-include-linked-accounts]
[--cli-input-json | --cli-input-yaml]
[--starting-token <value>]
[--page-size <value>]
[--max-items <value>]
[--generate-cli-skeleton <value>]

--account-identifiers
(list)
When
includeLinkedAccounts
is set toTrue
, use this parameter to specify the list of accounts to search. You can specify as many as 20 account IDs in the array.(string)
Syntax:
"string" "string" ...
--log-group-name-prefix
(string)
The prefix to match.
Note
logGroupNamePrefix
andlogGroupNamePattern
are mutually exclusive. Only one of these parameters can be passed.
--log-group-name-pattern
(string)If you specify a string for this parameter, the operation returns only log groups that have names that match the string based on a case-sensitive substring search. For example, if you specify
Foo
, log groups namedFooBar
,aws/Foo
, andGroupFoo
would match, butfoo
,F/o/o
andFroo
would not match.Note
logGroupNamePattern
andlogGroupNamePrefix
are mutually exclusive. Only one of these parameters can be passed.
--include-linked-accounts
|--no-include-linked-accounts
(boolean)If you are using a monitoring account, set this to
True
to have the operation return log groups in the accounts listed inaccountIdentifiers
.If this parameter is set to
true
andaccountIdentifiers
contains a null value, the operation returns all log groups in the monitoring account and all log groups in all source accounts that are linked to the monitoring account.Note
If you specify
includeLinkedAccounts
in your request, thenmetricFilterCount
,retentionInDays
, andstoredBytes
are not included in the response.
--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 theNextToken
value in thestarting-token
argument of a subsequent command. Do not use theNextToken
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 valueinput
, prints a sample input JSON that can be used as an argument for--cli-input-json
. Similarly, if providedyaml-input
it will print a sample input YAML that can be used with--cli-input-yaml
. If provided with the valueoutput
, 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 thecli-binary-format
setting. When usingfile://
the file contents will need to properly formatted for the configuredcli-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 describes a log group named
my-logs
:aws logs describe-log-groups --log-group-name-prefix my-logsOutput:
