Amazon CloudWatch Logs 2014-03-28
- Client: Aws\CloudWatchLogs\CloudWatchLogsClient
- Service ID: logs
- Version: 2014-03-28
This page describes the parameters and results for the operations of the Amazon CloudWatch Logs (2014-03-28), and shows how to use the Aws\CloudWatchLogs\CloudWatchLogsClient object to call the described operations. This documentation is specific to the 2014-03-28 API version of the service.
Operation Summary
Each of the following operations can be created from a client using
$client->getCommand('CommandName'), where "CommandName" is the
name of one of the following operations. Note: a command is a value that
encapsulates an operation and the parameters used to create an HTTP request.
You can also create and send a command immediately using the magic methods
available on a client object: $client->commandName(/* parameters */).
You can send the command asynchronously (returning a promise) by appending the
word "Async" to the operation name: $client->commandNameAsync(/* parameters */).

Paginators
Paginators handle automatically iterating over paginated API results. Paginators are associated with specific API operations, and they accept the parameters that the corresponding API operation accepts. You can get a paginator from a client class using getPaginator($paginatorName, $operationParameters). This client supports the following paginators:
Operations
AssociateKmsKey
$result = $client->associateKmsKey([/* ... */]); $promise = $client->associateKmsKeyAsync([/* ... */]);
Associates the specified AWS Key Management Service (AWS KMS) customer master key (CMK) with the specified log group.
Associating an AWS KMS CMK with a log group overrides any existing associations between the log group and a CMK. After a CMK is associated with a log group, all newly ingested data for the log group is encrypted using the CMK. This association is stored as long as the data encrypted with the CMK is still within Amazon CloudWatch Logs. This enables Amazon CloudWatch Logs to decrypt this data whenever it is requested.
Note that it can take up to 5 minutes for this operation to take effect.
If you attempt to associate a CMK with a log group but the CMK does not exist or the CMK is disabled, you will receive an InvalidParameterException error.
Parameter Syntax
$result = $client->associateKmsKey([
'kmsKeyId' => '<string>', // REQUIRED
'logGroupName' => '<string>', // REQUIRED
]);
Parameter Details
Members
- kmsKeyId
-
- Type: string
The Amazon Resource Name (ARN) of the CMK to use when encrypting log data. For more information, see Amazon Resource Names - AWS Key Management Service (AWS KMS).

CreateExportTask
$result = $client->createExportTask([/* ... */]); $promise = $client->createExportTaskAsync([/* ... */]);
Creates an export task, which allows you to efficiently export data from a log group to an Amazon S3 bucket.
This is an asynchronous call. If all the required information is provided, this operation initiates an export task and responds with the ID of the task. After the task has started, you can use DescribeExportTasks to get the status of the export task. Each account can only have one active (RUNNING or PENDING) export task at a time. To cancel an export task, use CancelExportTask.
You can export logs from multiple log groups or multiple time ranges to the same S3 bucket. To separate out log data for each export task, you can specify a prefix to be used as the Amazon S3 key prefix for all exported objects.
Parameter Syntax
$result = $client->createExportTask([
'destination' => '<string>', // REQUIRED
'destinationPrefix' => '<string>',
'from' => <integer>, // REQUIRED
'logGroupName' => '<string>', // REQUIRED
'logStreamNamePrefix' => '<string>',
'taskName' => '<string>',
'to' => <integer>, // REQUIRED
]);
Parameter Details
Members
- destination
-
- Type: string
The name of S3 bucket for the exported log data. The bucket must be in the same AWS region.

- logGroupName
-
- Type: string
The name of the log group.
- logStreamNamePrefix
-
- Type: string
Export only log streams that match the provided prefix. If you don't specify a value, no prefix filter is applied.

CreateLogGroup
$result = $client->createLogGroup([/* ... */]); $promise = $client->createLogGroupAsync([/* ... */]);
Creates a log group with the specified name.
You can create up to 5000 log groups per account.
You must use the following guidelines when naming a log group:
-
Log group names must be unique within a region for an AWS account.

Log group names can be between 1 and 512 characters long.
-
Log group names consist of the following characters: a-z, A-Z, 0-9, '_' (underscore), '-' (hyphen), '/' (forward slash), and '.' (period).
If you associate a AWS Key Management Service (AWS KMS) customer master key (CMK) with the log group, ingested data is encrypted using the CMK. This association is stored as long as the data encrypted with the CMK is still within Amazon CloudWatch Logs. This enables Amazon CloudWatch Logs to decrypt this data whenever it is requested.
If you attempt to associate a CMK with the log group but the CMK does not exist or the CMK is disabled, you will receive an InvalidParameterException error.

DisassociateKmsKey
$result = $client->disassociateKmsKey([/* ... */]); $promise = $client->disassociateKmsKeyAsync([/* ... */]);
Disassociates the associated AWS Key Management Service (AWS KMS) customer master key (CMK) from the specified log group.
After the AWS KMS CMK is disassociated from the log group, AWS CloudWatch Logs stops encrypting newly ingested data for the log group. All previously ingested data remains encrypted, and AWS CloudWatch Logs requires permissions for the CMK whenever the encrypted data is requested.
Note that it can take up to 5 minutes for this operation to take effect.

PutDestination
$result = $client->putDestination([/* ... */]); $promise = $client->putDestinationAsync([/* ... */]);
Creates or updates a destination. A destination encapsulates a physical resource (such as an Amazon Kinesis stream) and enables you to subscribe to a real-time stream of log events for a different account, ingested using PutLogEvents. Currently, the only supported physical resource is a Kinesis stream belonging to the same account as the destination.
Through an access policy, a destination controls what is written to its Kinesis stream. By default, PutDestination does not set any access policy with the destination, which means a cross-account user cannot call PutSubscriptionFilter against this destination. To enable this, the destination owner must call PutDestinationPolicy after PutDestination.
Parameter Syntax
$result = $client->putDestination([
'destinationName' => '<string>', // REQUIRED
'roleArn' => '<string>', // REQUIRED
'targetArn' => '<string>', // REQUIRED
]);
Parameter Details
Members
- destinationName

PutLogEvents
$result = $client->putLogEvents([/* ... */]); $promise = $client->putLogEventsAsync([/* ... */]);
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 using DescribeLogStreams. If you call PutLogEvents twice within a narrow time period using the same value for sequenceToken, both calls may be successful, or one may be rejected.
The batch of events must satisfy the following constraints:
-
The maximum batch size is 1,048,576 bytes, and 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 older than 14 days or the retention period of the log group.
-
The log events in the batch must be in chronological ordered by their time stamp. The time stamp is the time the event occurred, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC. (In AWS Tools for PowerShell and the AWS SDK for .NET, the timestamp is specified in .NET format: yyyy-mm-ddThh:mm:ss. For example, 2017-09-15T13:45:30.)
-
The maximum number of log events in a batch is 10,000.
-
A batch of log events in a single request cannot span more than 24 hours. Otherwise, the operation fails.
If a call to PutLogEvents returns "UnrecognizedClientException" the most likely cause is an invalid AWS access key ID or secret key.
