createExportTask( array $args = array() )

Executes the CreateExportTask operation.

Creates an ExportTask which allows you to efficiently export data from a Log Group to your Amazon S3 bucket.

This is an asynchronous call. If all the required information is provided, this API will initiate an export task and respond with the task Id. Once started, DescribeExportTasks can be used to get the status of an export task.

Examples

$result = $client->createExportTask(array(
    'taskName' => 'string',
    // logGroupName is required
    'logGroupName' => 'string',
    'logStreamNamePrefix' => 'string',
    // from is required
    'from' => integer,
    // to is required

logStreamNamePrefix => (string)

Will only export log streams that match the provided logStreamNamePrefix. If you don't specify a value, no prefix filter is applied.
from => (int)

A unix timestamp indicating the start time of the range for the request. Events with a timestamp prior to this time will not be exported.
to => (int)

destination => (string)

Name of Amazon S3 bucket to which the log data will be exported.
NOTE: Only buckets in the same AWS region are supported
destinationPrefix => (string)

Prefix that will be used as the start of Amazon S3 key for every object exported. If not specified, this defaults to 'exportedlogs'.

filterLogEvents( array $args = array() )

Executes the FilterLogEvents operation.

Retrieves log events, optionally filtered by a filter pattern from the specified log group. You can provide an optional time range to filter the results on the event timestamp. You can limit the streams searched to an explicit list of logStreamNames.

By default, this operation returns as much matching log events as can fit in a response size of 1MB, up to 10,000 log events, or all the events found within a time-bounded scan window. If the response includes a nextToken, then there is more data to search, and the search can be resumed with a new request providing the nextToken. The response will contain a list of searchedLogStreams that contains information about which streams were searched in the request and whether they have been searched completely or require further pagination. The limit parameter in the request. can be used to specify the maximum number of events to return in a page.

Examples

putDestination( array $args = array() )

Executes the PutDestination operation.

Creates or updates a Destination . A destination encapsulates a physical resource (such as a Kinesis stream) and allows you to subscribe to a real-time stream of log events of a different account, ingested through PutLogEvents requests. Currently, the only supported physical resource is a Amazon Kinesis stream belonging to the same account as the destination.

A destination controls what is written to its Amazon Kinesis stream through an access policy. By default, PutDestination does not set any access policy with the destination, which means a cross-account user will not be able to call PutSubscriptionFilter against this destination. To enable that, the destination owner must call PutDestinationPolicy after PutDestination.

Examples

Basic formatting example

$result = $client->putDestination(array(
    // destinationName is required
    'destinationName' => 'string',
    // targetArn is required
    'targetArn' => 'string',
    // roleArn is required
    'roleArn' => 'string',

The ARN of an IAM role that grants Amazon CloudWatch Logs permissions to do Amazon Kinesis PutRecord requests on the desitnation stream.

Returns

Guzzle\Service\Resource\Model
Returns a response Model object

destination => (associative-array)

A cross account destination that is the recipient of subscription log events.
- destinationName => (string)
  
  Name of the destination.
- targetArn => (string)
  
  ARN of the physical target where the log events will be delivered (eg. ARN of a Kinesis stream).

putLogEvents( array $args = array() )

Executes the PutLogEvents operation.

Uploads a batch of log events to the specified log stream.

Every PutLogEvents request must include the sequenceToken obtained from the response of the previous request. An upload in a newly created log stream does not require a sequenceToken.

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 timestamp.
