      • setEndpoint

        public void setEndpoint​(String endpoint)
        Description copied from interface: AWSLogs
        Overrides the default endpoint for this client ("https://logs.us-east-1.amazonaws.com"). Callers can use this method to control which AWS region they want to work with.

        Callers can pass in just the endpoint (ex: "logs.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://logs.us-east-1.amazonaws.com"). If the protocol is not specified here, the default protocol from this client's ClientConfiguration will be used, which by default is HTTPS.

        For more information on using AWS regions with the AWS SDK for Java, and a complete list of all available endpoints for all AWS services, see: http://developer.amazonwebservices.com/connect/entry.jspa?externalID= 3912

        This method is not threadsafe. An endpoint should be configured when the client is created and before any service requests are made. Changing it afterwards creates inevitable race conditions for any service requests in transit or retrying.

        Specified by:
        setEndpoint in interface AWSLogs
        Parameters:
        endpoint - The endpoint (ex: "logs.us-east-1.amazonaws.com") or a full URL, including the protocol (ex: "https://logs.us-east-1.amazonaws.com") of the region specific AWS endpoint this client will communicate with.
      • createExportTask

        public CreateExportTaskResult createExportTask​(CreateExportTaskRequest request)
        Description copied from interface: AWSLogs

        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. You can only have one active ( RUNNING or PENDING) export task at a time, per account.

        You can export logs from multiple log groups or multiple time ranges to the same Amazon S3 bucket. To separate out log data for each export task, you can specify a prefix that will be used as the Amazon S3 key prefix for all exported objects.

        Specified by:
        createExportTask in interface AWSLogs
        Returns:
        Result of the CreateExportTask operation returned by the service.

      • putDestination

        public PutDestinationResult putDestination​(PutDestinationRequest request)
        Description copied from interface: AWSLogs

        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.

        Specified by:
        putDestination in interface AWSLogs
        Returns:
        Result of the PutDestination operation returned by the service.
      • putLogEvents

        public PutLogEventsResult putLogEvents​(PutLogEventsRequest request)
        Description copied from interface: AWSLogs

        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.
        • The maximum number of log events in a batch is 10,000.
        • A batch of log events in a single PutLogEvents request cannot span more than 24 hours. Otherwise, the PutLogEvents operation will fail.

        Specified by:
        putLogEvents in interface AWSLogs
        Returns:
        Result of the PutLogEvents operation returned by the service.
      • putMetricFilter

        public PutMetricFilterResult putMetricFilter​(PutMetricFilterRequest request)
        Description copied from interface: AWSLogs

        Creates or updates a metric filter and associates it with the specified log group. Metric filters allow you to configure rules to extract metric data from log events ingested through PutLogEvents requests.

        The maximum number of metric filters that can be associated with a log group is 100.

        Specified by:
        putMetricFilter in interface AWSLogs
        Returns:
        Result of the PutMetricFilter operation returned by the service.
      • putRetentionPolicy

        public PutRetentionPolicyResult putRetentionPolicy​(PutRetentionPolicyRequest request)
        Description copied from interface: AWSLogs

        Sets the retention of the specified log group. A retention policy allows you to configure the number of days you want to retain log events in the specified log group.

        Specified by:
        putRetentionPolicy in interface AWSLogs
        Returns:
        Result of the PutRetentionPolicy operation returned by the service.
      • putSubscriptionFilter

        public PutSubscriptionFilterResult putSubscriptionFilter​(PutSubscriptionFilterRequest request)
        Description copied from interface: AWSLogs

        Creates or updates a subscription filter and associates it with the specified log group. Subscription filters allow you to subscribe to a real-time stream of log events ingested through PutLogEvents requests and have them delivered to a specific destination. Currently, the supported destinations are:

        • An Amazon Kinesis stream belonging to the same account as the subscription filter, for same-account delivery.
        • A logical destination (used via an ARN of Destination) belonging to a different account, for cross-account delivery.
        • An Amazon Kinesis Firehose stream belonging to the same account as the subscription filter, for same-account delivery.
        • An AWS Lambda function belonging to the same account as the subscription filter, for same-account delivery.

        Currently there can only be one subscription filter associated with a log group.

        Specified by:
        putSubscriptionFilter in interface AWSLogs
        Returns:
        Result of the PutSubscriptionFilter operation returned by the service.

        Specified by:
        testMetricFilter in interface AWSLogs
        Returns:
        Result of the TestMetricFilter operation returned by the service.
      • shutdown

        public void shutdown()
        Description copied from interface: AWSLogs
        Shuts down this client object, releasing any resources that might be held open. This is an optional method, and callers are not expected to call it, but can if they want to explicitly release any open resources. Once a client has been shutdown, it should not be used to make any more requests.
        Specified by:
        shutdown in interface AWSLogs
      • getCachedResponseMetadata

        public ResponseMetadata getCachedResponseMetadata​(AmazonWebServiceRequest request)
        Description copied from interface: AWSLogs
        Returns additional metadata for a previously executed successful request, typically used for debugging issues where a service isn't acting as expected. This data isn't considered part of the result data returned by an operation, so it's available through this separate, diagnostic interface.

        Response metadata is only cached for a limited period of time, so if you need to access this extra diagnostic information for an executed request, you should use this method to retrieve it as soon as possible after executing a request.

        Specified by:
        getCachedResponseMetadata in interface AWSLogs
        Parameters:
        request - The originally executed request.
        Returns:
        The response metadata for the specified request, or null if none is available.
