@ThreadSafe public class AWSLogsClient extends AmazonWebServiceClient implements AWSLogs
Client for accessing Amazon CloudWatch Logs. All service calls made using this client are blocking, and will not return until the service call completes.Amazon CloudWatch Logs API Reference You can use Amazon CloudWatch Logs to monitor, store, and access your log files from Amazon Elastic Compute Cloud (Amazon EC2) instances, Amazon CloudTrail, or other sources. You can then retrieve the associated log data from CloudWatch Logs using the Amazon CloudWatch console, the CloudWatch Logs commands in the AWS CLI, the CloudWatch Logs API, or the CloudWatch Logs SDK.
You can use CloudWatch Logs to:
-
Monitor Logs from Amazon EC2 Instances in Real-time: You can use CloudWatch Logs to monitor applications and systems using log data. For example, CloudWatch Logs can track the number of errors that occur in your application logs and send you a notification whenever the rate of errors exceeds a threshold you specify. CloudWatch Logs uses your log data for monitoring; so, no code changes are required. For example, you can monitor application logs for specific literal terms (such as "NullReferenceException") or count the number of occurrences of a literal term at a particular position in log data (such as "404" status codes in an Apache access log). When the term you are searching for is found, CloudWatch Logs reports the data to a Amazon CloudWatch metric that you specify.
-
Monitor Amazon CloudTrail Logged Events: You can create alarms in Amazon CloudWatch and receive notifications of particular API activity as captured by CloudTrail and use the notification to perform troubleshooting.
-
Archive Log Data: You can use CloudWatch Logs to store your log data in highly durable storage. You can change the log retention setting so that any log events older than this setting are automatically deleted. The CloudWatch Logs agent makes it easy to quickly send both rotated and non-rotated log data off of a host and into the log service. You can then access the raw log data when you need it.

public PutDestinationResult putDestination(PutDestinationRequest putDestinationRequest)
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 throughPutLogEvents
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 callPutDestinationPolicy
after PutDestination.- Specified by:

-- Returns:
- Result of the PutDestinationPolicy operation returned by the service.
- Throws:
InvalidParameterException

- Returned if multiple requests to update the same resource were in conflict.ServiceUnavailableException
- Returned if the service cannot complete the request.
-
putLogEvents
public PutLogEventsResult putLogEvents(PutLogEventsRequest putLogEventsRequest)
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 asequenceToken
.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.
