public interface AWSLogs
```
Interface for accessing Amazon CloudWatch Logs.
Note: Do not directly implement this interface, new methods are added to it regularly. Extend from AbstractAWSLogs instead.

You can use Amazon CloudWatch Logs to monitor, store, and access your log files from EC2 instances, CloudTrail, and other sources. You can then retrieve the associated log data from CloudWatch Logs using the CloudWatch console, CloudWatch Logs commands in the Amazon Web Services CLI, CloudWatch Logs API, or CloudWatch Logs SDK.

You can use CloudWatch Logs to:
- Monitor logs from 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 that 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 CloudWatch metric that you specify.
- Monitor CloudTrail logged events: You can create alarms in CloudWatch and receive notifications of particular API activity as captured by CloudTrail. You can 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.

  - setEndpoint
```
@Deprecated
void setEndpoint(String endpoint)
```
    Deprecated. use AwsClientBuilder#setEndpointConfiguration(AwsClientBuilder.EndpointConfiguration) for example: builder.setEndpointConfiguration(new EndpointConfiguration(endpoint, signingRegion));
    
    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: https://docs.aws.amazon.com/sdk-for-java/v1/developer-guide/java-dg-region-selection.html#region-selection- choose-endpoint
    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.
    
    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.
  - setRegion
```
@Deprecated
void setRegion(Region region)
```
    Deprecated. use AwsClientBuilder#setRegion(String)
    
    An alternative to setEndpoint(String), sets the regional endpoint for this client's service calls. Callers can use this method to control which AWS region they want to work with.
    By default, all service endpoints in all regions use the https protocol. To use http instead, specify it in the ClientConfiguration supplied at construction.
    This method is not threadsafe. A region 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.
    
    Parameters:
    
    region - The region this client will communicate with. See Region.getRegion(com.amazonaws.regions.Regions) for accessing a given region. Must not be null and must be a region where the service is available.

  - associateKmsKey
```
AssociateKmsKeyResult associateKmsKey(AssociateKmsKeyRequest associateKmsKeyRequest)
```
    Associates the specified Key Management Service customer master key (CMK) with the specified log group.
    
    Associating an 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 CloudWatch Logs. This enables CloudWatch Logs to decrypt this data whenever it is requested.
    
    CloudWatch Logs supports only symmetric CMKs. Do not use an associate an asymmetric CMK with your log group. For more information, see Using Symmetric and Asymmetric Keys.
    
    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 receive an InvalidParameterException error.
    
    Parameters:
    
    associateKmsKeyRequest -
    
    Returns:
    
    Result of the AssociateKmsKey operation returned by the service.
    
    Throws:
    
    InvalidParameterException - A parameter is specified incorrectly.
    
    ResourceNotFoundException - The specified resource does not exist.
    
    OperationAbortedException - Multiple concurrent requests to update the same resource were in conflict.
    
    ServiceUnavailableException - The service cannot complete the request.

  - cancelExportTask
```
CancelExportTaskResult cancelExportTask(CancelExportTaskRequest cancelExportTaskRequest)
```
    Cancels the specified export task.
    
    The task must be in the PENDING or RUNNING state.
    
    Parameters:
    
    cancelExportTaskRequest -
    
    Returns:
    
    Result of the CancelExportTask operation returned by the service.
    
    Throws:
    
    InvalidParameterException - A parameter is specified incorrectly.
    
    ResourceNotFoundException - The specified resource does not exist.
    
    InvalidOperationException - The operation is not valid on the specified resource.
    
    ServiceUnavailableException - The service cannot complete the request.

    AWS API Documentation
  - createExportTask
```
CreateExportTaskResult createExportTask(CreateExportTaskRequest createExportTaskRequest)
```
    Creates an export task, which allows you to efficiently export data from a log group to an Amazon S3 bucket. When you perform a CreateExportTask operation, you must use credentials that have permission to write to the S3 bucket that you specify as the destination.
    
    Exporting log data to Amazon S3 buckets that are encrypted by KMS is not supported. Exporting log data to Amazon S3 buckets that have S3 Object Lock enabled with a retention period is not supported.
    
    Exporting to S3 buckets that are encrypted with AES-256 is supported.
    
    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.
    
    Time-based sorting on chunks of log data inside an exported file is not guaranteed. You can sort the exported log fild data by using Linux utilities.
    
    Parameters:
    
    createExportTaskRequest -
    
    Returns:
    
    Result of the CreateExportTask operation returned by the service.
    
    Throws:
    
    InvalidParameterException - A parameter is specified incorrectly.
    
    LimitExceededException - You have reached the maximum number of resources that can be created.
    
    OperationAbortedException - Multiple concurrent requests to update the same resource were in conflict.
    
    ServiceUnavailableException - The service cannot complete the request.
    
    ResourceNotFoundException - The specified resource does not exist.
    
    ResourceAlreadyExistsException - The specified resource already exists.

    AWS API Documentation
  - createLogGroup
```
CreateLogGroupResult createLogGroup(CreateLogGroupRequest createLogGroupRequest)
```
    Creates a log group with the specified name. You can create up to 20,000 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 Amazon Web Services 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), '.' (period), and '#' (number sign)
    When you create a log group, by default the log events in the log group never expire. To set a retention policy so that events expire and are deleted after a specified time, use PutRetentionPolicy.
    
    If you associate a Key Management Service 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 CloudWatch Logs. This enables 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 receive an InvalidParameterException error.
    
    CloudWatch Logs supports only symmetric CMKs. Do not associate an asymmetric CMK with your log group. For more information, see Using Symmetric and Asymmetric Keys.
    Parameters:
    
    createLogGroupRequest -
    
    Returns:
    
    Result of the CreateLogGroup operation returned by the service.
    
    Throws:
    
    InvalidParameterException - A parameter is specified incorrectly.
    
    ResourceAlreadyExistsException - The specified resource already exists.
    
    LimitExceededException - You have reached the maximum number of resources that can be created.
    
    OperationAbortedException - Multiple concurrent requests to update the same resource were in conflict.
    
    ServiceUnavailableException - The service cannot complete the request.

    You must use the following guidelines when naming a log stream:
    - Log stream names must be unique within the log group.
    - Log stream names can be between 1 and 512 characters long.
    - The ':' (colon) and '*' (asterisk) characters are not allowed.
    Parameters:
    
    createLogStreamRequest -
    
    Returns:
    
    Result of the CreateLogStream operation returned by the service.

  - putDestination
```
PutDestinationResult putDestination(PutDestinationRequest putDestinationRequest)
```
    Creates or updates a destination. This operation is used only to create destinations for cross-account subscriptions.
    
    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.
    
    Through an access policy, a destination controls what is written to it. 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.
    
    To perform a PutDestination operation, you must also have the iam:PassRole permission.
    
    Parameters:
    
    putDestinationRequest -
    
    Returns:
    
    Result of the PutDestination operation returned by the service.
    
    Throws:
    
    InvalidParameterException - A parameter is specified incorrectly.
    
    OperationAbortedException - Multiple concurrent requests to update the same resource were in conflict.
    
    ServiceUnavailableException - The service cannot complete the request.
    
    See Also:
    
    AWS API Documentation
  - putDestinationPolicy
```
PutDestinationPolicyResult putDestinationPolicy(PutDestinationPolicyRequest putDestinationPolicyRequest)
```
    Creates or updates an access policy associated with an existing destination. An access policy is an IAM policy document that is used to authorize claims to register a subscription filter against a given destination.
    
    If multiple Amazon Web Services accounts are sending logs to this destination, each sender account must be listed separately in the policy. The policy does not support specifying * as the Principal or the use of the aws:PrincipalOrgId global key.
    
    Parameters:
    
    putDestinationPolicyRequest -
    
    Returns:
    
    Result of the PutDestinationPolicy operation returned by the service.
    
    Throws:
    
    InvalidParameterException - A parameter is specified incorrectly.
    
    OperationAbortedException - Multiple concurrent requests to update the same resource were in conflict.
    
    ServiceUnavailableException - The service cannot complete the request.

    AWS API Documentation
  - putLogEvents
```
PutLogEventsResult putLogEvents(PutLogEventsRequest putLogEventsRequest)
```
    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 in the expectedSequenceToken field from InvalidSequenceTokenException. If you call PutLogEvents twice within a narrow time period using the same value for sequenceToken, both calls might be successful or one might be rejected.
    
    The batch of events must satisfy the following constraints:
    - The maximum batch size is 1,048,576 bytes. 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 older than the retention period of the log group.
    - The log events in the batch must be in chronological order by their timestamp. The timestamp is the time the event occurred, expressed as the number of milliseconds after Jan 1, 1970 00:00:00 UTC. (In Amazon Web Services Tools for PowerShell and the Amazon Web Services SDK for .NET, the timestamp is specified in .NET format: yyyy-mm-ddThh:mm:ss. For example, 2017-09-15T13:45:30.)
    - A batch of log events in a single request cannot span more than 24 hours. Otherwise, the operation fails.
    - The maximum number of log events in a batch is 10,000.
    - There is a quota of 5 requests per second per log stream. Additional requests are throttled. This quota can't be changed.
    If a call to PutLogEvents returns "UnrecognizedClientException" the most likely cause is an invalid Amazon Web Services access key ID or secret key.
    Parameters:
    
    putLogEventsRequest -
    
    Returns:
    
    Result of the PutLogEvents operation returned by the service.
    
    Throws:
    
    InvalidParameterException - A parameter is specified incorrectly.
    
    InvalidSequenceTokenException - The sequence token is not valid. You can get the correct sequence token in the expectedSequenceToken field in the InvalidSequenceTokenException message.
    
    DataAlreadyAcceptedException - The event was already logged.
    
    ResourceNotFoundException - The specified resource does not exist.
    
    ServiceUnavailableException - The service cannot complete the request.
    
    UnrecognizedClientException - The most likely cause is an invalid Amazon Web Services access key ID or secret key.

  - putMetricFilter
```
PutMetricFilterResult putMetricFilter(PutMetricFilterRequest putMetricFilterRequest)
```
    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.
    
    The maximum number of metric filters that can be associated with a log group is 100.
    
    When you create a metric filter, you can also optionally assign a unit and dimensions to the metric that is created.
    
    Metrics extracted from log events are charged as custom metrics. To prevent unexpected high charges, do not specify high-cardinality fields such as IPAddress or requestID as dimensions. Each different value found for a dimension is treated as a separate metric and accrues charges as a separate custom metric.
    
    To help prevent accidental high charges, Amazon disables a metric filter if it generates 1000 different name/value pairs for the dimensions that you have specified within a certain amount of time.
    
    You can also set up a billing alarm to alert you if your charges are higher than expected. For more information, see Creating a Billing Alarm to Monitor Your Estimated Amazon Web Services Charges.
    
    Parameters:
    
    putMetricFilterRequest -
    
    Returns:
    
    Result of the PutMetricFilter operation returned by the service.
    
    Throws:
    
    InvalidParameterException - A parameter is specified incorrectly.
    
    ResourceNotFoundException - The specified resource does not exist.

  - putQueryDefinition
```
PutQueryDefinitionResult putQueryDefinition(PutQueryDefinitionRequest putQueryDefinitionRequest)
```
    Creates or updates a query definition for CloudWatch Logs Insights. For more information, see Analyzing Log Data with CloudWatch Logs Insights.
    
    To update a query definition, specify its queryDefinitionId in your request. The values of name, queryString, and logGroupNames are changed to the values that you specify in your update operation. No current values are retained from the current query definition. For example, if you update a current query definition that includes log groups, and you don't specify the logGroupNames parameter in your update operation, the query definition changes to contain no log groups.
    
    You must have the logs:PutQueryDefinition permission to be able to perform this operation.
    
    Parameters:
    
    putQueryDefinitionRequest -
    
    Returns:
    
    Result of the PutQueryDefinition operation returned by the service.

  - putSubscriptionFilter
```
PutSubscriptionFilterResult putSubscriptionFilter(PutSubscriptionFilterRequest putSubscriptionFilterRequest)
```
    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 and have them delivered to a specific destination. When log events are sent to the receiving service, they are Base64 encoded and compressed with the gzip format.
    
    The following destinations are supported for subscription filters:
    - An Amazon Kinesis stream belonging to the same account as the subscription filter, for same-account delivery.
    - A logical destination that belongs to a different account, for cross-account delivery.
    - An Amazon Kinesis Firehose delivery stream that belongs to the same account as the subscription filter, for same-account delivery.
    - An Lambda function that belongs to the same account as the subscription filter, for same-account delivery.
    Each log group can have up to two subscription filters associated with it. If you are updating an existing filter, you must specify the correct name in filterName.
    
    To perform a PutSubscriptionFilter operation, you must also have the iam:PassRole permission.

    untagLogGroupRequest -
    
    Returns:
    
    Result of the UntagLogGroup operation returned by the service.

  - shutdown
```
void shutdown()
```
    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.
  - getCachedResponseMetadata
```
ResponseMetadata getCachedResponseMetadata(AmazonWebServiceRequest request)
```
    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.
    
    Parameters:
    
    request - The originally executed request.
    
    Returns:
    
    The response metadata for the specified request, or null if none is available.
