Client for accessing Amazon CloudWatch Logs. All service calls made using this client are blocking, and will not return until the service call completes.

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. Alternatively, you can use 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. Then, it can 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"). You can also 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 earlier than this setting are automatically deleted. The CloudWatch Logs agent helps 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 static AWSLogsClientBuilder builder()
```
  - associateKmsKey
```
public AssociateKmsKeyResult associateKmsKey(AssociateKmsKeyRequest request)
```
    Associates the specified KMS key with the specified log group.
    
    Associating a KMS key with a log group overrides any existing associations between the log group and a KMS key. After a KMS key is associated with a log group, all newly ingested data for the log group is encrypted using the KMS key. This association is stored as long as the data encrypted with the KMS keyis still within CloudWatch Logs. This enables CloudWatch Logs to decrypt this data whenever it is requested.
    
    CloudWatch Logs supports only symmetric KMS keys. Do not use an associate an asymmetric KMS key 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 KMS key with a log group but the KMS key does not exist or the KMS key is disabled, you receive an InvalidParameterException error.
    
    Specified by:
    
    associateKmsKey in interface AWSLogs
    
    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
```
public CancelExportTaskResult cancelExportTask(CancelExportTaskRequest request)
```
    Cancels the specified export task.
    
    The task must be in the PENDING or RUNNING state.
    
    Specified by:
    
    cancelExportTask in interface AWSLogs
    
    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.

  - createExportTask
```
public CreateExportTaskResult createExportTask(CreateExportTaskRequest request)
```
    Creates an export task so that you can 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 S3 buckets that are encrypted by KMS is supported. Exporting log data to Amazon S3 buckets that have S3 Object Lock enabled with a retention period is also 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 log data for each export task, 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 field data by using Linux utilities.
    
    Specified by:
    
    createExportTask in interface AWSLogs
    
    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.

  - createLogGroup
```
public CreateLogGroupResult createLogGroup(CreateLogGroupRequest request)
```
    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 do not expire. To set a retention policy so that events expire and are deleted after a specified time, use PutRetentionPolicy.
    
    If you associate an KMS key with the log group, ingested data is encrypted using the KMS key. This association is stored as long as the data encrypted with the KMS key is still within CloudWatch Logs. This enables CloudWatch Logs to decrypt this data whenever it is requested.
    
    If you attempt to associate a KMS key with the log group but the KMS keydoes not exist or the KMS key is disabled, you receive an InvalidParameterException error.
    
    CloudWatch Logs supports only symmetric KMS keys. Do not associate an asymmetric KMS key with your log group. For more information, see Using Symmetric and Asymmetric Keys.

  - putDataProtectionPolicy
```
public PutDataProtectionPolicyResult putDataProtectionPolicy(PutDataProtectionPolicyRequest request)
```
    Creates a data protection policy for the specified log group. A data protection policy can help safeguard sensitive data that's ingested by the log group by auditing and masking the sensitive log data.
    
    Sensitive data is detected and masked when it is ingested into the log group. When you set a data protection policy, log events ingested into the log group before that time are not masked.
    
    By default, when a user views a log event that includes masked data, the sensitive data is replaced by asterisks. A user who has the logs:Unmask permission can use a GetLogEvents or FilterLogEvents operation with the unmask parameter set to true to view the unmasked log events. Users with the logs:Unmask can also view unmasked data in the CloudWatch Logs console by running a CloudWatch Logs Insights query with the unmask query command.
    
    For more information, including a list of types of data that can be audited and masked, see Protect sensitive log data with masking.

  - putDestination
```
public PutDestinationResult putDestination(PutDestinationRequest request)
```
    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). With a destination, you can 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.
    
    Specified by:
    
    putDestination in interface AWSLogs
    
    Parameters:
    
    putDestinationRequest -
    
    Returns:
    
    Result of the PutDestination operation returned by the service.

    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.

  - putLogEvents
```
public PutLogEventsResult putLogEvents(PutLogEventsRequest request)
```
    Uploads a batch of log events to the specified log stream.
    
    The sequence token is now ignored in PutLogEvents actions. PutLogEvents actions are always accepted and never return InvalidSequenceTokenException or DataAlreadyAcceptedException even if the sequence token is not valid. You can use parallel PutLogEvents actions on the same log stream.
    
    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 more than 14 days in the past. Also, none of the log events can be from earlier 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 that 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.
    - The quota of five requests per second per log stream has been removed. Instead, PutLogEvents actions are throttled based on a per-second per-account quota. You can request an increase to the per-second throttling quota by using the Service Quotas service.
    If a call to PutLogEvents returns "UnrecognizedClientException" the most likely cause is a non-valid Amazon Web Services access key ID or secret key.
    Specified by:
    
    putLogEvents in interface AWSLogs
    
    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.
    
    PutLogEvents actions are now always accepted and never return InvalidSequenceTokenException regardless of receiving an invalid sequence token.
    
    DataAlreadyAcceptedException - The event was already logged.
    
    PutLogEvents actions are now always accepted and never return DataAlreadyAcceptedException regardless of whether a given batch of log events has already been accepted.
    
    ResourceNotFoundException - The specified resource does not exist.
    
    ServiceUnavailableException - The service cannot complete the request.
    
    UnrecognizedClientException - The most likely cause is an Amazon Web Services access key ID or secret key that's not valid.

  - putMetricFilter
```
public PutMetricFilterResult putMetricFilter(PutMetricFilterRequest request)
```
    Creates or updates a metric filter and associates it with the specified log group. With metric filters, you can 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.
    
    CloudWatch Logs disables a metric filter if it generates 1,000 different name/value pairs for your specified dimensions within a certain amount of time. This helps to prevent accidental high charges.
    
    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.

  - putQueryDefinition
```
public PutQueryDefinitionResult putQueryDefinition(PutQueryDefinitionRequest request)
```
    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, imagine updating a current query definition that includes log groups. If 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.
    
    Specified by:
    
    putQueryDefinition in interface AWSLogs
    
    Parameters:
    
    putQueryDefinitionRequest -
    
    Returns:
    
    Result of the PutQueryDefinition 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.

  - putResourcePolicy
```
public PutResourcePolicyResult putResourcePolicy(PutResourcePolicyRequest request)
```
    Creates or updates a resource policy allowing other Amazon Web Services services to put log events to this account, such as Amazon Route 53. An account can have up to 10 resource policies per Amazon Web Services Region.
    
    Specified by:
    
    putResourcePolicy in interface AWSLogs
    
    Parameters:
    
    putResourcePolicyRequest -
    
    Returns:
    
    Result of the PutResourcePolicy 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.
    
    ServiceUnavailableException - The service cannot complete the request.

  - putRetentionPolicy
```
public PutRetentionPolicyResult putRetentionPolicy(PutRetentionPolicyRequest request)
```
    Sets the retention of the specified log group. With a retention policy, you can configure the number of days for which to retain log events in the specified log group.
    
    CloudWatch Logs doesn’t immediately delete log events when they reach their retention setting. It typically takes up to 72 hours after that before log events are deleted, but in rare situations might take longer.
    
    To illustrate, imagine that you change a log group to have a longer retention setting when it contains log events that are past the expiration date, but haven’t been deleted. Those log events will take up to 72 hours to be deleted after the new retention date is reached. To make sure that log data is deleted permanently, keep a log group at its lower retention setting until 72 hours after the previous retention period ends. Alternatively, wait to change the retention setting until you confirm that the earlier log events are deleted.
    
    Specified by:
    
    putRetentionPolicy in interface AWSLogs
    
    Parameters:
    
    putRetentionPolicyRequest -
    
    Returns:
    
    Result of the PutRetentionPolicy 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.

  - putSubscriptionFilter
```
public PutSubscriptionFilterResult putSubscriptionFilter(PutSubscriptionFilterRequest request)
```
    Creates or updates a subscription filter and associates it with the specified log group. With subscription filters, you can 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 data 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 Data 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.
    Specified by:
    
    putSubscriptionFilter in interface AWSLogs
    
    Parameters:
    
    putSubscriptionFilterRequest -
    
    Returns:
    
    Result of the PutSubscriptionFilter operation returned by the service.
    
    Throws:
    
    InvalidParameterException - A parameter is specified incorrectly.
    
    ResourceNotFoundException - The specified resource does not exist.

  - tagLogGroup
```
@Deprecated
public TagLogGroupResult tagLogGroup(TagLogGroupRequest request)
```
    Deprecated.
    
    The TagLogGroup operation is on the path to deprecation. We recommend that you use TagResource instead.
    
    Adds or updates the specified tags for the specified log group.
    
    To list the tags for a log group, use ListTagsForResource. To remove tags, use UntagResource.
    
    For more information about tags, see Tag Log Groups in Amazon CloudWatch Logs in the Amazon CloudWatch Logs User Guide.
    
    CloudWatch Logs doesn’t support IAM policies that prevent users from assigning specified tags to log groups using the aws:Resource/key-name or aws:TagKeys condition keys. For more information about using tags to control access, see Controlling access to Amazon Web Services resources using tags.
    
    Specified by:
    
    tagLogGroup in interface AWSLogs
    
    Parameters:
    
    tagLogGroupRequest -
    
    Returns:
    
    Result of the TagLogGroup operation returned by the service.
    
    Throws:

  - tagResource
```
public TagResourceResult tagResource(TagResourceRequest request)
```
    Assigns one or more tags (key-value pairs) to the specified CloudWatch Logs resource. Currently, the only CloudWatch Logs resources that can be tagged are log groups and destinations.
    
    Tags can help you organize and categorize your resources. You can also use them to scope user permissions by granting a user permission to access or change only resources with certain tag values.
    
    Tags don't have any semantic meaning to Amazon Web Services and are interpreted strictly as strings of characters.
    
    You can use the TagResource action with a resource that already has tags. If you specify a new tag key for the alarm, this tag is appended to the list of tags associated with the alarm. If you specify a tag key that is already associated with the alarm, the new tag value that you specify replaces the previous value for that tag.
    
    You can associate as many as 50 tags with a CloudWatch Logs resource.
    
    Specified by:
    
    tagResource in interface AWSLogs
    
    Parameters:
    
    tagResourceRequest -
    
    Returns:
    
    Result of the TagResource operation returned by the service.
    
    Throws:
    
    InvalidParameterException - A parameter is specified incorrectly.
    
    ResourceNotFoundException - The specified resource does not exist.
    
    ServiceUnavailableException - The service cannot complete the request.
    
    TooManyTagsException - A resource can have no more than 50 tags.

  - getCachedResponseMetadata
```
public 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 the 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.
