CloudWatchLogs

Service object for interacting with AWS CloudWatchLogs service.

public struct CloudWatchLogs: AWSService

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

Methods

associateKmsKey(_:logger:on:)

@discardableResult public func associateKmsKey(_ input: AssociateKmsKeyRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

Associates the specified AWS Key Management Service (AWS KMS) customer master key (CMK) with the specified log group.

Associating an AWS 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 Amazon CloudWatch Logs. This enables Amazon 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.

cancelExportTask(_:logger:on:)

@discardableResult public func cancelExportTask(_ input: CancelExportTaskRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

Cancels the specified export task.

The task must be in the PENDING or RUNNING state.

createExportTask(_:logger:on:)

public func createExportTask(_ input: CreateExportTaskRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<CreateExportTaskResponse>

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.

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.

Exporting to S3 buckets that are encrypted with AES-256 is supported. Exporting to S3 buckets encrypted with SSE-KMS is not supported.

createLogGroup(_:logger:on:)

@discardableResult public func createLogGroup(_ input: CreateLogGroupRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

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 AWS 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 AWS Key Management Service (AWS KMS) 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 Amazon CloudWatch Logs. This enables Amazon 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.

createLogStream(_:logger:on:)

@discardableResult public func createLogStream(_ input: CreateLogStreamRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

Creates a log stream for the specified log group. A log stream is a sequence of log events that originate from a single source, such as an application instance or a resource that is being monitored.

There is no limit on the number of log streams that you can create for a log group. There is a limit of 50 TPS on CreateLogStream operations, after which transactions are throttled.

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.

deleteDestination(_:logger:on:)

@discardableResult public func deleteDestination(_ input: DeleteDestinationRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

public func deleteQueryDefinition(_ input: DeleteQueryDefinitionRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DeleteQueryDefinitionResponse>

Deletes a saved CloudWatch Logs Insights query definition. A query definition contains details about a saved CloudWatch Logs Insights query.

Each DeleteQueryDefinition operation can delete one query definition.

You must have the logs:DeleteQueryDefinition permission to be able to perform this operation.

deleteResourcePolicy(_:logger:on:)

@discardableResult public func deleteResourcePolicy(_ input: DeleteResourcePolicyRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

Deletes a resource policy from this account. This revokes the access of the identities in that policy to put log events to this account.

deleteRetentionPolicy(_:logger:on:)

@discardableResult public func deleteRetentionPolicy(_ input: DeleteRetentionPolicyRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

Deletes the specified retention policy.

Log events do not expire if they belong to log groups without a retention policy.

@discardableResult public func deleteSubscriptionFilter(_ input: DeleteSubscriptionFilterRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

Deletes the specified subscription filter.

describeDestinations(_:logger:on:)

public func describeDestinations(_ input: DescribeDestinationsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeDestinationsResponse>

Lists all your destinations. The results are ASCII-sorted by destination name.

describeExportTasks(_:logger:on:)

public func describeExportTasks(_ input: DescribeExportTasksRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeExportTasksResponse>

Lists the specified export tasks. You can list all your export tasks or filter the results based on task ID or task status.

public func describeLogGroups(_ input: DescribeLogGroupsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeLogGroupsResponse>

Lists the specified log groups. You can list all your log groups or filter the results by prefix. The results are ASCII-sorted by log group name.

describeLogStreams(_:logger:on:)

public func describeLogStreams(_ input: DescribeLogStreamsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeLogStreamsResponse>

Lists the log streams for the specified log group. You can list all the log streams or filter the results by prefix. You can also control how the results are ordered.

This operation has a limit of five transactions per second, after which transactions are throttled.

describeMetricFilters(_:logger:on:)

public func describeMetricFilters(_ input: DescribeMetricFiltersRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeMetricFiltersResponse>

Lists the specified metric filters. You can list all of the metric filters or filter the results by log name, prefix, metric name, or metric namespace. The results are ASCII-sorted by filter name.

describeQueries(_:logger:on:)

public func describeQueries(_ input: DescribeQueriesRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeQueriesResponse>

Returns a list of CloudWatch Logs Insights queries that are scheduled, executing, or have been executed recently in this account. You can request all queries or limit it to queries of a specific log group or queries with a certain status.

describeQueryDefinitions(_:logger:on:)

public func describeQueryDefinitions(_ input: DescribeQueryDefinitionsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeQueryDefinitionsResponse>

This operation returns a paginated list of your saved CloudWatch Logs Insights query definitions.

You can use the queryDefinitionNamePrefix parameter to limit the results to only the query definitions that have names that start with a certain string.

describeResourcePolicies(_:logger:on:)

public func describeResourcePolicies(_ input: DescribeResourcePoliciesRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeResourcePoliciesResponse>

Lists the resource policies in this account.

describeSubscriptionFilters(_:logger:on:)

public func describeSubscriptionFilters(_ input: DescribeSubscriptionFiltersRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<DescribeSubscriptionFiltersResponse>

disassociateKmsKey(_:logger:on:)

@discardableResult public func disassociateKmsKey(_ input: DisassociateKmsKeyRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

Disassociates the associated AWS Key Management Service (AWS KMS) customer master key (CMK) from the specified log group.

After the AWS KMS CMK is disassociated from the log group, AWS CloudWatch Logs stops encrypting newly ingested data for the log group. All previously ingested data remains encrypted, and AWS CloudWatch Logs requires permissions for the CMK whenever the encrypted data is requested.

Note that it can take up to 5 minutes for this operation to take effect.

filterLogEvents(_:logger:on:)

public func filterLogEvents(_ input: FilterLogEventsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<FilterLogEventsResponse>

Lists log events from the specified log group. You can list all the log events or filter the results using a filter pattern, a time range, and the name of the log stream.

By default, this operation returns as many log events as can fit in 1 MB (up to 10,000 log events) or all the events found within the time range that you specify. If the results include a token, then there are more log events available, and you can get additional results by specifying the token in a subsequent call. This operation can return empty results while there are more log events available through the token.

The returned log events are sorted by event timestamp, the timestamp when the event was ingested by CloudWatch Logs, and the ID of the PutLogEvents request.

getLogEvents(_:logger:on:)

public func getLogEvents(_ input: GetLogEventsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<GetLogEventsResponse>

Lists log events from the specified log stream. You can list all of the log events or filter using a time range.

By default, this operation returns as many log events as can fit in a response size of 1MB (up to 10,000 log events). You can get additional log events by specifying one of the tokens in a subsequent call. This operation can return empty results while there are more log events available through the token.

getLogGroupFields(_:logger:on:)

public func getLogGroupFields(_ input: GetLogGroupFieldsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<GetLogGroupFieldsResponse>

Returns a list of the fields that are included in log events in the specified log group, along with the percentage of log events that contain each field. The search is limited to a time period that you specify.

In the results, fields that start with @ are fields generated by CloudWatch Logs. For example, @timestamp is the timestamp of each log event. For more information about the fields that are generated by CloudWatch logs, see Supported Logs and Discovered Fields.

The response results are sorted by the frequency percentage, starting with the highest percentage.

getLogRecord(_:logger:on:)

public func getLogRecord(_ input: GetLogRecordRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<GetLogRecordResponse>

Retrieves all of the fields and values of a single log event. All fields are retrieved, even if the original query that produced the logRecordPointer retrieved only a subset of fields. Fields are returned as field name/field value pairs.

The full unparsed log event is returned within @message.

getQueryResults(_:logger:on:)

public func getQueryResults(_ input: GetQueryResultsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<GetQueryResultsResponse>

Returns the results from the specified query.

Only the fields requested in the query are returned, along with a @ptr field, which is the identifier for the log record. You can use the value of @ptr in a GetLogRecord operation to get the full log record.

GetQueryResults does not start a query execution. To run a query, use StartQuery.

If the value of the Status field in the output is Running, this operation returns only partial results. If you see a value of Scheduled or Running for the status, you can retry the operation later to see the final results.

listTagsLogGroup(_:logger:on:)

public func listTagsLogGroup(_ input: ListTagsLogGroupRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<ListTagsLogGroupResponse>

Lists the tags for the specified log group.

putDestination(_:logger:on:)

public func putDestination(_ input: PutDestinationRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<PutDestinationResponse>

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.

putDestinationPolicy(_:logger:on:)

@discardableResult public func putDestinationPolicy(_ input: PutDestinationPolicyRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

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 AWS 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.

putLogEvents(_:logger:on:)

public func putLogEvents(_ input: PutLogEventsRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<PutLogEventsResponse>

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 AWS Tools for PowerShell and the AWS 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 AWS access key ID or secret key.

putMetricFilter(_:logger:on:)

@discardableResult public func putMetricFilter(_ input: PutMetricFilterRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

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 AWS Charges.

putQueryDefinition(_:logger:on:)

public func putQueryDefinition(_ input: PutQueryDefinitionRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<PutQueryDefinitionResponse>

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.

putResourcePolicy(_:logger:on:)

public func putResourcePolicy(_ input: PutResourcePolicyRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<PutResourcePolicyResponse>

Creates or updates a resource policy allowing other AWS services to put log events to this account, such as Amazon Route 53. An account can have up to 10 resource policies per AWS Region.

putRetentionPolicy(_:logger:on:)

@discardableResult public func putRetentionPolicy(_ input: PutRetentionPolicyRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

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

putSubscriptionFilter(_:logger:on:)

@discardableResult public func putSubscriptionFilter(_ input: PutSubscriptionFilterRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

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 AWS 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.

startQuery(_:logger:on:)

public func startQuery(_ input: StartQueryRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<StartQueryResponse>

Schedules a query of a log group using CloudWatch Logs Insights. You specify the log group and time range to query and the query string to use.

For more information, see CloudWatch Logs Insights Query Syntax.

Queries time out after 15 minutes of execution. If your queries are timing out, reduce the time range being searched or partition your query into a number of queries.

stopQuery(_:logger:on:)

public func stopQuery(_ input: StopQueryRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<StopQueryResponse>

Stops a CloudWatch Logs Insights query that is in progress. If the query has already ended, the operation returns an error indicating that the specified query is not running.

tagLogGroup(_:logger:on:)

@discardableResult public func tagLogGroup(_ input: TagLogGroupRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

Adds or updates the specified tags for the specified log group.

To list the tags for a log group, use ListTagsLogGroup. To remove tags, use UntagLogGroup.

For more information about tags, see Tag Log Groups in Amazon CloudWatch Logs in the Amazon CloudWatch Logs User Guide.

testMetricFilter(_:logger:on:)

public func testMetricFilter(_ input: TestMetricFilterRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<TestMetricFilterResponse>

Tests the filter pattern of a metric filter against a sample of log event messages. You can use this operation to validate the correctness of a metric filter pattern.

untagLogGroup(_:logger:on:)

@discardableResult public func untagLogGroup(_ input: UntagLogGroupRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil) -> EventLoopFuture<Void>

Removes the specified tags from the specified log group.

To list the tags for a log group, use ListTagsLogGroup. To add tags, use TagLogGroup.

describeDestinationsPaginator(_:_:logger:on:onPage:)

public func describeDestinationsPaginator<Result>(_ input: DescribeDestinationsRequest, _ initialValue: Result, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil, onPage: @escaping (Result, DescribeDestinationsResponse, EventLoop) -> EventLoopFuture<(Bool, Result)>) -> EventLoopFuture<Result>

public func describeMetricFiltersPaginator<Result>(_ input: DescribeMetricFiltersRequest, _ initialValue: Result, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil, onPage: @escaping (Result, DescribeMetricFiltersResponse, EventLoop) -> EventLoopFuture<(Bool, Result)>) -> EventLoopFuture<Result>

Lists the specified metric filters. You can list all of the metric filters or filter the results by log name, prefix, metric name, or metric namespace. The results are ASCII-sorted by filter name.

Provide paginated results to closure onPage for it to combine them into one result. This works in a similar manner to Array.reduce<Result>(_:_:) -> Result.

Parameters:

  • input: Input for request
  • initialValue: The value to use as the initial accumulating value. initialValue is passed to onPage the first time it is called.
  • logger: Logger used for logging output
  • eventLoop: EventLoop to run this process on
  • onPage: closure called with each paginated response. It combines an accumulating result with the contents of response. This combined result is then returned along with a boolean indicating if the paginate operation should continue.

describeMetricFiltersPaginator(_:logger:on:onPage:)

Provide paginated results to closure onPage.

public func describeMetricFiltersPaginator(_ input: DescribeMetricFiltersRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil, onPage: @escaping (DescribeMetricFiltersResponse, EventLoop) -> EventLoopFuture<Bool>) -> EventLoopFuture<Void>

Parameters

  • input: Input for request
  • logger: Logger used for logging output
  • eventLoop: EventLoop to run this process on
  • onPage: closure called with each block of entries. Returns boolean indicating whether we should continue.

describeSubscriptionFiltersPaginator(_:_:logger:on:onPage:)

public func describeSubscriptionFiltersPaginator<Result>(_ input: DescribeSubscriptionFiltersRequest, _ initialValue: Result, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil, onPage: @escaping (Result, DescribeSubscriptionFiltersResponse, EventLoop) -> EventLoopFuture<(Bool, Result)>) -> EventLoopFuture<Result>

Lists the subscription filters for the specified log group. You can list all the subscription filters or filter the results by prefix. The results are ASCII-sorted by filter name.

Provide paginated results to closure onPage for it to combine them into one result. This works in a similar manner to Array.reduce<Result>(_:_:) -> Result.

Parameters:

  • input: Input for request
  • initialValue: The value to use as the initial accumulating value. initialValue is passed to onPage the first time it is called.
  • logger: Logger used for logging output
  • eventLoop: EventLoop to run this process on
  • onPage: closure called with each paginated response. It combines an accumulating result with the contents of response. This combined result is then returned along with a boolean indicating if the paginate operation should continue.

describeSubscriptionFiltersPaginator(_:logger:on:onPage:)

Provide paginated results to closure onPage.

public func describeSubscriptionFiltersPaginator(_ input: DescribeSubscriptionFiltersRequest, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil, onPage: @escaping (DescribeSubscriptionFiltersResponse, EventLoop) -> EventLoopFuture<Bool>) -> EventLoopFuture<Void>

Parameters

  • input: Input for request
  • logger: Logger used for logging output
  • eventLoop: EventLoop to run this process on
  • onPage: closure called with each block of entries. Returns boolean indicating whether we should continue.

filterLogEventsPaginator(_:_:logger:on:onPage:)

public func filterLogEventsPaginator<Result>(_ input: FilterLogEventsRequest, _ initialValue: Result, logger: Logger = AWSClient.loggingDisabled, on eventLoop: EventLoop? = nil, onPage: @escaping (Result, FilterLogEventsResponse, EventLoop) -> EventLoopFuture<(Bool, Result)>) -> EventLoopFuture<Result>

Lists log events from the specified log group. You can list all the log events or filter the results using a filter pattern, a time range, and the name of the log stream.

By default, this operation returns as many log events as can fit in 1 MB (up to 10,000 log events) or all the events found within the time range that you specify. If the results include a token, then there are more log events available, and you can get additional results by specifying the token in a subsequent call. This operation can return empty results while there are more log events available through the token.

The returned log events are sorted by event timestamp, the timestamp when the event was ingested by CloudWatch Logs, and the ID of the PutLogEvents request.

Provide paginated results to closure onPage for it to combine them into one result. This works in a similar manner to Array.reduce<Result>(_:_:) -> Result.

Parameters:

  • input: Input for request
  • initialValue: The value to use as the initial accumulating value. initialValue is passed to onPage the first time it is called.
  • logger: Logger used for logging output
  • eventLoop: EventLoop to run this process on
  • onPage: closure called with each paginated response. It combines an accumulating result with the contents of response. This combined result is then returned along with a boolean indicating if the paginate operation should continue.

filterLogEventsPaginator(_:logger:on:onPage:)

Parameters

  • input: Input for request
  • logger: Logger used for logging output
  • eventLoop: EventLoop to run this process on
  • onPage: closure called with each block of entries. Returns boolean indicating whether we should continue.

getLogEventsPaginator(_:_:logger:on:onPage:)
