AWSLogs

Objective-C

@interface AWSLogs

Swift

class AWSLogs

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.

  • The service configuration used to instantiate this service client.

    Warning

    Once the client is instantiated, do not modify the configuration object. It may cause unspecified behaviors.

    Declaration

    Objective-C

    @property (nonatomic, strong, readonly) AWSServiceConfiguration *configuration
  • Returns the singleton service client. If the singleton object does not exist, the SDK instantiates the default service client with defaultServiceConfiguration from [AWSServiceManager defaultServiceManager]. The reference to this object is maintained by the SDK, and you do not need to retain it manually.

    For example, set the default service configuration in - application:didFinishLaunchingWithOptions:

    Swift

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
       let credentialProvider = AWSCognitoCredentialsProvider(regionType: .USEast1, identityPoolId: "YourIdentityPoolId")
       let configuration = AWSServiceConfiguration(region: .USEast1, credentialsProvider: credentialProvider)
       AWSServiceManager.default().defaultServiceConfiguration = configuration
    
       return true
    

    }

    Objective-C

    - (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
         AWSCognitoCredentialsProvider *credentialsProvider = [[AWSCognitoCredentialsProvider alloc] initWithRegionType:AWSRegionUSEast1
                                                                                                         identityPoolId:@"YourIdentityPoolId"];
         AWSServiceConfiguration *configuration = [[AWSServiceConfiguration alloc] initWithRegion:AWSRegionUSEast1
                                                                              credentialsProvider:credentialsProvider];
         [AWSServiceManager defaultServiceManager].defaultServiceConfiguration = configuration;
    
         return YES;
     }
    

    Then call the following to get the default service client:

    Swift

    let Logs = AWSLogs.default()
    

    Objective-C

    AWSLogs *Logs = [AWSLogs defaultLogs];
    

    Declaration

    Objective-C

    + (nonnull instancetype)defaultLogs;

    Swift

    class func `default`() -> Self

    Return Value

    The default service client.

  • Creates a service client with the given service configuration and registers it for the key.

    For example, set the default service configuration in - application:didFinishLaunchingWithOptions:

    Swift

    func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

        [AWSLogs registerLogsWithConfiguration:configuration forKey:@"USWest2Logs"];
    
        return YES;
    }
    

    Then call the following to get the service client:

    Swift

    let Logs = AWSLogs(forKey: "USWest2Logs")
    

    Objective-C

    AWSLogs *Logs = [AWSLogs LogsForKey:@"USWest2Logs"];

        [AWSLogs registerLogsWithConfiguration:configuration forKey:@"USWest2Logs"];
    
        return YES;
    }
    

    Then call the following to get the service client:

    Swift

    let Logs = AWSLogs(forKey: "USWest2Logs")
    

    Objective-C

    AWSLogs *Logs = [AWSLogs LogsForKey:@"USWest2Logs"];
    

    Declaration

    Objective-C

    + (nonnull instancetype)LogsForKey:(nonnull NSString *)key;

    Swift

    convenience init(forKey key: String)

    Parameters

    key

    A string to identify the service client.

    Return Value

    An instance of the service client.

  • Removes the service client associated with the key and release it.

    Warning

    Before calling this method, make sure no method is running on this client.

    Declaration

    Objective-C

    + (void)removeLogsForKey:(nonnull NSString *)key;

    Swift

    class func remove(forKey key: String)

    Parameters

    key

    A string to identify the service client.

  • Associates the specified KMS key with either one log group in the account, or with all stored CloudWatch Logs query insights results in the account.

    When you use AssociateKmsKey, you specify either the logGroupName parameter or the resourceIdentifier parameter. You can’t specify both of those parameters in the same operation.

    • Specify the logGroupName parameter to cause all log events stored in the log group to be encrypted with that key. Only the log events ingested after the key is associated are encrypted with that key.

      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 key is still within CloudWatch Logs. This enables CloudWatch Logs to decrypt this data whenever it is requested.

      Associating a key with a log group does not cause the results of queries of that log group to be encrypted with that key. To have query results encrypted with a KMS key, you must use an AssociateKmsKey operation with the resourceIdentifier parameter that specifies a query-result resource.

    • Specify the resourceIdentifier parameter with a query-result resource, to use that key to encrypt the stored results of all future StartQuery operations in the account. The response from a GetQueryResults operation will still return the query results in plain text.

      Even if you have not associated a key with your query results, the query results are encrypted when stored, using the default CloudWatch Logs method.

      If you run a query from a monitoring account that queries logs in a source account, the query results key from the monitoring account, if any, is used.

    If you delete the key that is used to encrypt log events or log group query results, then all the associated stored log events or query results that were encrypted with that key will be unencryptable and unusable.

    CloudWatch Logs supports only symmetric KMS keys. Do not use an associate an asymmetric KMS key with your log group or query results. 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.

  • 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.

  • 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 key does not exist or the KMS key is disabled, you receive an InvalidParameterException error.

  • Disassociates the specified KMS key from the specified log group or from all CloudWatch Logs Insights query results in the account.

    When you use DisassociateKmsKey, you specify either the logGroupName parameter or the resourceIdentifier parameter. You can’t specify both of those parameters in the same operation.

    • Specify the logGroupName parameter to stop using the KMS key to encrypt future log events ingested and stored in the log group. Instead, they will be encrypted with the default CloudWatch Logs method. The log events that were ingested while the key was associated with the log group are still encrypted with that key. Therefore, CloudWatch Logs will need permissions for the key whenever that data is accessed.

    • Specify the resourceIdentifier parameter with the query-result resource to stop using the KMS key to encrypt the results of all future StartQuery operations in the account. They will instead be encrypted with the default CloudWatch Logs method. The results from queries that ran while the key was associated with the account are still encrypted with that key. Therefore, CloudWatch Logs will need permissions for the key whenever that data is accessed.

    It can take up to 5 minutes for this operation to take effect.

  • 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.

    You must have the logs:FilterLogEvents permission to perform this operation.

    You can specify the log group to search by using either logGroupIdentifier or logGroupName. You must include one of these two parameters, but you can’t include both.

    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 specified time range. If the results include a token, that means there are more log events available. 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.

  • Creates an account-level data protection policy that applies to all log groups in the account. A data protection policy can help safeguard sensitive data that’s ingested by your log groups by auditing and masking the sensitive log data. Each account can have only one account-level policy.

    Sensitive data is detected and masked when it is ingested into a log group. When you set a data protection policy, log events ingested into the log groups before that time are not masked.

    If you use PutAccountPolicy to create a data protection policy for your whole account, it applies to both existing log groups and all log groups that are created later in this account. The account policy is applied to existing log groups with eventual consistency. It might take up to 5 minutes before sensitive data in existing log groups begins to be 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.

    To use the PutAccountPolicy operation, you must be signed on with the logs:PutDataProtectionPolicy and logs:PutAccountPolicy permissions.

    The PutAccountPolicy operation applies to all log groups in the account. You can also use PutDataProtectionPolicy to create a data protection policy that applies to just one log group. If a log group has its own data protection policy and the account also has an account-level data protection policy, then the two policies are cumulative. Any sensitive term specified in either policy is masked.

  • 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.

  • 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.

    • Each log event can be no larger than 256 KB.

    • 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.

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.

    • Each log event can be no larger than 256 KB.

    • 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.

    Parameters

    request

    A container for the necessary parameters to execute the PutLogEvents service method.

    completionHandler

    The completion handler to call when the load request is complete. response - A response object, or nil if the request failed. error - An error object that indicates why the request failed, or nil if the request was successful. On failed execution, error may contain an NSError with AWSLogsErrorDomain domain and the following error code: AWSLogsErrorInvalidParameter, AWSLogsErrorInvalidSequenceToken, AWSLogsErrorDataAlreadyAccepted, AWSLogsErrorResourceNotFound, AWSLogsErrorServiceUnavailable, AWSLogsErrorUnrecognizedClient.

  • 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.

  • 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.

  • 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 created with PutDestination that belongs to a different account, for cross-account delivery. We currently support Kinesis Data Streams and Kinesis Data Firehose as logical destinations.

    • 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 for any destination except a Lambda function, you must also have the iam:PassRole permission.

  • 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.

    After you run a query using StartQuery, the query results are stored by CloudWatch Logs. You can use GetQueryResults to retrieve the results of a query, using the queryId that StartQuery returns.

    If you have associated a KMS key with the query results in this account, then StartQuery uses that key to encrypt the results when it stores them. If no key is associated with query results, the query results are encrypted with the default CloudWatch Logs encryption method.

    Queries time out after 60 minutes of runtime. If your queries are timing out, reduce the time range being searched or partition your query into a number of queries.

    If you are using CloudWatch cross-account observability, you can use this operation in a monitoring account to start a query in a linked source account. For more information, see CloudWatch cross-account observability. For a cross-account StartQuery operation, the query definition must be defined in the monitoring account.

    You can have up to 30 concurrent CloudWatch Logs insights queries, including queries that have been added to dashboards.

  • 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.
