Overview

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

You can use CloudWatch Logs to:

  • Monitor Logs from Amazon EC2 Instances in Real-time: You can use CloudWatch Logs to monitor applications and systems using log data. For example, CloudWatch Logs can track the number of errors that occur in your application logs and send you a notification whenever the rate of errors exceeds a threshold you specify. CloudWatch Logs uses your log data for monitoring; so, no code changes are required. For example, you can monitor application logs for specific literal terms (such as "NullReferenceException") or count the number of occurrences of a literal term at a particular position in log data (such as "404" status codes in an Apache access log). When the term you are searching for is found, CloudWatch Logs reports the data to a Amazon CloudWatch metric that you specify.

  • Monitor Amazon CloudTrail Logged Events: You can create alarms in Amazon CloudWatch and receive notifications of particular API activity as captured by CloudTrail and use the notification to perform troubleshooting.

  • Archive Log Data: You can use CloudWatch Logs to store your log data in highly durable storage. You can change the log retention setting so that any log events older than this setting are automatically deleted. The CloudWatch Logs agent makes it easy to quickly send both rotated and non-rotated log data off of a host and into the log service. You can then access the raw log data when you need it.

  configuration

The service configuration used to instantiate this service client.

@property (nonatomic, strong, readonly) AWSServiceConfiguration *configuration

Discussion

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

Declared In

AWSLogsService.h

+ defaultLogs

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.

+ (instancetype)defaultLogs

Return Value

The default service client.

Discussion

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];

     [AWSLogs registerLogsWithConfiguration:configuration forKey:@"USWest2Logs"];

     return YES;

– putDestination:

Creates or updates a destination. A destination encapsulates a physical resource (such as a Kinesis stream) and enables you to subscribe to a real-time stream of log events of a different account, ingested using PutLogEvents. Currently, the only supported physical resource is a Amazon Kinesis stream belonging to the same account as the destination.

A destination controls what is written to its Amazon Kinesis stream through an access policy. By default, PutDestination does not set any access policy with the destination, which means a cross-account user cannot call PutSubscriptionFilter against this destination. To enable this, the destination owner must call PutDestinationPolicy after PutDestination.

- (AWSTask<AWSLogsPutDestinationResponse*> *)putDestination:(AWSLogsPutDestinationRequest *)request

Parameters

request

Return Value

An instance of AWSTask. On successful execution, task.result will contain an instance of AWSLogsPutDestinationResponse.

– putLogEvents:

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 using DescribeLogStreams.

  • The maximum batch size is 1,048,576 bytes, and this size is calculated as the sum of all event messages in UTF-8, plus 26 bytes for each log event.

  • None of the log events in the batch can be more than 2 hours in the future.

  • None of the log events in the batch can be older than 14 days or the retention period of the log group.

  • The log events in the batch must be in chronological ordered by their timestamp (the time the event occurred, expressed as the number of milliseconds since Jan 1, 1970 00:00:00 UTC).

  • The maximum number of log events in a batch is 10,000.
