Interface for accessing CloudWatchLogs
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.

CreateDelivery(CreateDeliveryRequest) |
Creates a delivery. A delivery is a connection between a logical delivery source and a logical delivery destination that you have already created. Only some Amazon Web Services services support being configured as a delivery source using this operation. These services are listed as Supported [V2 Permissions] in the table at Enabling logging from Amazon Web Services services. A delivery destination can represent a log group in CloudWatch Logs, an Amazon S3 bucket, or a delivery stream in Firehose. To configure logs delivery between a supported Amazon Web Services service and a destination, you must do the following:
You can configure a single delivery source to send logs to multiple destinations by creating multiple deliveries. You can also create multiple deliveries to configure multiple delivery sources to send logs to the same delivery destination. You can't update an existing delivery. You can only create and delete deliveries. |

CreateExportTask(CreateExportTaskRequest) |
Creates an export task so that you can efficiently export data from a log group to
an Amazon S3 bucket. When you perform a 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 ( 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. |

CreateLogAnomalyDetector(CreateLogAnomalyDetectorRequest) |
Creates an anomaly detector that regularly scans one or more log groups and look for patterns and anomalies in the logs. An anomaly detector can help surface issues by automatically discovering anomalies in your log event traffic. An anomaly detector uses machine learning algorithms to scan log events and find patterns. A pattern is a shared text structure that recurs among your log fields. Patterns provide a useful tool for analyzing large sets of logs because a large number of log events can often be compressed into a few patterns.
The anomaly detector uses pattern recognition to find
Fields within a pattern are called tokens. Fields that vary within a pattern,
such as a request ID or timestamp, are referred to as dynamic tokens and represented
by The following is an example of a pattern:
This pattern represents log events like Any parts of log events that are masked as sensitive data are not scanned for anomalies. For more information about masking sensitive data, see Help protect sensitive log data with masking. |

CreateLogGroup(CreateLogGroupRequest) |
Creates a log group with the specified name. You can create up to 1,000,000 log groups per Region per account. You must use the following guidelines when naming a log group:

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 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. |

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 CloudWatch Logs might disable a metric filter if it generates 1,000 different name/value pairs for your specified dimensions within one hour. 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. |

PutRetentionPolicy(PutRetentionPolicyRequest) |
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.
When log events reach their retention setting they are marked for deletion. After
they are marked for deletion, they do not add to your archival storage costs anymore,
even if they are not actually deleted until later. These log events marked for deletion
are also not included when you use an API to retrieve the |

The following objects are sent over the stream:
You can end a session before it times out by closing the session stream or by closing the client that is receiving the stream.
