Amazon CloudWatch Logs API Reference
You can use Amazon CloudWatch Logs to monitor, store, and access your log files from Amazon Elastic Compute Cloud (Amazon 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.
Each argument is described in detail in: Paws::CloudWatchLogs::CancelExportTask
Returns: nothing
Cancels an export task if it is in C<PENDING> or C<RUNNING> state.
Each argument is described in detail in: Paws::CloudWatchLogs::CreateExportTask
Returns: a Paws::CloudWatchLogs::CreateExportTaskResponse instance
Creates an C<ExportTask> which allows you to efficiently export data from a Log Group to your Amazon S3 bucket.
This is an asynchronous call. If all the required information is provided, this API will initiate an export task and respond with the task Id. Once started, DescribeExportTasks can be used to get the status of an export task. You can only have one active (RUNNING or PENDING) export task at a time, per account.
DescribeExportTasks
RUNNING
PENDING
You can export logs from multiple log groups or multiple time ranges to the same Amazon S3 bucket. To separate out log data for each export task, you can specify a prefix that will be used as the Amazon S3 key prefix for all exported objects.
Each argument is described in detail in: Paws::CloudWatchLogs::CreateLogGroup
Creates a new log group with the specified name. The name of the log group must be unique within a region for an AWS account. You can create up to 500 log groups per account.
You must use the following guidelines when naming a log group:
Log group names can be between 1 and 512 characters long.
Allowed characters are a-z, A-Z, 0-9, '_' (underscore), '-' (hyphen), '/' (forward slash), and '.' (period).
Each argument is described in detail in: Paws::CloudWatchLogs::CreateLogStream
Creates a new log stream in the specified log group. The name of the log stream must be unique within the log group. There is no limit on the number of log streams that can exist in a log group.

Retrieves log events, optionally filtered by a filter pattern from the specified log group. You can provide an optional time range to filter the results on the event C<timestamp>. You can limit the streams searched to an explicit list of C<logStreamNames>.
By default, this operation returns as much matching log events as can fit in a response size of 1MB, up to 10,000 log events, or all the events found within a time-bounded scan window. If the response includes a nextToken, then there is more data to search, and the search can be resumed with a new request providing the nextToken. The response will contain a list of searchedLogStreams that contains information about which streams were searched in the request and whether they have been searched completely or require further pagination. The limit parameter in the request. can be used to specify the maximum number of events to return in a page.
searchedLogStreams

nextForwardToken
nextBackwardToken
GetLogEvents
Each argument is described in detail in: Paws::CloudWatchLogs::PutDestination
Returns: a Paws::CloudWatchLogs::PutDestinationResponse instance
Creates or updates a C<Destination>. A destination encapsulates a physical resource (such as a Kinesis stream) and allows you to subscribe to a real-time stream of log events of a different account, ingested through C<PutLogEvents> requests. 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 will not be able to call PutSubscriptionFilter against this destination. To enable that, the destination owner must call PutDestinationPolicy after PutDestination.
PutSubscriptionFilter
PutDestinationPolicy
Each argument is described in detail in: Paws::CloudWatchLogs::PutDestinationPolicy
Creates or updates an access policy associated with an existing C<Destination>. An access policy is an IAM policy document that is used to authorize claims to register a subscription filter against a given destination.
Each argument is described in detail in: Paws::CloudWatchLogs::PutLogEvents
Returns: a Paws::CloudWatchLogs::PutLogEventsResponse instance
Uploads a batch of log events to the specified log stream.
Every PutLogEvents request must include the sequenceToken obtained from the response of the previous request. An upload in a newly created log stream does not require a sequenceToken.
sequenceToken
The batch of events must satisfy the following constraints:
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.
timestamp
The maximum number of log events in a batch is 10,000.
A batch of log events in a single PutLogEvents request cannot span more than 24 hours. Otherwise, the PutLogEvents operation will fail.
Each argument is described in detail in: Paws::CloudWatchLogs::PutMetricFilter
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 C<PutLogEvents> requests.
The maximum number of metric filters that can be associated with a log group is 100.
Each argument is described in detail in: Paws::CloudWatchLogs::PutRetentionPolicy
Sets the retention of the specified log group. A retention policy allows you to configure the number of days you want to retain log events in the specified log group.
Each argument is described in detail in: Paws::CloudWatchLogs::PutSubscriptionFilter
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 C<PutLogEvents> requests and have them delivered to a specific destination. Currently, the supported destinations are:
An Amazon Kinesis stream belonging to the same account as the subscription filter, for same-account delivery.
A logical destination (used via an ARN of Destination) belonging to a different account, for cross-account delivery.
Destination
An Amazon Kinesis Firehose stream belonging to the same account as the subscription filter, for same-account delivery.
An AWS Lambda function belonging to the same account as the subscription filter, for same-account delivery.
Currently there can only be one subscription filter associated with a log group.
Each argument is described in detail in: Paws::CloudWatchLogs::TestMetricFilter
Returns: a Paws::CloudWatchLogs::TestMetricFilterResponse instance
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.
