    Amazon CloudWatch Logs Service API Reference
    This is the Amazon CloudWatch Logs API Reference . Amazon
    CloudWatch Logs is a managed service for real time monitoring and
    archival of application logs. This guide provides detailed
    information about Amazon CloudWatch Logs actions, data types,
    parameters, and errors. For detailed information about Amazon
    CloudWatch Logs features and their associated API calls, go to the
    `Amazon CloudWatch Logs Developer Guide`_.

Use the following links to get started using the Amazon CloudWatch
    API Reference :

+ `Actions`_: An alphabetical list of all Amazon CloudWatch Logs
      actions.
    + `Data Types`_: An alphabetical list of all Amazon CloudWatch
      Logs data types.
    + `Common Parameters`_: Parameters that all Query actions can use.
    + `Common Errors`_: Client and server errors that all actions can
      return.
    + `Regions and Endpoints`_: Itemized regions and endpoints for all
      AWS products.

In addition to using the Amazon CloudWatch Logs API, you can also
    use the following SDKs and third-party libraries to access Amazon
    CloudWatch Logs programmatically.

+ `AWS SDK for Java Documentation`_
    + `AWS SDK for .NET Documentation`_
    + `AWS SDK for PHP Documentation`_
    + `AWS SDK for Ruby Documentation`_

Developers in the AWS developer community also provide their own
    libraries, which you can find at the following AWS developer
    centers:

+ `AWS Java Developer Center`_
    + `AWS PHP Developer Center`_
    + `AWS Python Developer Center`_
