API for Amazon CloudWatch¶

ABAP Package	`/AWS1/API_CWT_IMPL`
ABAP SDK "TLA"	`CWT`
ABAP Interface	`/AWS1/IF_CWT`

The "TLA" is a Three Letter Abbreviation that appears in ABAP class names, data dictionary objects and other ABAP objects throughout the AWS SDK for SAP ABAP. The TLA for Amazon CloudWatch is CWT. This TLA helps squeeze ABAP objects into the 30-character length limit of the ABAP data dictionary.

Installation¶

To install the AWS SDK for SAP ABAP, import the Core transport, along with the transport for the CloudWatch module and other API modules you are interested in. A few modules are included in the Core transport itself. For more information, see the Developer Guide guide.

About The Service¶

Amazon CloudWatch monitors your Amazon Web Services (Amazon Web Services) resources and the applications you run on Amazon Web Services in real time. You can use CloudWatch to collect and track metrics, which are the variables you want to measure for your resources and applications.

CloudWatch alarms send notifications or automatically change the resources you are monitoring based on rules that you define. For example, you can monitor the CPU usage and disk reads and writes of your Amazon EC2 instances. Then, use this data to determine whether you should launch additional instances to handle increased load. You can also use this data to stop under-used instances to save money.

In addition to monitoring the built-in metrics that come with Amazon Web Services, you can monitor your own custom metrics. With CloudWatch, you gain system-wide visibility into resource utilization, application performance, and operational health.

Using the SDK¶

In your code, create a client using the SDK module for Amazon CloudWatch, which is created with factory method /AWS1/CL_CWT_FACTORY=>create(). In this example we will assume you have configured an SDK profile in transaction /AWS1/IMG called ZFINANCE.

DATA(go_session)   = /aws1/cl_rt_session_aws=>create( 'ZFINANCE' ).
DATA(go_cwt)       = /aws1/cl_cwt_factory=>create( go_session ).

Your variable go_cwt is an instance of /AWS1/IF_CWT, and all of the operations in the Amazon CloudWatch service are accessed by calling methods in /AWS1/IF_CWT.

API Operations¶

For an overview of ABAP method calls corresponding to API operations in Amazon CloudWatch, see the Operation List.

Factory Method¶

`/AWS1/CL_CWT_FACTORY=>create( )`¶

Creates an object of type /AWS1/IF_CWT.

IMPORTING¶

Optional arguments:¶

`IV_PROTOCOL` `TYPE /AWS1/RT_PROTOCOL` `/AWS1/RT_PROTOCOL`¶

`IO_SESSION` `TYPE REF TO /AWS1/CL_RT_SESSION_BASE` `/AWS1/CL_RT_SESSION_BASE`¶

`IV_REGION` `TYPE /AWS1/RT_REGION_ID` `/AWS1/RT_REGION_ID`¶

`IV_CUSTOM_ENDPOINT` `TYPE /AWS1/RT_ENDPOINT` `/AWS1/RT_ENDPOINT`¶

RETURNING¶

`OO_CLIENT` `TYPE REF TO /AWS1/IF_CWT` `/AWS1/IF_CWT`¶

/AWS1/IF_CWT represents the ABAP client for the CloudWatch service, representing each operation as a method call. For more information see the API Page page.

Configuring Programmatically¶

DATA(lo_config) = DATA(go_cwt)->get_config( ).

lo_config is a variable of type /AWS1/CL_CWT_CONFIG. See the documentation for /AWS1/CL_CWT_CONFIG for details on the settings that can be configured.

Waiters¶

Waiters for Implementation can be accessed via get_waiter() method followed by the waiter method to be called.

Details about the waiter methods available for service Implementation can be found in interface /AWS1/IF_CWT_WAITER.

Paginators¶

Paginators for Amazon CloudWatch can be created via get_paginator() which returns a paginator object of type /AWS1/IF_CWT_PAGINATOR. The operation method that is being paginated is called using the paginator object, which accepts any necessary parameters to provide to the underlying API operation. This returns an iterator object which can be used to iterate over paginated results using has_next() and get_next() methods.

Details about the paginator methods available for service Amazon CloudWatch can be found in interface /AWS1/IF_CWT_PAGINATOR.
