New Features

CloudWatch Custom Application Metrics You can publish your own metrics to Amazon CloudWatch with the mon-put-data command or the PutMetricData action. You can also retrieve statistics, view graphs, or create alarms for your published metrics.

Other Changes

CloudWatch Alarm History Retention Amazon CloudWatch now retains the history of an alarm for two weeks rather than six weeks. With this change, the retention period for alarms matches the retention period for metrics data.
SOAP Not Supported The PutMetricData action does not support the Simple Object Access Protocol (SOAP).

Known Issues

Data Type Attribute Name Difference The MetricAlarm data type contains an attribute named InsufficientDataActions. The current WSDL, however, refers to this attribute as UnknownActions. If you use the Query API, expect the MetricAlarm data type to have an attribute named UnknownActions instead of InsufficientDataActions.
