You can now monitor your Amazon Kinesis Data Analytics application using the new Amazon CloudWatch KPU-usage metric, which shows you the number of Kinesis Processing Units (KPU) consumed by your application. KPU is a unit of stream processing capacity comprised of 4 GB memory, 1 vCPU compute, and corresponding networking capabilities. The KPU-usage metric makes it easier for you to monitor increases and decreases in your application’s resource usage as the service elastically scales the number of KPUs required to perform your analysis.
