Measures reported by AWSMSKThrBanTest
The consumer periodically sends a request to a Kafka broker in order to fetch data from it. The consumer application then receives a number of records in a response, processes them and asks for more in the form of another request.
This test monitors each fetch request raised by the consumer and also identifies the average fetch throttle time taken for each request. Using this test, the administrators can rapidly capture real/probable problem conditions during fetch process and swiftly resolve them, so as to ensure the high availability of the target AWS Managed Service Kafka.
Outputs of the test: One set of results for the target AWS Managed Service Kafka server.
