Method and apparatus to facilitate measurement of quality-of-service performance of a network server

摘要

One embodiment of the present invention provides a system that facilitates measuring quality-of-service of a computer network server or collection of servers by determining the effect that transactions in one category of service have on transactions in other categories of service. The system operates by generating a varying pattern of synthetic transactions for one category of service and a fixed pattern of synthetic transactions for the other categories of service. The system sends the varying pattern and the fixed pattern of synthetic transactions and receives responses to these patterns across a network between the computer network servers and the synthetic transaction generator. The system measures the response time for the varying pattern of synthetic transactions and the response time for the fixed pattern of synthetic transactions. Additionally, the system calculates the effect of transactions in one category of service on response times in the other category of service.
