Patent number: 10171360Abstract: A system detection method and apparatus. Throughput and response time of a system are acquired. Throughput reflects the number of requests processed by the system that are received from outside the system. The response time reflects time required to process requests from outside the system. A system performance characteristic parameter based on the throughput and response time is obtained and used to describe congestion of the system to determine bottlenecks in the system by at least obtaining system performance characteristic parameter based on the throughput and the response time and conducting noise filtering on the system performance characteristic parameter. A bottleneck is determined based on the noise filtered system performance characteristic parameter. The system detection method and apparatus allow detecting a bottleneck and flow control are provided in a simple and effective way to ensure that requests are processed in time.Type: GrantFiled: December 11, 2017Date of Patent: January 1, 2019Assignee: International Business Machines CorporationInventors: Ren Shi Luo, Asser N.

Patent number: 9871729Abstract: A non-transitory computer program product with computer readable program code for system detection and flow control. The throughput and response time of the system are acquired, where the throughput reflects the number of requests from outside the system that has been processed by the system. The response time reflects time required by the system to process requests from outside the system. Acquiring throughput and response time includes directly sampling the throughput and the response time of the system; and conducting noise filtering on the sampled throughput and response time. A system performance characteristic parameter based on the filtered throughput and response time is obtained and is used to describe congestion condition of the system to determine whether there is a bottleneck in the system. Detecting a bottleneck and flow control is provided in a simple and effective way to ensure that requests are processed in time.Type: GrantFiled: July 6, 2016Date of Patent: January 16, 2018Assignee: International Business Machines CorporationInventors: Ren Shi Luo, Asser N.
