Abstract

Embodiments of the present disclosure provide a method and device for determining a cause of performance degradation of a storage system. The method includes: monitoring the performance of the storage system according to a predetermined strategy; generating a corresponding performance degradation event based on the system performance baseline according to the monitoring result; obtaining information related to the performance degradation in response to the performance degradation event; and The information is analyzed offline to determine the cause of performance degradation. Compared with the prior art, the embodiments of the present disclosure can effectively continuously manage system performance degradation, minimize running overhead, and support existing performance analysis tools through plug-in.

Description

technical field [0001] Embodiments of the present disclosure generally relate to system performance, and specifically relate to a method and device for determining the cause of storage system performance degradation. Background technique [0002] Locating the cause of performance degradation in a complex system, especially a production system, is quite difficult and time-consuming. Although consistent performance is often one of the system design goals, almost every system suffers from unexpected performance degradation in practice, especially those built with many components, layers, or complex logic. Causes of system performance degradation typically include, for example, design and / or implementation flaws or limitations, software configuration issues, and / or hardware limitations. Design and / or implementation flaws or limitations can be about specific components, such as locking or serialization on critical I / O paths; or more generally can be unexpected interactions betwe...
