摘要：Changes in operating environment may result in the performance degradation to a SaaS software. Analyzing running log is an efficient method to locate this problem. However, as a long-running software, SaaS may generate huge log data which is difficult to analyze, and it lacks a systematic approach to implement management of the running log. These all threaten the timeliness of SaaS performance analysis. In this paper, we define a log format to standardize multi-source heterogeneous log data and construct a log model to support SaaS software performance analysis, where the two performance metrics of average response time and request timeout rate in the model are calculated by statistical measurement. Furthermore, a log management framework is given to support real-Time big log data collection, access, calculation, storage and service, and the technology implementation of the framework is also given. Finally, a case study is given to illustrate and validate the effectiveness of the approach.
