随着近几年国内信息化水平不断提高,国网浙江电力主机、网络等设备数量急剧上升,业务系统的访问和操作量也迅速增加,传统的日志审计系统在应对超大规模海量日志的存储和分析时能力明显不足.针对海量日志采集、处理的需求,结合国网浙江省电力公司的实际情况,提出了一种基于开源ElasticSearch(弹性搜索)和Logstash(日志采集)的统一日志分析系统,并整合强隔离装置、toprowMQ消息队列、Kafka消息队列、Spark Streaming流数据处理框架,保证数据的安全性、可靠性和实时性.最后,通过日志分析系统在国网浙江电力的应用情况,验证了该系统的功能.

This paper deals with an intelligent image processing method for the video surveillance systems. We propose a fast and robust algorithm for moving target detection which combines Binarized Normed Gradients (BING) Objectness and background estimation. A real-time surveillance system needs to detect moving objects robustly against noises and environment. So the proposed method uses a simple background estimation model with a sensitivity parameter to extract a set of rough moving foreground in image. We also use objectness detection within the foreground set to estimate another set of candidate object windows. Then the target (pedestrians/vehicles) region by the intersection of areas derives from the former two steps. To track moving objects fast, the proposed method predicts the velocity and the direction of the groups formed by moving objects. Besides, time cost is reduced by the decrease of estimation regions. Experiments on the outdoor datasets show that the combined method can not only achieve a high detection ratio (DR) but also decrease false alarm ratio (FAR), as well as time cost. Finally, the experiments show that the proposed method has the robustness against the environmental influences and the speed, which are suitable for the real-time surveillance system.

This paper introduces the research and practice of an unified application system monitoring platform for Zhejiang electric power company. As an overall and unified end-to-end application system monitoring platform, the platform fully monitors and analyzes various history data from different levels such as OS, application, network, host and storage, applications-related information and service operation information. And then this paper constructs a set of complete methodology to detect, identify, locate and solve problems through the monitoring of application level. Finally, several typical scenarios are described by practical application examples. Application results show that various standardized operation and maintenance means and report data provided by the unified application system monitoring platform provides a full range of support for several departments such as the operation and maintenance department, the production department, the decision department and the management department.
