论文摘要
我们提供了裸金属硬件的正确尺寸的初步测试结果，该测试将托管Cherenkov望远镜阵列（CTA）的监视系统（MON）的数据库。 MON是阵列控制和数据采集系统（ACADA）的子系统，负责监视和记录整体CTA数组。它在每个CTA站点中获取并存储从数组元素中存储监视点和记录信息。 MON的设计和建造是为了处理大数据时间序列，并利用数据库和物联网（IoT）领域中一些当前最先进的技术。为了尺寸监视系统所需的裸金属硬件（不包括日志记录），我们执行了本文讨论的测试活动。我们在这里讨论最佳参数集和优化的配置，以每秒更新的行数量最大化数据库数据编写。我们还证明了我们在CTA要求框架中的可行性。
We present preliminary test results for the correct sizing of the bare metal hardware that will host the database of the Monitoring system (MON) for the Cherenkov Telescope Array (CTA). The MON is the subsystem of the Array Control and Data Acquisition System (ACADA) that is responsible for monitoring and logging the overall CTA array. It acquires and stores monitoring points and logging information from the array elements, at each of the CTA sites. MON is designed and built in order to deal with big data time series, and exploits some of the currently most advanced technologies in the fields of databases and Internet of Things (IoT). To dimension the bare metal hardware required by the monitoring system (excluding the logging), we performed the test campaign that is discussed in this paper. We discuss here the best set of parameters and the optimized configuration to maximize the database data writing in terms of the number of updated rows per second. We also demonstrate the feasibility of our approach in the frame of the CTA requirements.
