数据点Data Point:数据源在某个时间产生的某个量测指标值(Field Value)称为一个数据点,数据库查询、写入时按数据点数来作为统计指标; 时间线 Time Series:数据源的某一个指标随时间变化,形成时间线,Metric + Tags + Field 组合确定一条时间线;针对时序数据的计算包括降采样、聚合(sum、count、max、min等)、插...
Set Functions for Time Series [时间序列论文]Set Functions for Time Series 解决问题 模型 概念 提出模型 Attention-based Aggregation 实验 任务 数据集 对比方法 实验结果 解决问题 1)不规则采样 2)不同的测量步长 模型 概念 1、Time series,我们定义时间序列为一个集合 S i S_i Si,集合长度为M。即:...

TB级别time series data的索引和挖掘 编者对文章的总结 本文基于SAX提出了iSAX,是对时间序列的一种抽象表示法,可以动态扩展其维度,以此构造树形结构的索引。这种索引主要的功能是应对相似搜索(similarty search),其它功能作者并未提及。在similarty search中,近似结果的获得是非常快的,在秒的级别;精确结果的搜索性能则...

Zabbix, Time Series Data and TimescaleDB By alexk May 7, 2019 Every monitoring system has to deal with three kinds of performance-related challenges.Firstly, a good monitoring system must receive, process and record incoming data very quickly. Every microsecond counts here. This may not seem ...
Since it would be inefficienttowriteevery measurementtothe database, collectors pre-aggregate the dataandwritetothe time series database at regular intervals. 由于将每个测量值写入数据库的效率很低,收集器会预先聚合数据,并定期写入时间序列数据库。
