前一阵子,搭建了ELK日志分析平台,用着挺爽的,再也不用给开发拉各种日志,节省了很多时间. 这篇博文是介绍用python代码实现日志分析的,用MRJob实现hadoop上的mapreduce,可以直接放到hadoop集群上运行. mrjob可以让我们使用Python编写MapReduce运算,并在多个不同平台运行,你可以: 使用纯python编写multi-step MapReduce 本机测试 在hadoop集群上运行 安装mrjob pip install mrjob nginx访问日志格式…

日志服务支持通过数据接入向导配置采集Nginx日志,并自动创建索引和Nginx日志仪表盘,帮助您快速采集并分析Nginx日志. 许多个人站长选取了Nginx作为服务器搭建网站,在对网站访问情况进行分析时,需要对Nginx访问日志统计分析,从中获取网站的访问量.访问时段等访问情况.传统模式下利用CNZZ等方式,在前端页面插入js,用户访问的时候触发js,但仅能记录访问请求.或者利用流计算.离线统计分析Nginx访问日志,但需要搭建一套环境,并且在实时性以及分析灵活性上难以平衡. 日志服务在支持查询…
