亿速云内容分发网络(Content Delivery Network,简称CDN)是建立并覆盖在承载网之上,由分布在不同区域的边缘节点服务器群组成的分布式网络。亿速云CDN分担源站压力,避免网络拥塞,确保在不同区域、不同场景下加速网站内容的分发,提高资源访问速度。许多用户在实际运用CDN的过程中都会遇到一些CDN常见的问题,今天小编跟大家聊一下公司使用快网的CDN的问题。
公司使用的快网的CDN,但是快网本身并不提供日志的分析统计,我这里还没有用elk,无奈只能先使用shell对日志进行分析统计,作为运维组对业务情况的一个大致的了解。
脚本是对前一天的CDNLOG进行解压缩分析,最后将结果按类输出到指定目录,再将这些结果打包扔回CDNLOG目录,因为CDNLOG目录是要上传云存储的,一并保存。其实还有一个动作,是将这些内容作为参数传给python脚本给一个监控系统,出图便于查看,这里没有贴上。
同样作为留底,不喜勿喷。
