本文档记录Telegraf解析nginx access.log的相关内容

Tail Input Plugin

Tail Input Plugin 是 Telegraf项目众多Inputs插件之一。Tail Input Plugin 监听一个日志文件并解析该文件的每个日志变更。默认情况下，tail 插件的行为类似于以下 Unix tail 命令：

tail -F –lines=0 myfile.log

Telegraf收集nginx access.log 相当于Unix tail命令：

tail -F –lines=0 access.log

并使用grok格式来解析日志。除此之外，Telegraf Tail Input Plugin支持多种 Data Format细节的东西可以跟下源码，下面直接记录运行配置。

配置
