这篇文章主要介绍了基于python3抓取pinpoint应用信息入库,文中通过示例代码介绍的非常详细，对大家的学习或者工作具有一定的参考学习价值,需要的朋友可以参考下

Pinpoint是用Java编写的大型分布式系统的APM（应用程序性能管理）工具。受Dapper的启发，Pinpoint提供了一种解决方案，通过在分布式应用程序中跟踪事务来帮助分析系统的整体结构以及它们中的组件之间的相互关系.

pinpoint api:

/applications.pinpoint 获取applications基本信息
/getAgentList.pinpoint 获取对应application agent信息
/getServerMapData.pinpoint 获取对应app 基本数据流信息
