专门为kettle这款优秀的ETL工具开发的web端管理工具。 kettle作为非常优秀的开源ETL工具得到了非常广泛的使用，一般的使用的都是使用客户端操作管理，但问题是当投入生产环境使用时，动辄上百或几百个job需要管理，这时在使用客户端管理已经很难完成了。我所知道的解决方案有用命令行的调用的，操作麻烦，总之还是很难用啦，还有就是开发web端管理工具，kettle自带了一个web端管理工具，界面极其简陋不说，还很难用，基本无法投入生产环境使用，其他没留意到还有没有较好对众多job进行管理的工具。(A web-side management tool specially developed for kettle, an excellent ETL tool.
