Data Analytics Server 3.1.0抛出异常

Question

我正在使用WSO2 API Manager 2.0.0

1. 启用api-manger.xml分析
2. 将其引导到我的DAS服务器端口
3. 添加DAS_AGENTlog4j属性

服务器正常启动
在DAS的管理控制台中，我上传了APIM\u实时\u分析。所有这些都符合：https://docs.wso2.com/display/AM200/Running产品#运行产品访问管理控制台https://docs.wso2.com/display/AM200/ConfiguringAPIM分析文档。wso2。com/display/DAS310/快速入门指南

但我得到了以下错误：

由于服务器没有获得特定的流定义，
我还尝试部署APIM\u Realtime\u Analytics\u REST。汽车（从以前版本的DAS），但没有用。我得到了类似的例外

我该如何纠正这一点？
提前感谢！

Answer 1

正如您提到的文档中提到的，现在APIM有自己的Analytics Server，这是一个定制的DAS。因此，现在您需要进行一些配置来查看API统计数据。该发行版也已经要求安装CApps。所以你不需要手动安装它们。

但是，据我所知，您使用的是香草DAS服务器，而不是APIM分析服务器。如果可能的话，请尝试一下。如果由于某种原因不能，请从该发行版获取car文件并将其安装到DAS中。这应该能解决你的问题。
