exception - 数据分析服务器 3.1.0 抛出异常

我正在使用 WSO2 API Manager 2.0.0 和 WSO2 DataAnalyticsServer 3.1.0。
我做了以下配置:

在 api-manger.xml 中启用分析

将其定向到我的 DAS 服务器端口

将 DAS_AGENT 添加到 log4j 属性

服务器正常启动
在 DAS 的管理控制台中，我上传了 APIM_Realtime_Analytics.car
所有这一切都符合:

https://docs.wso2.com/display/AM200/Configuring+APIM+Analytics
docs.wso2.com/display/DAS310/Quick+Start+Guide

但我收到以下错误:

由于服务器没有获得某些流定义，
我还尝试部署 APIM_Realtime_Analytics_REST.car(来自以前版本的 DAS)但无济于事。我得到了类似的异常(exception)

我该如何纠正？
提前致谢!

最佳答案

正如在the document you are referring to 中提到的，现在APIM 有了自己的Analytics Server，这是一个定制的DAS。所以现在你需要做很少的配置来查看 API 统计信息。该发行版也已经安装了 CApps。所以你不需要手动安装它们。

但是，据我所知，您使用的是 vanilla DAS Server 而不是 APIM Analytics Server。如果可能，请尝试这样做。如果由于某种原因不能，请从该发行版中获取汽车文件并将其安装在 DAS 中。那应该可以解决您的问题。
