Data Analytics Server 3.1.0 抛出异常

Question

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

在 api-manger.xml
将其定向到我的 DAS 服务器端口
已将 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/Running+the+Product#RunningtheProduct-AccessingtheManagementConsole https://docs.wso2.com/display/AM200/Configuring+APIM+Analytics docs.wso2.com/display/DAS310/Quick+开始+指南

但我收到以下错误：

由于服务器未获得某些流定义，
我还尝试部署 APIM_Realtime_Analytics_REST.car（从以前版本的 DAS）但无济于事。我收到了类似的例外情况

我该如何纠正这个问题？
提前致谢！

Answer 1

如the document you are referring所述，现在APIM有自己的Analytics Server，也就是定制的DAS。所以现在您只需进行很少的配置即可查看 API 统计信息。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，据我了解，您使用的是原始 DAS 服务器，而不是 APIM 分析服务器。如果可能的话，请尝试一下。如果由于某种原因您不能，请从该发行版中获取汽车文件并将其安装到 DAS 中。那应该可以解决您的问题。
