为什么我无法在WSO2 API Manager Store中查看统计信息？

Question

每个人都请注意，这个问题已经更新，因为我最近有日志可以使用。在日志下面是我的配置的原始帖子，以及我看到的行为。 今天，WSO2 APIM继续发送给更新统计数据库的BAM接收器。但是，当我点击发布者中的任何统计信息链接时，我得到：

我已将WSo2 API Manager 1.6.0和BAM 2.4.0配置为使用与WSO2AM_STATS_DB相同的数据源配置。 对于商店，它是单个WSO2AM_STATS_DB条目，与BAM服务器上的条目匹配（如下），API-Manager.xml更新为：

  <APIUsageTracking>
        <Enabled>true</Enabled>
<PublisherClass>org.wso2.carbon.apimgt.usage.publisher.APIMgtUsageDataBridgeDataPublisher</PublisherClass>

             <TrackingID>UA-XXXXXXXX-X</TrackingID>
       </GoogleAnalyticsTracking>
    </APIUsageTracking>

现在是APIM的数据源：

当我查看mydbserver / wso2_apiStatsdb时，我看到下面的表已经创建并且已经使用数据进行了更新：

API_REQUEST_SUMMARY，API_Resource_USAGE_SUMMARY 更新：添加并更新了一些其他表... API_FAULT_SUMMARY，API_RESPONSE_SUMMARY，API_VERSION_USAGE_SUMMARY

然而，当我进入发布商页面时，我得到：

据我所知，我已经更新了发布者/商店和网关/密钥管理器，以便将数据发送到BAM服务器。 BAM服务器似乎处理并将该汇总数据放入sql server数据库中。我的SQL Server数据库条目匹配发布者/存储配置和BAM服务器配置。有没有人有任何我想念的想法，这使我能够在发布者时看到统计数据？

Answer 1

请检查EnableBillingAndUsage是否设为false。这可以在conf / api-manager.xml中找到

<EnableBillingAndUsage>false</EnableBillingAndUsage>

Answer 2

您是否在端口偏移1上运行BAM？据我所知，你在不同的服务器上运行BAM。尝试使用端口偏移量1运行BAM。站点中提供的默认配置是用于API Manager和BAM在具有端口偏移的同一服务器上运行的用例（API M -0和BAM -1）。因此，默认配置中所有相关的thrift端口也会增加1。因此我建议你在偏移1上运行BAM。

在此期间，请检查具有汇总统计信息的MQSQL DB是否包含其中的任何数据。

Answer 3

如果您尚未在API Manager中正确配置汇总数据库，也会发生这种情况。根据您的提及，API Manager似乎正确地发布数据，但它不提取汇总数据。请查看您是否在APIM目录中的master-datasources.xml中定义了WSO2AM_STATS_DB。

Answer 4

Gammonster，这已被弄清楚了。看起来魔鬼确实在细节中 - 运行时试图在SQL Server数据库中使用'limit'关键字执行sql查询，而SQL Server不支持'limit'。它有'顶'而不是。

如果产品文档明确指出SQL Server不是BAM的首选数据库实例，那将不胜感激。
