WSO2 DAS +使用mysql集群APIM

我的APIM版本是1.10.0，DAS是3.0.1。WSO2 DAS +使用mysql集群APIM
起初，我没有使用mysql部署集群APIM + DAS。统计数据显示良好。
然后，我聚类APIM到出版商，存储的KeyManager和gateway.Configured APIM和DAS订购this article，当调用的API，网关节点则显示错误

然后我改变了DAS配置的方式。以下this blog，我配置的所有API-manager.xml，没有错误，并且没有stats.And存储节点节目信息：

[2016-10-18 11:31:39,131] INFO - ReceiverGroup Resending the failed published data... 
[2016-10-18 11:31:44,134] WARN - AccessConfiguration Error loading properties from file: access-log.properties 
[2016-10-18 11:31:44,207] INFO - TimeoutHandler This engine will expire all callbacks after : 120 seconds, irrespective of the timeout

我谷歌的原因，在wso2 jira，他们说这不是一个错误。

但我不能等待我的统计数小时。我配置错了什么？

调节器。

您可以通过登录到DAS管理控制台来浏览DAS表。您可以浏览Data Explorer菜单中的org.wso2.apimgt.statistics.request表。还要确保你已经在/repository/deployment/server/carbonapps/dir – ruks

上部署了Capp，在Data explorer菜单下的表org.wso2.apimgt.statistics.request中没有数据，ORG_WSO2_APIMGT_STATISTICS_WORKFLOW表获得一些数据。在/repository/deployment/server/carbonapps /下是API_Manager_Analytics_RDBMS.car。没有分布式APIM，我可以从发布商和商店获取统计信息。发布时，没有统计信息 –

似乎在商店节点，数据正在发布启用和工作。但是网关节点数据没有发布。请尝试验证网关节点配置。同时检查网关节点是否可以访问DAS节点。

谢谢，垃圾。商店和网关节点的api-manager.xml配置是相同的。是否有其他配置？如何检查网关节点是否可以访问DAS节点？在步骤2中，我可以证明DAS可用吗？或者DAS接收器没有收到消息？ –

我使用没有分布式APIM与DAS，在调用api后，有统计信息。然后我将APIM更改为DISTRIBUTED，然后我调用另一个API，统计信息显示SubscriberCount但没有命中。 –

但在数据浏览器菜单中的DAS管理控制台，我找不到新的调用API数据。网关无法发送或DAS无法接收？以及如何解决？ –
