wso2 APIM和APIM之间的“读取超时”-分析

Question

Canario: APIM和APIM-Analytics (都在2.6.0中)在相同的本地主机上。其他计算机中的Identity Server使用该文档在APIM和Analytics之间进行配置。为外部Oracle DB实例设置te数据源: strat ok、Analytics Worker Start Ok、Analytics Dashboard start Ok、Analytics Manager Start Ok

默认配置后，Apim从连接问题开始：

当我访问控制台Analytics (发布者、商店或管理员)时，API Usage analtyics界面变得阻塞。

我尝试在api-manager.xml中做一些更改。现在分析部分如下：

    <!-- Enable Analytics for API Manager -->
    <Enabled>true</Enabled>

    <StreamProcessorServerURL>{tcp://localhost:7612}</StreamProcessorServerURL>
    <!--StreamProcessorAuthServerURL>{ssl://localhost:7712}</StreamProcessorAuthServerURL-->
    <!-- Administrator username to login to the remote StreamProcessor server. -->
    <StreamProcessorUsername>admin</StreamProcessorUsername>
    <!-- Administrator password to login to the remote StreamProcessor server. -->
    <StreamProcessorPassword>admin</StreamProcessorPassword>

    <!-- For APIM implemented Statistic client for RDBMS -->
    <StatsProviderImpl>org.wso2.carbon.apimgt.usage.client.impl.APIUsageStatisticsRestClientImpl</StatsProviderImpl>

   <!-- StreamProcessor REST API configuration -->
    <StreamProcessorRestApiURL>https://localhost:9444</StreamProcessorRestApiURL>
    <StreamProcessorRestApiUsername>admin</StreamProcessorRestApiUsername>
    <StreamProcessorRestApiPassword>admin</StreamProcessorRestApiPassword>

如果我遵循de default documentation (https://docs.wso2.com/display/AM260/Configuring+APIM+Analytics)，我希望发现为什么会发生这种情况，谢谢

这个问题通过将分析证书导入到wso2carbon.jks和client-truststore.jks得到了解决。一开始，我只是导入到client-truststore.jks，而忽略了wso2carbon.jks。使用全限定名创建新的证书和密钥库，并使用在api-manager.xml中建立工具之间的正确链接，这一点很重要。记住，在hosts文件中添加全限定名。

谢谢
