无法为 ssl://wso2apim-analytics-service.domain.com:7712 借用客户端

Question

我正在设置多区域 WSO2 APIM 环境。从属区域中的网关组件无法连接到主区域中的 API 分析组件，出现以下错误：

已在从属区域启用分析。此外，我们还可以通过端口 7712 远程登录到主区域中的分析服务。

为什么会发生 "java.net.SocketTimeoutException: Read timed out"？

Answer 1

有很多点你应该检查。

从域上的域名解析。
检查从站到主站的连接、防火墙规则等
检查双方的证书，是否与域名匹配。

使用openssl s_client -connect wso2apim-analytics-service.domain.com:7712

祝你好运。

Answer 2

Once the debug logs are enabled for below class, when graphs are selected for analytics, it will log the Siddhi queries it sends to the analytics server. 这将帮助我们捕获发布者门户发送到分析服务器的确切查询，并尝试识别任何可用的罪魁祸首点。

关闭服务器。
将以下属性添加到 /repository/conf/log4j.properties log4j.logger.org.wso2.carbon.apimgt.impl.utils.APIUtil=DEBUG
重启服务器
