我正在使用WSO2 Kubernetes Artifacts来构建WSO2 APIM 1.10.0集群 .

这是我的配置：

  • api-key-manager.yaml

  • api-publisher.yaml

  • api-store.yaml

  • gateway-manager.yaml

通过上述配置，APIM集群在我的kubernetes环境中运行良好 . 然后我想从WSO2 DAS 3.0.1获取统计数据 . 这是我的步骤 .

  • 打开管理员仪表板页面 .

  • 填写DAS信息 .

  • 保存配置 .

  • 发布示例API并订阅它 .

  • 调用创建的API .

虽然API返回正确的结果，但我看不到DAS页面的任何统计信息 . 表 ORG_WSO2_APIMGT_STATISTICS_REQUEST 也是空的 . 此外，网关容器中有一些例外情况如下：

问题可能与this issue相同，但我没有看到解决方案 .

Edit 1

我还做了两个实验如下 .

第一：

  • 创建一个ubuntu pod .

  • 在ubuntu pod容器上安装WSO2 APIM 1.10.0 .

  • 打开管理仪表板页面并填写DAS信息 .

  • 发布示例API并订阅它 .

  • 调用创建的API .

哪个工作正常 . 我可以从DAS页面看到统计信息 .

第二：

  • 跳转到APIM容器 .

  • 使用telnet验证DAS集群的thrift端口 .

可以访问APIM群集的thrift端口 .

根据例外，我认为这可能是由于网关容器中缺少配置引起的？
