我正在尝试将 OpsCenter 与使用 CCM 创建的本地多节点开发集群一起使用。我已经使用这些说明为每个节点手动安装和配置了代理。我通过在 CQLSH 界面中上传 SOURCE 文件创建了我的自定义键空间及其列族

单击 Data > MyKeySpace > MyColumnFamily 时出现以下错误：

Error loading column family: Call to /test_cluster/keyspaces/flashcardsapp/cf/tag timed out.

但是，我可以查看 OpsCenter 键空间中的列族。

我在 OpsCenter 日志中看到以下内容：

我的环境如下：

  • 操作中心：opscenter-5.1.0
  • 代理：datastax-agent-5.1.0
  • 操作系统：OSX 10.10.1

OpsCenter 中存在一个已知错误，其中 Cassandra 2.1.x 中的 UUID 列未正确处理。我不知道任何解决方法（从 UUID 列切换或将 C* 降级到 2.0.x 应该可以工作，但可能工作量太大。）

它将在即将发布的 OpsCenter 5.1 补丁版本中修复（虽然不是 5.1.1）
