Masakari>我想使用我在控制器节点和masakari-processmonitor、masakari-instancemonitor和masakari-hostmonitor masakari-api和masakari-engine在控制器节点上安装的项目为我的 Openstack 实例 HA 创建实例 HA，但是当我要测试失败的服务openstack-nova-compte测试实例 HA 时，我收到此错误：

- 我检查了与控制器节点和计算节点的连接，所有这些都正常。
- 我检查了Rabbitmq队列，它有masakari ha引擎队列。
- 我检查了 MySQL 的 masakari 数据库，我也有。
mysql> SHOW TABLES FROM masakari;
failover_segments
hosts
migrate_version
notifications
每件事看起来都正确，但我的问题在哪里，我错过了一些东西。
问题似乎是
属性错误："连接"对象没有属性"instance_ha"。
在稳定/皇后中，此问题已通过此补丁修复。
如果您在稳定版/皇后版或任何其他版本中仍然发现此问题，我建议您通过launchpad向OpenStack masakari-monitors提交错误报告。请包括OpenStack版本的详细信息。
