我已使用 Check_MK 版本 1.5.0p13 配置了 AWS 监控（按照官方 Check_MK 网站上的文档操作）。除 RDS 检查外，一切正常，当我去发现服务时，我得到：
Service discovery failed for this host: 'DBName'
我可以做些什么来调试此问题？在哪里可以获得更多输出？有什么方法可以解决这个问题吗？
这是输出：
cmk -vI aws

答案1
问题是一个错误，其中“DBName”用于标识数据库，但该值并不总是设置。现在它使用“DBInstanceIdentifier”。
在 1.5.0p14 和 1.6.0i1 版本中修复。
如果你想实施修复，你可以找到提交差异官方 Check_MK git 存储库。
