我已经使用Connectivity api将Eclipse hono与Eclipse ditto连接起来。当我设置它时,它工作正常。但是,一段时间后,转发连接失败。当我检索指标时,我得到以下响应:

}

}
}
}
我一直在检查提到的时间的日志,但我没有收到任何错误。我在这里发布的日志是上述时间戳(2019-03-19T21:00:16.466Z)之前的最后一个和之后的第一个。

尽管所有同上服务的日志级别都设置为调试,但我没有得到任何有用的日志记录。
你们有谁知道我如何让日志记录来调查这个问题,或者更好的是,知道问题可能是什么以及如何解决它?
当我删除连接并重新创建它时,一切都会再次按预期工作。也许同上可以自动在引擎盖下做到这一点?
更新
通过 API 检索连接时,我收到以下响应(包括设置为 true 的 failoverEnabled 属性)。这也表明该连接使用 AMQP 1.0。使用的经纪人是 Enmasse。
