fiware-orion - 通知限制有不良行为

Question

我已经部署了一个空 Orion 并连接了一个每 10 秒发送一次更新的设备。我需要每 10 分钟收到一个通知，因此我创建了一个限制为 600 秒的通知。

问题是我在第一个通知之后的同一分钟甚至几秒钟内收到了两个通知。

1）orion版本的一个实例：2.2.0

2) 猎户座订阅

3) Orion 在 docker 实例中运行

[root@271386b095c6 /]# ps ax
  PID TTY      STAT   TIME COMMAND
    1 ?        Ssl  320:12 /usr/bin/contextBroker -fg -multiservice -ngsiv1Autocast -dbhost mongo -corsOrigin __ALL -logLevel DEBUG

4) 待定...

5）实体和订阅属于同一个服务和服务路径

谢谢

查看上面的信息，您似乎有很多订阅。如果我数对了，其中六个。

不确定它们是否都涵盖相同的实体/属性，但我的建议是简化您的方案，只留下一个订阅并再次测试。

您可以使用 删除订阅DELETE /v2/subscriptions/{subId}。
