Question

我们一起使用 Idas / 猎户座 / Mongo （码头工作版）和 Cygnus 以便发送数据给Ckan和Cosmos。

我们模拟了100个传感器，每3分钟发送一次数据，这种方法在2天后停止工作，我检查了IDAS和Orion日志，并在日志中看到这些Mongodb错误，没有任何通知组件不再。

Idas日志：

您认为这与发送给Idas的数据数量有关吗？由于最大连接超过，mongodb停止了？

谢谢

Answer 1

Orion在无法访问数据库时显示cannot connect to mongo - doing 100 retries with a 1000 microsecond interval错误，例如当mongod服务器关闭时。我不是IDAS的专家，但我说couldn't connect to server 172.17.0.2:27017 (172.17.0.2), connection attempt failed错误导致了同样的原因。

因此，该问题的解决方案是确保MongoDB启动并运行并可从Orion和IDAS访问。

Orion Iot / Idas已达到最大的mongo池
