Orion Iot/Idas 已达到最大 mongo 池

Question

我们正在使用 Idas/Orion/Mongo(docker build) 和 Cygnus 一起发送数据给 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，没有不再有来自两个组件的任何通知。

Idas 日志：

您认为这与发送到 Idas 的数据数量有关吗？并且 mongodb 由于超过最大连接数而停止？

感谢

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 专家，但我会说 couldn't connect to server 172.17.0.2:27017 (172.17.0.2), connection attempt failed 错误指向相同的原因。

因此，问题的解决方案是确保 MongoDB 启动并且运行并且可以从 Orion 和 IDAS 访问。
