[英]FIWARE QuantumLeap Sanity Check failed: QuantumLeap can't get changed data from Orion
我在 virtualMachine(带有 Ubuntu 的virtualBox)和生产服务器(CentOS)中检查了quantumLeap Sanity Check。 使用相同的 docker-compose.yml,在 virtualManchine 上的完整性检查成功,但在生产服务器上失败,这真的很奇怪,谁能帮助我? 非常感谢。 @杰森福克斯
健全性检查的步骤如下https://quantumleap.readthedocs.io/en/latest/admin/check/ ,我粘贴在下面。
结果的差异仅在第 7 步。在 virtualMachine 上,我可以从quantumLeap 获取更新的数据:
{
"attrName": "precipitation",
"entityId": "air_quality_observer_be_001",
"index": [
"2020-05-03T11:18:14.000",
"2020-05-03T11:18:55.000"
],
"values": [
0.0,
100.0
]
}
但是在生产服务器上,结果是:
{
"description": "No records were found for such query.",
"error": "Not Found"
}
笔记:
完整性检查步骤中的这些命令被复制到终端,因此不会有拼写错误。
结果的差异仅在第 7 步。我删除了 virtualMachine 和生产服务器上的旧图像,以便提取最新的图像。
在生产服务器上运行了一个基于固件的系统(orion、mongoDB、IoTAgents、quantumLeap、CrateDB、Grafana),一切都很好。 但是一周前,服务器上的硬盘已经满了,耗尽了,所有的容器都宕机了。 我清理了一些巨大的日志文件并释放了一些空间,然后我打开了基于固件的系统,发现 Grafana 上没有显示数据。 经过检查,我发现原因是QuantumLeap没有将数据存储到crateDB中,但我不确定根本原因是orion还是quantumLeap。 因此,我决定按照quantumLeap 文件的建议进行完整性检查。 这就是故事。
顺便说一句,quantumLeap 的订阅可以从 orion 获取,但我无法从quantumLeap 获取更改的数据。 为什么最新更改的数据没有同步到quantumLeap?
健全性检查步骤:
1.查看猎户座版本
curl -X GET http://0.0.0.0:1026/version -H 'Accept: application/json'
2.查看QuantumLeap版本
curl -X GET http://0.0.0.0:8668/version -H 'Accept: application/json'
3.为“QuantumLeap”创建 Orion 订阅
curl -X POST \
'http://0.0.0.0:8668/v2/subscribe?orionUrl=http://orion:1026/v2&quantumleapUrl=http://quantumleap:8668/v2&entityType=AirQualityObserved' \
-H 'Accept: application/json'
4.检查你的猫从猎户座获得这样的订阅
curl -X GET http://0.0.0.0:1026/v2/subscriptions \
-H 'Accept: application/json'
5.将AirQualityObserved的实体插入Orion
curl -X POST \
'http://0.0.0.0:1026/v2/entities?options=keyValues' \
-H 'Accept: application/json' \
-H 'Content-Type: application/json' \
-d '{
"id": "air_quality_observer_be_001",
"type": "AirQualityObserved",
"address": {
"streetAddress": "IJzerlaan",
"postOfficeBoxNumber": "18",
"addressLocality": "Antwerpen",
"addressCountry": "BE"
},
"dateObserved": "2017-11-03T12:37:23.734827",
"source": "http://testing.data.from.smartsdk",
"precipitation": 0,

"NO": 45,
"NO2": 69,
"NOx": 139,
"SO2": 11,
"CO_Level": "moderate",
"refPointOfInterest": "null"
}'
6.更新猎户座同一实体的降水量值。
curl -X PATCH \
http://0.0.0.0:1026/v2/entities/air_quality_observer_be_001/attrs \
-H 'Accept: application/json' \
-H 'Content-Type: application/json' \
-d '{
"precipitation": {
"value": 100,
"type": "Number"
}
}'
7.从quantumLeap查询同一实体的降水变化记录。
curl -X GET \
'http://0.0.0.0:8668/v2/entities/air_quality_observer_be_001/attrs/precipitation?type=AirQualityObserved' \
-H 'Accept: application/json'

没有解决,但有一点线索。
我从quantumLeap 那里得到了一些日志。 quantumLeap 中有一个 crate 客户端,原因可能是quantumLeap 中的 crate 客户端工作不正常。
我在这里粘贴日志:

解决了。 根本原因在于 crateDB。 当硬盘耗尽时,crateDB 关闭,每个表都设置为只读。 即使在磁盘空间被释放并且低于阈值之后,只读块也不会自动从表中删除。
在 crateDB 中使用以下命令将 readonly 标志设置为 false 后一切正常:
SHOW CREATE TABLE <tableName>;
ALTER TABLE <tableName> SET ("blocks.read_only_allow_delete" = FALSE);
