FIWARE QuantumLeap 健全性檢查失敗：QuantumLeap 無法從 Orion 獲取更改的數據

Question

我在 virtualMachine（帶有 Ubuntu 的virtualBox）和生產服務器（CentOS）中檢查了quantumLeap Sanity Check。 使用相同的 docker-compose.yml，在 virtualManchine 上的完整性檢查成功，但在生產服務器上失敗，這真的很奇怪，誰能幫助我？ 非常感謝。 @傑森福克斯

健全性檢查的步驟如下https://quantumleap.readthedocs.io/en/latest/admin/check/ ，我粘貼在下面。

結果的差異僅在第 7 步。在 virtualMachine 上，我可以從quantumLeap 獲取更新的數據：

{
  "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
  ]
}

但是在生產服務器上，結果是：

{
  "description": "No records were found for such query.",
  "error": "Not Found"
}

筆記：

1. 完整性檢查步驟中的這些命令被復制到終端，因此不會有拼寫錯誤。

2. 結果的差異僅在第 7 步。我刪除了 virtualMachine 和生產服務器上的舊圖像，以便提取最新的圖像。

3. 在生產服務器上運行了一個基於固件的系統（orion、mongoDB、IoTAgents、quantumLeap、CrateDB、Grafana），一切都很好。 但是一周前，服務器上的硬盤已經滿了，耗盡了，所有的容器都宕機了。 我清理了一些巨大的日志文件並釋放了一些空間，然后我打開了基於固件的系統，發現 Grafana 上沒有顯示數據。 經過檢查，我發現原因是QuantumLeap沒有將數據存儲到crateDB中，但我不確定根本原因是orion還是quantumLeap。 因此，我決定按照quantumLeap 文件的建議進行完整性檢查。 這就是故事。

4. 順便說一句，quantumLeap 的訂閱可以從 orion 獲取，但我無法從quantumLeap 獲取更改的數據。 為什么最新更改的數據沒有同步到quantumLeap？

健全性檢查步驟：

1.查看獵戶座版本

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.為“QuantumLeap”創建 Orion 訂閱

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.檢查你的貓從獵戶座獲得這樣的訂閱

curl -X GET http://0.0.0.0:1026/v2/subscriptions \
-H 'Accept: application/json'

5.將AirQualityObserved的實體插入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,
    "relativeHumidity": 0.54,
    "temperature": 12.2,
    "windDirection": 186,
    "windSpeed": 0.64,
    "airQualityLevel": "moderate",
    "airQualityIndex": 65,
    "reliability": 0.7,
    "CO": 500,
    "NO": 45,
    "NO2": 69,
    "NOx": 139,
    "SO2": 11,
    "CO_Level": "moderate",
    "refPointOfInterest": "null"
}'

6.更新獵戶座同一實體的降水量值。

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.從quantumLeap查詢同一實體的降水變化記錄。

curl -X GET \
'http://0.0.0.0:8668/v2/entities/air_quality_observer_be_001/attrs/precipitation?type=AirQualityObserved' \
-H 'Accept: application/json'

docker-compose.yml的零件：

    container_name: fiware-orion
    depends_on:

    command: -Ccluster.name=democluster -Chttp.cors.enabled=true -Chttp.cors.allow-origin="*"
    volumes:

quantumleap:
    image: smartsdk/quantumleap
    hostname: quantumleap
    container_name: fiware-quantumleap
    expose:
      - "8668"
    ports:

    depends_on:
      - cratedb
    environment:
      - CRATE_HOST=cratedb # host name of CrateDB

沒有解決，但有一點線索。

我從quantumLeap 那里得到了一些日志。 quantumLeap 中有一個 crate 客戶端，原因可能是quantumLeap 中的 crate 客戶端工作不正常。

我在這里粘貼日志：

Answer 1

解決了。 根本原因在於 crateDB。 當硬盤耗盡時，crateDB 關閉，每個表都設置為只讀。 即使在磁盤空間被釋放並且低於閾值之后，只讀塊也不會自動從表中刪除。

在 crateDB 中使用以下命令將 readonly 標志設置為 false 后一切正常：

SHOW CREATE TABLE <tableName>;
ALTER TABLE <tableName> SET ("blocks.read_only_allow_delete" = FALSE);
