The eSDK Demo forwards data in real time, but the metadata subscription does not contain data.
1) On the CSP portal, check whether the VCM information is configured for the VCN analysis platform and whether the metadata subscription table contains the connection information of the corresponding VCM platform.
IMGU database table of the VCM metadata subscription data:
1, TBL_DEVICE_METADATA_SUBSCRIBER
2, TBL_DEVICE_METADATA_SUBSCRIBEINFO
Run the following statement to query the database: Access the MPU container where the device is located and run the following command:
su - postgres -c "psql scu -c' select * from TBL_DEVICE_METADATA_SUBSCRIBER '";
Check whether the configured analysis platform exists in the database. If not, the client (portal) may not be configured.
su - postgres -c "psql scu -c' select * from TBL_DEVICE_METADATA_SUBSCRIBEINFO '";
Check whether the camera to which the metadata is subscribed exists in the database. If not, the client (VCM) may not be configured (although the page displays a success message).
Demarcation method: Enable the IMGU debug log function and perform operations on the GUI to check whether "CImgMediaService::HandleMetadataSubscribe Start" (debug-level logs) is recorded in the IMGU logs. If no, the IMGU logs are not delivered to the IMGU. Contact the analysis personnel to check the logs.
Note: If the analysis platform connected to the CSP portal is deleted, the subscription information in the data table is cleared, but the subscription status may still be displayed on the CU.
2) Check whether the account secret configured on the platform is correct. Search the IMGU log for the HTTP login keyword and check whether the account is locked and whether the user name or password is incorrect.
If the account password is incorrect or locked, reconfigure the password of the analysis platform account. The account created for the first time must be logged in to and changed once. Otherwise, the account is locked due to incorrect password.
3) If the problem persists, check whether the IMGU pushes data. Search for the keyword strUrl in the IMGU log. If the keyword is found, the IMGU pushes data.
The log description is as follows:
Facial data: /sdk_service/rest/adaptor/vcn/facedata
Personal data: /sdk_service/rest/adaptor/vcn/additionaldata
Motor vehicle (cyclist data): /sdk_service/rest/adaptor/receiveVCNMetadata
