Hello Sammie Yuen, thanks for sharing this query on this forum. Glad to see there are no blockers with your application.
The error code 500.321.998.100 in Azure IoT Central data export could be caused by several factors such as network connectivity issues, storage issues, or problems with the data export process. It is recommended to check network connectivity issues, storage issues, or problems with the data export process. Verify the data export settings and ensure they are correct!!
IoT Central applications have an internal audit log to track activity within the application.
In IoT Central, the Data export page lets you check the status of your exports. You can also use Azure Monitor to see how much data you're exporting and any export errors. You can access export and device health metrics in charts in the Azure portal, with a REST API, or with queries in PowerShell or the Azure CLI. Currently, you can monitor the following data export metrics in Azure Monitor:
- Number of messages incoming to export before filters are applied.
- Number of messages that pass through filters.
- Number of messages successfully exported to destinations.
- Number of errors found.
