Sending telemetry to Azure Data Explorer

[tashivani]

I'm currently facing issues with sending telemetry data from a C++ desktop application to Azure, specifically Azure Data Explorer.

In my project, telemetry is being sent via a gRPC exporter to a collector on the same machine. This collector successfully writes the telemetry data to local files. However, when attempting to send the data to Azure, I find that no data appears in the Azure Data Explorer (ADX) tables that I have set up.

I haven't noticed any error messages from the collector, which makes the issue even harder to troubleshoot. As a reference, I've been following the steps laid out in the Azure documentation for creating an Azure Active Directory application registration in Azure Data Explorer (link).

To help identify if there is any configuration issue, I have attached the OpenTelemetry (otel) collector YAML file (otel-collector.yml) here.

I'm at a bit of a loss for how to proceed with debugging this issue. If anyone could provide some guidance, or even better, a working example that I could compare to, it would be greatly appreciated.

Thanks in advance for your help!
