@Rock Sun The troubleshoot binary checks if the otel-collector grpc endpoint is accessible with dummy data. However, since the dummy data is incomplete, it is rejected by SigNoz OtelCollector with the error above.
If you wish to make sure that otel-collector endpoint is accessible as well as the telemetry data is accepted, you can make use of
telemetrygen
. https://pkg.go.dev/github.com/open-telemetry/opentelemetry-collector-contrib/cmd/telemetrygen#section-readme
The sample trace/metrics sent using it can be verified from SigNoz UI.
