Hi team, I am experience missing traces in signoz. I was using tempo and migrating to signoz. The traces that I was able to find in tempo was not available in signoz. I use opentelemetry collector to send trace to both tempo and signoz. At the time the trace is generated, my opentelemetry collector

otelcol_exporter_send_failed_spans

was not increasing, and on signoz side, the

otelcol_receiver_refused_spans

was 0,

otelcol_receiver_refused_spans

was 0. Is there a way to trouble shoot why the span is missing?

Do you see any error logs in signoz-otel-collector?

No, no errors in otel-collector.

If there are no errors in otel-collector and

otelcol_

metrics do not show any drop then nothing is ever dropped. How do you what span is missing?

I have tempo as another backend with same datasource, I was able to find the corresponding traces in tempo

How is data sent to both?

Using opentelemetry collector

It can't go randomly missing and yet does not show any errors. Make sure your expected trace actually reaches the SigNoz.
