<@U01HPVB0D2S> I am still not clear on missing spans. Can any one guide on this?

<@U04V7BD44B1> It might be due to
• sampling. Do you do some sampling before sending to SigNoz?
• otel-collectors at SigNoz or agents not sending all spans due to high load

<@U04V7BD44B1> how many spans/s are you sending to SigNoz?

3rd reason could be  - you are viewing the spans in UI before a trace is complete. This is usually the case with long running request, background jobs, async services. How much time do you see a trace take when it has no missing spans. Probably check for an older data like 1hr, 6hr ago
