HI Signoz team, I am facing an issue in traces. I am seeing missing spans in a trace in signoz. what happens is that when I perform a certain action on the app. a trace appears in signoz with all spans (No missing spans.) but after a while (1 min) a second trace appears that has M*issing spans* error. Although no other action is performed on the site. I have tried the solutions such as disabling the sampling and increasing the batch size of collector still the issue persists. Need urgent help as this issue has occurred in production env. P01012 appears two times. one has no missing spans --- whereas other has missing spans.

Which instrumentation library are you using?

I am using Inspectit-oceot-agent for instrumentation. It has configuration files for instrumentation i can share them as well those which are relevant to the traces that are having missing span issues.

Why are you not using official java opentelemetry agent? SigNoz users are using java otel agent on production and have reported it’s working fine.

Well inspectit is an all in one agent. this agent uses opentelemetry for instrumentaion. i am not sure whats causing the issue with traces and missing spans. i am using the default configurations at the moment for instrumentation. I have tried some configuration changes but the issue still persist. what could be the cause of the missing spans as per your analysis?

Official Otel java agent also is an all in one agent. Regarding missing spans, we are not sure about the cause but it’s very likely issue of the inspectit-oceot-agent.
