If you can share more details on how your otel collectors are deployed currently - we should be able to help you out.
Couple of common depoyment models:
1. run otel collectors in nodes ( as agents) and send from these otel collector to SigNoz otel ollector
2. send data directly from applications to SIgNoz otel collector
SigNoz is an open-source APM. It helps developers monitor their applications & troubleshoot problems, an open-source alternative to DataDog, NewRelic, etc.
