Hello, I have a question. Can Signoz be used only as a frontend for an already working open telelemtry collector ? I am running otel and exporting to Jaeger but can't figure out a good observability frontend so thought about signoz so basically Signoz minus the custom otel collector

SigNoz uses Clickhouse DB to store metrics/traces/logs. SigNoz otel collector exports to Clickhouse DB and SigNoz frontend/query service uses that data. So SigNoz otel collector is needed. You can use export from your already working open telelemtry collector to signoz otel collector and keep using SigNoz.
