How to drop logs containing "[CLIFE-TRACE-LOG]" using OpenTelemetry Collector in SigNoz?

[lynyuxuan]

We're using the **OpenTelemetry Java Agent to automatically capture application logs (from stdout / logback) and send them directly to SigNoz via OTLP/gRPC.

Some of our logs contain lines like:[CLIFE-TRACE-LOG]|[2025-11-19 10:26:11:118]|[]|[10.244.96.85]

These are internal trace logs that we do not want to ingest — they generate high volume but no operational value.

Goal

Drop any log record whose body contains the literal string [CLIFE-TRACE-LOG] at the OpenTelemetry Collector level, before it reaches ClickHouse.

Question

Can we use the filter processor in SigNoz’s OTel Collector to exclude logs by substring match in body?
