Summary

  • Drop successful Redis spans regardless of the exporting service name.
  • Match both db.system and the newer db.system.name semantic-convention attribute.
  • Preserve Redis spans whose status is STATUS_CODE_ERROR and retain the existing Message: EntityChanged filter.

Root cause

The cache-span filter was scoped to two fixed service.name values. A deployment renamed a service, so its successful Redis spans stopped matching the filter and were exported to SigNoz.

Validation

  • git diff --check
  • Rendered signoz/k8s-infra chart 0.16.0 with helm template and confirmed filter/drop_cache_spans is present in the node-agent traces pipeline after chart-injected processors and before batch.

Breaking changes

None.
