No Collector

Why and how to send signals directly from app to backends

The simplest pattern is not to use a collector at all. This pattern consists of applications instrumented with an OpenTelemetry SDK that export telemetry signals (traces, metrics, logs) directly into a backend:

No collector deployment concept


See the code instrumentation for programming languages for concrete end-to-end examples for how to export signals from your app directly into a backend.



  • Simple to use (especially in a dev/test environment)
  • No additional moving parts to operate (in production environments)


  • Requires code changes if collection, processing, or ingestion changes
  • Strong coupling between the application code and the backend
  • There are limited number of exporters per language implementation
