OTEL-015: debug/logging exporter detected

Severity: warn (advisory)

Rule Details​

The debug exporter (formerly logging) prints telemetry to stdout. It is invaluable during local development but in production it floods logs, pins CPU on serialization, and fills disks. A Collector with debug wired into a live pipeline is almost always a debugging leftover that should be removed.

This rule fires when an exporter named debug or logging is present in the exporters block.

Options​

This rule has no options.

Examples​

Avoid
exporters:
  debug: {}
  otlp/backend:
    endpoint: backend:4317

service:
  pipelines:
    traces:
      receivers: [otlp]
      exporters: [debug, otlp/backend]
Prefer
exporters:
  otlp/backend:
    endpoint: backend:4317

service:
  pipelines:
    traces:
      receivers: [otlp]
      exporters: [otlp/backend]

When Not To Use It​

Local development and ad-hoc debugging sessions. Use a separate config file for that case instead of shipping debug to production.

  • OTEL-021 — unused exporter
  • OTEL-071 — logging exporter deprecated (renamed to debug)

Version​

Available since augur v0.1.0.
