OTEL-069: Telemetry metrics level set to none

Severity: warn (advisory)

Rule Details​

The Collector's own metrics (otelcol_process_cpu_seconds, otelcol_exporter_queue_size, otelcol_receiver_accepted_spans, …) are what oncall looks at when the pipeline starts dropping data. Setting service.telemetry.metrics.level: none turns them all off, leaving operators blind. Keep it at normal (the default) or detailed for noisy environments.

This rule fires when service.telemetry.metrics.level == "none".

Options​

FieldConstraint
service.telemetry.metrics.levelShould be normal or detailed

Examples​

Avoid
service:
  telemetry:
    metrics:
      level: none
Prefer
service:
  telemetry:
    metrics:
      level: normal

When Not To Use It​

Never — the Collector's internal telemetry is essential for operating it.
