OpenTelemetry Configuration

OpenTelemetry gives kprobe application context. It tells kprobe which request, service, span, or transaction was active when a kernel event occurred.

Enable correlation

otel:
  enabled: true
  endpoint: otel-collector.observability.svc.cluster.local:4317

Recommended attributes

Emit these attributes when possible:

Attribute	Example
service.name	ledger-service
service.namespace	payments
deployment.environment	production
kprobe.transaction_id	pay_123
http.route	/payments/{id}/capture
db.operation	write

Searchable business IDs

For incident response, the most useful field is the one operators already know:

payment_id
query_id
order_id
job_id
transaction_id

Map that value to kprobe.transaction_id or configure a custom transaction field.
