OTLP Receiver - ProvenLog

ProvenLog’s server can receive OpenTelemetry trace spans via OTLP/HTTP, mapping them to ProvenLog events with full attribute preservation.

Setup

# Start the ProvenLog server
plog serve

# Point your OTLP exporter at the ProvenLog endpoint
export OTEL_EXPORTER_OTLP_ENDPOINT=http://localhost:7600/v1/traces

How it works

The OTLP receiver accepts standard OTLP/HTTP requests (both Protobuf and JSON encoding) and converts each span into a ProvenLogEvent:

Span Field	Event Field
Span name	`action_name`
Span kind	Mapped to `action_type`
Attributes	`metadata`
Status	`action_status`
Duration	`duration_ms`
Trace ID	`session_id`

Use cases

Consolidate OpenTelemetry traces and ProvenLog audit events in one place
Add cryptographic integrity to existing OTLP instrumentation
Bridge existing observability pipelines into a tamper-evident audit trail
