OpenTelemetry
File-based configuration
You can add _FILE to individual variables to provide their configuration in a separate file. Refer to Keeping sensitive data in separate files for more details.
n8n can export workflow and node execution traces over OTLP to an OpenTelemetry collector. Refer to OpenTelemetry tracing for details.
N8N_OTEL_ENABLED
Boolean
false
Whether to enable OpenTelemetry tracing. When set to false, n8n doesn't load the OpenTelemetry SDK.
2.19.0
N8N_OTEL_EXPORTER_OTLP_ENDPOINT
String
http://localhost:4318
Base URL of the OTLP HTTP endpoint to export traces to. n8n appends the value of N8N_OTEL_EXPORTER_OTLP_TRACING_PATH to this URL.
2.19.0
N8N_OTEL_EXPORTER_OTLP_TRACING_PATH
String
/v1/traces
Path appended to N8N_OTEL_EXPORTER_OTLP_ENDPOINT for exporting traces.

N8N_OTEL_EXPORTER_OTLP_HEADERS
String
-
Comma-separated list of key=value pairs to send as HTTP headers with each OTLP request. Use this for authentication tokens or tenant headers. For example: authorization=Bearer <token>,x-tenant=acme.

N8N_OTEL_EXPORTER_SERVICE_NAME
String
n8n
Value of the service.name resource attribute on exported spans.
2.19.0
N8N_OTEL_TRACES_SAMPLE_RATE
Number
1.0
Fraction of traces to export, between 0 and 1. n8n uses a trace ID ratio sampler, so all spans in a trace are either sampled or dropped together.
2.19.0
N8N_OTEL_TRACES_INCLUDE_NODE_SPANS
Boolean
true
Whether to emit a node.execute span for each node execution. Set to false to export workflow-level spans only.
2.19.0
N8N_OTEL_TRACES_PRODUCTION_ONLY
Boolean
true
Whether to export traces for production executions only. Set to false to export traces for all workflow executions.
2.25.2

Boolean
true
Whether to inject the W3C traceparent/tracesstate headers into outbound HTTP requests made by nodes that use n8n's HTTP helpers.
2.19.0
N8N_OTEL_STARTUP_CONNECTIVITY_TIMEOUT_MS
Number
2000
Timeout (in milliseconds) for the startup connectivity check against the OTLP endpoint. n8n logs a warning if the endpoint isn't reachable within this period.
