OpenTelemetry setup #

VictoriaTraces supports both client open-telemetry SDK and collector .

Client SDK #

The OpenTelemetry provides detailed document and examples for various programming languages:

To send data to VictoriaTraces, specify the EndpointURL for http-exporter builder to http://<victoria-traces>:10428/insert/opentelemetry/v1/traces.

Consider the following example for Go SDK:

      traceExporter, err := otlptracehttp.New(ctx,
	otlptracehttp.WithEndpointURL("http://<victoria-traces>:10428/insert/opentelemetry/v1/traces"),
)
    

VictoriaTraces automatically use service.name in resource attributes and name in span as stream fields . While the remaining data (including resource , instrumentation scope , and fields in span , like trace_id, span_id, span attributes and more) are stored as regular fields :

VictoriaTraces supports other HTTP headers - see the list here .

The ingested trace spans can be queried according to these docs .

Collector configuration #

VictoriaTraces supports receiving traces from the following OpenTelemetry collector:

OpenTelemetry

OpenTelemetry #

To send the collected traces to VictoriaTraces, specify traces endpoint for OTLP/HTTP exporter in configuration file:

      exporters:
  otlphttp:
    traces_endpoint: http://<victoria-traces>:10428/insert/opentelemetry/v1/traces
    

VictoriaTraces supports various HTTP headers, which can be used during data ingestion - see the list here . These headers can be passed to OpenTelemetry exporter config via headers options. For example, the following configs add (or overwrites) foo: bar field to each trace span during data ingestion:

      exporters:
  otlphttp:
    traces_endpoint: http://<victoria-traces>:10428/insert/opentelemetry/v1/traces
    headers:
      VT-Extra-Fields: foo=bar
