Overview ¶
Package otel exports spans and metrics to an OpenTelemetry collector using the OTLP HTTP/JSON protocol.
Use NewExporter to create an exporter, then chain its Exporter.ProcessEvent method with other exporters:
otelExporter := otel.NewExporter(ctx,
otel.WithEndpoint("http://localhost:4318"),
otel.WithServiceName("myservice"),
)
event.SetExporter(otelExporter.ProcessEvent)
The exporter batches telemetry and flushes periodically in a background goroutine. Call Exporter.Flush to force an immediate export.
