ArizeExporter

Sends Tracing data to Arize Phoenix, Arize AX, or any OpenTelemetry-compatible observability platform that supports OpenInference semantic conventions.

Constructor​

new ArizeExporter(config: ArizeExporterConfig)

ArizeExporterConfig​

type ArizeExporterConfig = Omit<OtelExporterConfig, 'provider'> & {
  // Phoenix / OpenTelemetry configuration
  endpoint?: string;
  apiKey?: string;

  // Arize AX configuration
  spaceId?: string;

  // Common configuration
  projectName?: string;
  headers?: Record<string, string>;
}

Inherits from OtelExporterConfig (excluding provider), which includes:

  • timeout?: number - Export timeout in milliseconds (default: 30000)
  • batchSize?: number - Number of spans per batch (default: 512)
  • logLevel?: LogLevel | 'debug' | 'info' | 'warn' | 'error' - Log level (default: WARN)
  • resourceAttributes?: Record<string, any> - Custom resource attributes

Methods​

exportTracingEvent​

async exportTracingEvent(event: TracingEvent): Promise<void>

Exports a tracing event to the configured endpoint.

export​

async export(spans: ReadOnlySpan[]): Promise<void>

Batch exports spans using OpenTelemetry with OpenInference semantic conventions.

shutdown​

async shutdown(): Promise<void>

Flushes pending data and shuts down the client.

Usage​

Phoenix Configuration​

import { ArizeExporter } from "@mastra/arize";

const exporter = new ArizeExporter({
  endpoint: "http://localhost:6006/v1/traces",
  apiKey: process.env.PHOENIX_API_KEY, // Optional for local Phoenix
  projectName: "my-ai-project",
});

Arize AX Configuration​

import { ArizeExporter } from "@mastra/arize";

const exporter = new ArizeExporter({
  spaceId: process.env.ARIZE_SPACE_ID!,
  apiKey: process.env.ARIZE_API_KEY!,
  projectName: "my-ai-project",
});

OpenInference Semantic Conventions​

The ArizeExporter implements OpenInference Semantic Conventions for generative AI applications, providing standardized trace structure across different observability platforms.
