Setup Sentry AI Agent Monitoring

Configure Sentry to track LLM calls, agent executions, tool usage, and token consumption.

Invoke This Skill When

• User asks to "monitor AI/LLM calls" or "track OpenAI/Anthropic usage"
• User wants "AI observability" or "agent monitoring"
• User asks about token usage, model latency, or AI costs

Important: The SDK versions, API names, and code samples below are examples. Always verify against docs.sentry.io before implementing, as APIs and minimum versions may have changed.

Prerequisites

AI monitoring requires tracing enabled (tracesSampleRate > 0).

Data Capture Warning

Prompt and output recording captures user content that is likely PII. Before enabling recordInputs/recordOutputs (JS) or include_prompts/send_default_pii (Python), confirm:

• The application's privacy policy permits capturing user prompts and model responses
• Captured data complies with applicable regulations (GDPR, CCPA, etc.)
• Sentry data retention settings are appropriate for the sensitivity of the data

Ask the user whether they want prompt/output capture enabled. Do not enable it by default — configure it only when explicitly requested or confirmed. Use tracesSampleRate: 1.0 only in development; in production, use a lower value or a tracesSampler function.

Detection First

Always detect installed AI SDKs before configuring:

# JavaScript
grep -E '"(openai|@anthropic-ai/sdk|ai|@langchain|@google/genai)"' package.json

# Python
grep -E '(openai|anthropic|langchain|huggingface)' requirements.txt pyproject.toml 2>/dev/null

Supported SDKs

JavaScript

*Vercel AI: 10.6.0+ for Node.js, Cloudflare Workers, Vercel Edge Functions, Bun. 10.12.0+ for Deno. Requires experimental_telemetry per-call.

Python

Integrations auto-enable when the AI package is installed — no explicit registration needed:

JavaScript Configuration

Node.js — auto-enabled integrations

Just ensure tracing is enabled. Integrations auto-enable when the AI package is installed:

Sentry.init({
  dsn: "YOUR_DSN",
  tracesSampleRate: 1.0, // Lower in production (e.g., 0.1)
  // OpenAI, Anthropic, Google GenAI, LangChain integrations auto-enable in Node.js
});

To customize (e.g., enable prompt capture — see Data Capture Warning):

integrations: [
  Sentry.openAIIntegration({
    // recordInputs: true,  // Opt-in: captures prompt content (PII)
    // recordOutputs: true, // Opt-in: captures response content (PII)
  }),
],

Browser / Next.js OpenAI (manual wrapping required)

In browser-side code or Next.js meta-framework apps, auto-instrumentation is not available. Wrap the client manually:

import OpenAI from "openai";
import * as Sentry from "@sentry/nextjs"; // or @sentry/react, @sentry/browser

const openai = Sentry.instrumentOpenAiClient(new OpenAI());
// Use 'openai' client as normal

LangChain / LangGraph (auto-enabled)

integrations: [
  Sentry.langChainIntegration({
    // recordInputs: true,  // Opt-in: captures prompt content (PII)
    // recordOutputs: true, // Opt-in: captures response content (PII)
  }),
  Sentry.langGraphIntegration({
    // recordInputs: true,
    // recordOutputs: true,
  }),
],

Vercel AI SDK

Add to sentry.edge.config.ts for Edge runtime:

integrations: [Sentry.vercelAIIntegration()],

Enable telemetry per-call:

await generateText({
  model: openai("gpt-4o"),
  prompt: "Hello",
  experimental_telemetry: {
    isEnabled: true,
    // recordInputs: true,  // Opt-in: captures prompt content (PII)
    // recordOutputs: true, // Opt-in: captures response content (PII)
  },
});

Python Configuration

Integrations auto-enable — just init with tracing. Only add explicit imports to customize options:

import sentry_sdk

sentry_sdk.init(
    dsn="YOUR_DSN",
    traces_sample_rate=1.0,  # Lower in production (e.g., 0.1)
    # send_default_pii=True,  # Opt-in: required for prompt capture (sends user PII)
    # Integrations auto-enable when the AI package is installed.
    # Only specify explicitly to customize (e.g., include_prompts):
    # integrations=[OpenAIIntegration(include_prompts=True)],
)

Manual Instrumentation

Use when no supported SDK is detected.

Span Types

Example (JavaScript)

await Sentry.startSpan({
  op: "gen_ai.request",
  name: "LLM request gpt-4o",
  attributes: { "gen_ai.request.model": "gpt-4o" },
}, async (span) => {
  span.setAttribute("gen_ai.request.messages", JSON.stringify(messages));
  const result = await llmClient.complete(prompt);
  span.setAttribute("gen_ai.usage.input_tokens", result.inputTokens);
  span.setAttribute("gen_ai.usage.output_tokens", result.outputTokens);
  return result;
});

Key Attributes

Enable prompt/output capture only after confirming with the user (see Data Capture Warning above).

Verification

After configuring, make an LLM call and check the Sentry Traces dashboard. AI spans appear with gen_ai.* operations showing model, token counts, and latency.
