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

Sampling Check

After detecting AI SDKs, check the current sampling configuration:

# JavaScript
grep -E 'tracesSampleRate|tracesSampler' sentry.*.config.* instrument.* src/instrument.* app/instrument.* 2>/dev/null

# Python
grep -E 'traces_sample_rate|traces_sampler' *.py **/*.py 2>/dev/null

If tracesSampleRate / traces_sample_rate is below 1.0 AND no tracesSampler / traces_sampler is configured:

Ask the user:

"Your current sample rate is {rate}. Agent runs are sampled as complete span trees — if the root span is dropped, all child gen_ai spans are lost. For full AI visibility, gen_ai-related transactions should be sampled at 100%. Would you like me to set up a tracesSampler that keeps AI traces at 100% while sampling other traffic at your current rate?"

If user confirms, read ${SKILL_ROOT}/references/sampling.md for implementation patterns.

Supported SDKs

JavaScript

Package	Integration	Min Sentry SDK	Auto?
openai	openAIIntegration()	10.28.0	Yes
@anthropic-ai/sdk	anthropicAIIntegration()	10.28.0	Yes
ai (Vercel)	vercelAIIntegration()	10.6.0	Yes*
@langchain/*	langChainIntegration()	10.28.0	Yes
@langchain/langgraph	langGraphIntegration()	10.28.0	Yes
@google/genai	googleGenAIIntegration()	10.28.0	Yes

*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:

Package	Auto?	Notes
openai	Yes	Includes OpenAI Agents SDK
anthropic	Yes
langchain / langgraph	Yes
huggingface_hub	Yes
google-genai	Yes
pydantic-ai	Yes
litellm	No	Requires explicit integration
mcp (Model Context Protocol)	Yes

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

op Value	Purpose
gen_ai.request	Individual LLM calls
gen_ai.invoke_agent	Agent execution lifecycle
gen_ai.execute_tool	Tool/function calls
gen_ai.handoff	Agent-to-agent transitions

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

Attribute	Description
gen_ai.request.model	Model identifier
gen_ai.request.messages	JSON input messages
gen_ai.usage.input_tokens	Input token count
gen_ai.usage.output_tokens	Output token count
gen_ai.agent.name	Agent identifier
gen_ai.tool.name	Tool identifier

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.

Troubleshooting

Issue	Solution
AI spans not appearing	Verify tracesSampleRate > 0, check SDK version
Token counts missing	Some providers don't return tokens for streaming
Prompts not captured	Enable recordInputs/include_prompts
Vercel AI not working	Add experimental_telemetry to each call
