Retell AI Observability

Overview

Implementation patterns for Retell AI observability — voice agent and telephony platform.

Prerequisites

• Completed retellai-install-auth setup

Instructions

Step 1: SDK Pattern

import Retell from 'retell-sdk';
const retell = new Retell({ apiKey: process.env.RETELL_API_KEY! });

const agents = await retell.agent.list();
console.log(`Agents: ${agents.length}`);

Output

• Retell AI integration for observability

Error Handling

Examples

Alert on a regression while protecting call content

Emit structured metrics for call completion, transfer outcome, latency, and provider errors using agent version and environment as bounded labels. When an alert fires, link the affected call identifiers to a restricted investigation record instead of attaching transcripts to the dashboard. Compare a synthetic call against the last known-good version, then make one reversible routing or configuration change and watch the same metrics through the defined recovery window.
