Quickstart

​

Introduction

1. Langtrace Cloud ☁️: Our managed SaaS solution for easy setup and immediate insights.
2. Self-hosted Langtrace 🏠: For organizations that prefer to host Langtrace on their own infrastructure.
3. OpenTelemetry Integration 🔗: Langtrace SDK supports sending traces to any OpenTelemetry-compatible backend (Datadog, New Relic, Grafana, etc), allowing you to use your existing observability stack.

​

Langtrace Cloud ☁️

1. Sign up by going to this link.
2. Create a new Project after signing up. Projects are containers for storing traces and metrics generated by your application. If you have only one application, creating 1 project will do.
3. Generate an API key. This key will be used to authenticate your application with Langtrace Cloud.
   You may also create new projects and generate API keys for each of them later.
4. In your application, install the Langtrace SDK. The code for installing the SDK is shown below:

// Install the SDK
npm i @langtrase/typescript-sdk

# Install the SDK
pip install langtrace-python-sdk

5. Initialize the Langtrace SDK with the API key you generated in the step 3. The code for setting up the SDK is shown below:

// Import it into your project. Must precede any llm module imports
import \* as Langtrace from '@langtrase/typescript-sdk'

Langtrace.init({ api_key: '<LANGTRACE_API_KEY>'})

# Import it into your project
from langtrace_python_sdk import langtrace # Must precede any llm module imports

langtrace.init(api_key = '<LANGTRACE_API_KEY>')

6. You can now use Langtrace in your code. Here’s a simple example:

from openai import OpenAI
client = OpenAI()

response = client.chat.completions.create(
model="gpt-3.5-turbo",
messages=[
{"role": "system", "content": "You are a helpful assistant."},
{"role": "user", "content": "Hello!"}
]
)
print(response.choices[0].message)

import OpenAI from 'openai';

const openai = new OpenAI();

async function main() {
  const completion = await openai.chat.completions.create({
    messages: [
      { role: 'system', content: 'You are a helpful assistant.' },
      { role: 'user', content: 'Hello!' }
    ],
    model: 'gpt-3.5-turbo',
  });

  console.log(completion.choices[0].message.content);
}

main();

​

OpenTelemetry Integration 🔗

1. Install the Langtrace SDK as described in the Langtrace Cloud section.
2. Instead of initializing with a Langtrace API key, configure the SDK to use your OpenTelemetry exporter. Refer to our documentation for OpenTelemetry tools. Or consult your platform of choice.
