Okay, I’ll rewrite the content as a bilingual technical blog post, following the structure, tone, formatting, and table requirements you specified.

OpenLIT: One-Click OpenTelemetry-Native Observability for Generative AI and LLMs

Introduction

OpenLIT allows you to simplify your AI development workflow, especially for Generative AI and LLMs. It streamlines essential tasks like experimenting with LLMs, organizing and versioning prompts, and securely handling API keys. With just one line of code, you can enable OpenTelemetry-native observability, offering full-stack monitoring that includes LLMs, vector databases, and GPUs. This enables developers to confidently build AI features and applications, transitioning smoothly from testing to production.

OpenLIT 能够简化你的 AI 开发工作流,尤其适用于生成式 AI 和大语言模型(LLM)。它优化了诸如使用 LLM 进行实验、组织和版本化管理提示词以及安全处理 API 密钥等关键任务。仅需一行代码,你便可开启基于 OpenTelemetry 的原生可观测性,提供涵盖 LLM、向量数据库和 GPU 的全栈监控。这让开发者能够自信地构建 AI 功能和应用程序,并平稳地从测试过渡到生产。

This project proudly follows and maintains the Semantic Conventions with the OpenTelemetry community, consistently updating to align with the latest standards in Observability.

该项目自豪地遵循并维护着与 OpenTelemetry 社区一致的语义约定,并持续更新以符合可观测性领域的最新标准。

Architecture Overview

The following flowchart illustrates the core data flow within the OpenLIT ecosystem.

以下流程图展示了 OpenLIT 生态系统中的核心数据流向。

flowchart TB;
    subgraph " "
        direction LR;
        subgraph " "
            direction LR;
            OpenLIT_SDK[OpenLIT SDK] -->|Sends Traces & Metrics| OTC[OpenTelemetry Collector];
            OTC -->|Stores Data| ClickHouseDB[ClickHouse];
        end
        subgraph " "
            direction RL;
            OpenLIT_UI[OpenLIT] -->|Pulls Data| ClickHouseDB;
        end
    end

The SDK sends telemetry data to the OpenTelemetry Collector, which then stores it in ClickHouse. The OpenLIT UI retrieves data from ClickHouse for visualization and analysis.

SDK 将遥测数据发送至 OpenTelemetry Collector,再由 Collector 将数据存储至 ClickHouseOpenLIT UI 从 ClickHouse 拉取数据以进行可视化和分析。


Getting Started with LLM Observability

Step 1: Deploy the OpenLIT Stack

  1. Clone the Repository

    克隆仓库

    Open your command line or terminal and run:

    git clone git@github.com:openlit/openlit.git
    
  2. Self-Host Using Docker

    使用 Docker 自行托管

    Deploy and run OpenLIT with:

    docker compose up -d
    

Note: For Kubernetes installation using Helm, refer to the Kubernetes Helm installation guide.

注意:如需在 Kubernetes 中使用 Helm 进行安装,请参阅 Kubernetes Helm 安装指南

Step 2: Install the OpenLIT SDK

Open your command line or terminal and run:

打开命令行或终端并运行:

pip install openlit

Note: For TypeScript SDK usage, visit the TypeScript SDK Installation guide.

注意:如需使用 TypeScript SDK,请访问 TypeScript SDK 安装指南

Step 3: Initialize OpenLIT in Your Application

Integrate OpenLIT into your AI applications by adding the following lines to your code.

将以下代码行添加至你的 AI 应用程序中,以集成 OpenLIT

import openlit

openlit.init()

Configure the telemetry data destination using the following parameters:

使用以下参数配置遥测数据的目标地址:

Purpose Parameter / Environment Variable For Sending to OpenLIT
Send data to an HTTP OTLP endpoint otlp_endpoint or OTEL_EXPORTER_OTLP_ENDPOINT "http://127.0.0.1:4318"
Authenticate telemetry backends otlp_headers or OTEL_EXPORTER_OTLP_HEADERS Not required by default

💡 Info: If otlp_endpoint or OTEL_EXPORTER_OTLP_ENDPOINT is not provided, the SDK outputs traces directly to the console—recommended during development.

💡 信息:如果未提供 otlp_endpointOTEL_EXPORTER_OTLP_ENDPOINT,SDK 将直接将链路追踪信息输出至控制台——推荐在开发阶段使用。

Example: Initialize Using Function Arguments

示例:使用函数参数进行初始化

import openlit

openlit.init(
  otlp_endpoint="http://127.0.0.1:4318",
)

Example: Initialize Using Environment Variables

示例:使用环境变量进行初始化

import openlit

openlit.init()

Then configure the OTLP endpoint via an environment variable:

然后通过环境变量配置 OTLP 端点:

export OTEL_EXPORTER_OTLP_ENDPOINT = "http://127.0.0.1:4318"

Step 4: Visualize and Optimize

With observability data now collected and sent to OpenLIT, the next step is to visualize and analyze this data. Access the OpenLIT UI at 127.0.0.1:3000 in your browser. Use the default credentials to log in:

随着可观测性数据被收集并发送至 OpenLIT,下一步是可视化和分析这些数据。在浏览器中访问 127.0.0.1:3000 以进入 OpenLIT UI,使用以下默认凭据登录:

  • Email: user@openlit.io
  • Password: openlituser
