OpenObserve Telemetry SDK

A simple and lightweight Python SDK for exporting OpenTelemetry logs, metrics, and traces to OpenObserve.

Features

• Easy Integration – Minimal setup with automatic instrumentation for popular libraries
• Multi-Signal Support – Capture logs, metrics, and traces simultaneously
• Flexible Protocol – Choose between HTTP/Protobuf (default) or gRPC
• Lightweight – Minimal dependencies, designed for production use
• OpenTelemetry Native – Built on OpenTelemetry standards for compatibility

Quick Start

Generate auth token:

echo -n "root@example.com:Complexpass#123" | base64
# Output: cm9vdEBleGFtcGxlLmNvbTpDb21wbGV4cGFzcyMxMjM=

Set environment variables:

# OpenObserve Configuration (Required)
export OPENOBSERVE_AUTH_TOKEN="Basic cm9vdEBleGFtcGxlLmNvbTpDb21wbGV4cGFzcyMxMjM="

# Optional OpenObserve settings (defaults shown)
export OPENOBSERVE_URL="http://localhost:5080"
export OPENOBSERVE_ORG="default"

# API keys for services you're using (optional, based on instrumentation)
export OPENAI_API_KEY="your-openai-key"
export ANTHROPIC_API_KEY="your-anthropic-key"

Install dependencies:

pip install openobserve-telemetry-sdk openai opentelemetry-instrumentation-openai

Quick Example – OpenAI Instrumentation:

from opentelemetry.instrumentation.openai import OpenAIInstrumentor
from openobserve import openobserve_init

# Initialize OpenObserve and instrument OpenAI
OpenAIInstrumentor().instrument()
openobserve_init()

from openai import OpenAI

# Use OpenAI as normal - traces are automatically captured
client = OpenAI()
response = client.chat.completions.create(
    model="gpt-3.5-turbo",
    messages=[{"role": "user", "content": "Hello!"}]
)
print(response.choices[0].message.content)

Quick Example – Anthropic Instrumentation:

from opentelemetry.instrumentation.anthropic import AnthropicInstrumentor
from openobserve import openobserve_init

# Initialize OpenObserve and instrument Anthropic
AnthropicInstrumentor().instrument()
openobserve_init()

from anthropic import Anthropic

# Use Claude as normal - traces are automatically captured
client = Anthropic()
response = client.messages.create(
    model="claude-3-5-sonnet-20241022",
    max_tokens=1024,
    messages=[{"role": "user", "content": "Hello!"}]
)
print(response.content[0].text)

Selecting Signals

By default, openobserve_init() initializes all signals (logs, metrics, traces). You can also initialize selectively:

# All signals (default)
openobserve_init()

# Specific signals only
openobserve_init(logs=True)
openobserve_init(metrics=True)
openobserve_init(traces=True)

# Combine signals
openobserve_init(logs=True, metrics=True)  # no traces

Note: For logs, you still need to bridge Python's standard logging module:

import logging
from opentelemetry.sdk._logs import LoggingHandler

openobserve_init(logs=True)
handler = LoggingHandler()
logging.getLogger().addHandler(handler)

Environment Variables

Protocol Configuration Notes

HTTP/Protobuf (default)

• Uses HTTP with Protocol Buffers encoding.
• Works with both HTTP and HTTPS endpoints.
• Organization is specified in the URL path: /api/{org}/v1/{signal}, where {signal} is traces, logs, or metrics.
• Automatically adds the stream-name header from OPENOBSERVE_TRACES_STREAM_NAME for traces and OPENOBSERVE_LOGS_STREAM_NAME for logs.
• Standard HTTP header handling (preserves case).

gRPC

• Uses gRPC protocol with automatic configuration:
  • Organization is passed as a header (not in the URL).
  • Automatically adds required headers:
    • organization: Set to OPENOBSERVE_ORG.
    • stream-name: Set to OPENOBSERVE_TRACES_STREAM_NAME for traces and OPENOBSERVE_LOGS_STREAM_NAME for logs.
  • Headers are normalized to lowercase per gRPC specification.
  • TLS is automatically configured based on URL scheme:
    • http:// URLs use insecure (non-TLS) connections.
    • https:// URLs use secure (TLS) connections.

Installation

Choose your preferred installation method:

# From PyPI (recommended)
pip install openobserve-telemetry-sdk

# From source (development)
pip install -e .

# Using requirements.txt
pip install -r requirements.txt

Both HTTP/Protobuf (default) and gRPC protocols are included in all installations.

Supported Instruments

The SDK works with OpenTelemetry instrumentation packages:

• OpenAI – Use with opentelemetry-instrumentation-openai for API call traces
• Anthropic – Use with opentelemetry-instrumentation-anthropic for Claude API traces
• LangChain – Use with opentelemetry-instrumentation-langchain for LLM chain tracing
• Standard Python Logging – Built-in support via LoggingHandler
• Metrics – OpenTelemetry counters, histograms, and up/down counters

Examples

Run any of these examples to see the SDK in action. First, ensure environment variables are set:

# Traces with OpenAI
python examples/openai_example.py

# Logs with standard Python logging
python examples/logs_example.py

# Metrics (counters, histograms, up/down counters)
python examples/metrics_example.py

# LangChain Q&A with session tracking
python examples/session_demo.py

See the examples/ directory for more samples including LangChain RAG chains and user tracking patterns.
