Quick Start

1. Install the SDK:

pip install observicia

2. Create a configuration file (observicia_config.yaml):

service_name: my-service
otel_endpoint: http://localhost:4317
opa_endpoint: http://localhost:8181/
policies:
  - name: pii_check
    path: policies/pii
    description: Check for PII in responses
    required_trace_level: enhanced
    risk_level: high
logging:
  file: "app.json"
  telemetry:
    enabled: true
    format: "json"
    redis:
      enabled: true
      host: "localhost"
      port: 6379
      db: 0
      key_prefix: "observicia:telemetry:"
      retention_hours: 24
  messages:
    enabled: true
    level: "INFO"
  chat:
    enabled: true
    level: "both"
    file: "chat.log"

3. Initialize in your code:

from observicia import init
from observicia.core.context_manager import ObservabilityContext

# Required - Initialize Observicia
init()

# Optional - Set user ID for tracking
ObservabilityContext.set_user_id("user123")

# Optional - Start a conversation transaction
transaction_id = ObservabilityContext.start_transaction(
    metadata={"conversation_type": "chat"}
)

# Use with OpenAI
from openai import OpenAI
client = OpenAI()
response = client.chat.completions.create(
    model="gpt-4",
    messages=[{"role": "user", "content": "Hello!"}]
)

# Or use with Ollama
import ollama
response = ollama.chat(
    model="llama2",
    messages=[{"role": "user", "content": "Hello!"}]
)

# Optional - End the transaction
ObservabilityContext.end_transaction(
    transaction_id,
    metadata={"resolution": "completed"}
)
