Session tracking in Netra provides powerful capabilities for monitoring user interactions and application behavior. This section covers how to track sessions, add custom context, and record events within your application.

​
Setting Up Session Tracking

Before you can start tracking sessions, initialize the Netra SDK: 
from netra import Netra
from netra.instrumentation.instruments import InstrumentSet

# Initialize with default settings
Netra.init(app_name="Your application name")

# Or with custom configuration
api_key = "Your API key"
headers = f"x-api-key={api_key}"
Netra.init(
    app_name="Your application name",
    headers=headers,
    trace_content=True,
    environment="Your Application environment",
	instruments={InstrumentSet.OPENAI}
)

​
Session Identification

Set unique identifiers for your sessions: 
# Set session identification
Netra.set_session_id("unique-session-id")
Netra.set_user_id("user-123")
Netra.set_tenant_id("tenant-456")

​
Custom Context Attributes

Add custom attributes to enrich your session data: 
# Add custom context attributes
Netra.set_custom_attributes(key="customer_tier", value="premium")
Netra.set_custom_attributes(key="region", value="us-east")
Netra.set_custom_attributes(key="plan_type", value="enterprise")

​
Custom Events

Record important events in your application: 
# Record user feedback event
Netra.set_custom_event(event_name="user_feedback", attributes={
    "rating": 5,
    "comment": "Great response!",
    "timestamp": "2024-01-15T10:30:00Z",
    "category": "positive"
})

# Record conversion event
Netra.set_custom_event(event_name="conversion", attributes={
    "type": "subscription",
    "plan": "premium",
    "value": 99.99,
    "currency": "USD",
    "source": "website",
    "campaign": "spring_sale"
})

# Record error event
Netra.set_custom_event(event_name="error_occurred", attributes={
    "error_type": "authentication",
    "error_message": "Invalid credentials",
    "severity": "high",
    "user_action": "login"
})
