Multiple Concurrent Traces
This example demonstrates how to run multiple traces (sessions) concurrently using both the modern trace-based API and the legacy session API for backwards compatibility. First let’s install the required packages:- 
Create an environment variable in a .env file or other method. By default, the AgentOps init()function will look for an environment variable namedAGENTOPS_API_KEY. Or…
- 
Replace <your_agentops_key>below and pass in the optionalapi_keyparameter to the AgentOpsinit(api_key=...)function. Remember not to commit your API key to a public repo!
Modern Trace-Based Approach
The recommended approach usesstart_trace() and end_trace():
LLM Calls with Automatic Tracking
With the modern implementation, LLM calls are automatically tracked without needing special session assignment:Using Context Managers
You can also use traces as context managers for automatic cleanup:Using Decorators
For even cleaner code, use decorators:Legacy Session API (Backwards Compatibility)
For backwards compatibility, the legacy session API is still available:Ending Traces
End traces individually or all at once:Key Differences from Legacy Multi-Session Mode
- No mode switching: You can create multiple traces without entering a special “multi-session mode”
- Automatic LLM tracking: LLM calls are automatically associated with the current execution context
- No exceptions: No MultiSessionExceptionor similar restrictions
- Cleaner API: Use decorators and context managers for better code organization
- Backwards compatibility: Legacy session functions still work for existing code
