get_session_details
Retrieve detailed session information from Langfuse observability, including observations with system prompts and model parameters, in compact or full JSON formats.
Instructions
Get detailed information about a specific session.
Args:
ctx: Context object containing lifespan context with Langfuse client
session_id: The ID of the session to retrieve (unique identifier string)
include_observations: If True, fetch and include the full observation objects instead of just IDs.
Use this when you need access to system prompts, model parameters, or other details stored
within observations. Significantly increases response time but provides complete data.
output_mode: Controls the output format and detail level
Returns:
Based on output_mode:
- compact: Summarized session details object
- full_json_string: String containing the full JSON response
- full_json_file: Summarized session details object with file save info
Usage Tips:
- For quick browsing: use include_observations=False with output_mode="compact"
- For full data but viewable in responses: use include_observations=True with output_mode="compact"
- For complete data dumps: use include_observations=True with output_mode="full_json_file"Input Schema
