How to track token usage and cost across models and users
How to debug using prompt and response logs
How to use waterfall views and span details for analysis

How to use dashboards for LLM cost monitoring
This video explores why modern AI applications-especially those using multiple LLMs, large context windows, and tool integrations-require strong observability to ensure reliability and efficiency. It introduces the four key monitoring signals: traces, latency, token usage/cost, and logs.
The tutorial walks through instrumenting an LLM application using OpenTelemetry GenAI specifications and integrating it with OpenObserve via a Python SDK or collector. Using real-world trace data from a production SRE agent, the video demonstrates how to analyze system performance through metrics like request rate, errors, and duration.
It further showcases advanced visualization tools including waterfall trace views, span-level input/output inspection, flame graphs for identifying bottlenecks, service maps, and DAG flow diagrams. The video also highlights how logs and metrics can be correlated using trace IDs, and presents pre-built dashboards for tracking LLM costs across models, users, and features.
