Observability: Logging, Metrics, Tracing
Integrate comprehensive logging, metrics collection, and distributed tracing to gain deep insights into your LLM application's behavior.
What is Observability?
In this lesson, we'll explore observability, a crucial concept for managing complex software systems, especially LLM applications.
Observability means understanding the internal state of a system by examining the data it produces. Think of it as having X-ray vision into your application's behavior.
For LLM apps, this helps us answer critical questions like:
- Why is a request slow?
- Is the RAG retrieval working as expected?
- Are we incurring unexpected costs?
Logs: Recording Events
Logs are timestamped records of events that happen within your application. They are like a diary of your system's activities.
For LLM applications, logs are essential for:
- Tracking incoming user prompts.
- Storing responses from the LLM.
- Recording intermediate steps in a RAG pipeline (e.g., documents retrieved).
- Capturing errors or warnings.
They provide detailed contextual information for debugging and post-mortem analysis.
