LlmLogObserver

class pipecat.observers.loggers.llm_log_observer.LLMLogObserver(*, name=None)

Bases: BaseObserver

Observer to log LLM activity to the console.

Logs all frame instances (only from/to LLM service) of:

• LLMFullResponseStartFrame

• LLMFullResponseEndFrame

• LLMTextFrame

• FunctionCallInProgressFrame

• LLMMessagesFrame

• OpenAILLMContextFrame

This allows you to track when the LLM starts responding, what it generates, and when it finishes.

Parameters:

name (str | None)

async on_push_frame(data)

Handle the event when a frame is pushed from one processor to another.

This method should be implemented by subclasses to define specific behavior (e.g., logging, monitoring, debugging) when a frame is transferred through the pipeline.

Parameters:

data (FramePushed) – The event data containing details about the frame transfer.
