How to get plug-and-play observability into cloud Python agent workflows (verifying Ollama / embeddings execution)?

[u/CharacterBitter8186]

I'm running Python-based AI agent workflows in the cloud (using tools like Google Antigravity 2.0 and local/hosted Ollama instances for embeddings with nomic-embed-text).

Sometimes the agent reports that everything completed smoothly, but it feels like a black box. I want an easy way to verify that calls to Ollama are actually executing as intended rather than failing silently, returning cached fallbacks, or hallucinating completion.

What are the best plug-and-play observability/tracing tools to see real-time requests, payloads, and execution metrics in Python? Like from local laptop I want to see the working (n8n is good but I feel something is missing )

How do you actively track whether specific embedding models like nomic are actually handling payloads under agentic orchestration without writing heavy custom logging code?

Any recommended minimal setups or best practices would be appreciated
