[Epic] Evolution to AI-Native Observability: Integration of Hera Agent

[xs3508198]

Background

Standard observability platforms require manual dashboard checks and expert knowledge to identify root causes. To reduce the MTTR (Mean Time To Repair), we propose evolving Ozhera into an AI-Native platform.

Goal

Implement a conversational interface (Hera Agent) that can:

• Automatically summarize system health status.
• Perform root cause analysis (RCA) by querying metrics, logs, and traces.
• Execute maintenance tasks via predefined API interfaces (e.g., scale-up/down, log-level adjustment).

Key Components

• Integration with LLM frameworks (LangGraph/CrewAI).
• Asynchronous execution engine (Virtual Threads support).
• Natural language to PromQL/SQL translation.
