AI agents are proposed as future game-changers in observability and site reliability engineering (SRE), moving beyond dashboards and alerts to advanced reasoning with operational data. With recent advances in AI, companies like OpenAI show potential in LLMs taking actions on real-world data. This raises a debate if AI agents are just another wave of hype or if they will concretely improve aspects of SRE like incident response. Startups are emerging with various agentic solutions, while benchmarks like SREBench aim to evaluate their effectiveness.
