In high-performance computing (HPC) environments, the need for robust observability mechanisms is critical to ensure optimal performance, fault tolerance, and resource utilization. Airgapped systems, often used in sensitive or high-security domains, require innovative solutions to capture, analyze, and visualize system metrics, application performance, and infrastructure health without compromising security.

Challenges arise in airgapped HPC environments, where network isolation adds complexity to monitoring and diagnostics. I explore methodologies for establishing observability in airgapped HPC environments, focusing on the unique challenges of data collection, real-time monitoring, and offline analytics. Additionally, I discuss the role of automated anomaly detection, resource optimization, and performance tuning in maintaining the efficiency and reliability of these systems. The findings highlight the importance of maintaining a balance between high security and comprehensive observability, paving the way for more resilient and performant airgapped HPC environments.
