Beyond GPU Utilization: Exposing Hidden Performance Bottlenecks with Kernel Tracing

Traditional GPU dashboards measure utilization rates but miss the real culprits behind performance degradation—CPU scheduling conflicts, memory pressure, and I/O bottlenecks on the host side. eBPF kernel tracing bridges this gap by capturing causal chains between host-level events and GPU latency, enabling SREs to diagnose and resolve incidents in 60 seconds without waking engineering teams or restarting jobs.
