Understanding Linux PSI: Pressure Stall Information for System Resource Monitoring

Pressure Stall Information (PSI) is a Linux kernel feature that measures real‑time CPU, memory, and I/O pressure by tracking task wait times, offering finer granularity than load average or vmpressure, and enabling more accurate scheduling, cgroup management, and out‑of‑memory handling.
