The Pressure module reports Pressure Stall Information (PSI) collected for the cpu, memory, and io files/resources found in /proc/pressure. PSI metrics are included in Linux kernel versions from 4.20. Some distributions might have PSI support, but have disabled the feature via the CONFIG_PSI_DEFAULT_DISABLED setting, to enable PSI metrics pass psi=1 on the kernel command line during boot.
