MEMORY_PRESSURE(1)           General Commands Manual          MEMORY_PRESSURE(1)

NAME
     memory_pressure – Tool to apply real or simulate memory pressure on the
     system

SYNOPSIS
     memory_pressure [-l level] | [-p percent_free] | [-S -l level]

OPTIONS
     -l <level> Apply real or simulate memory pressure (if specified alongside
     simulate argument) on the system till low memory notifications
     corresponding to <level> are generated.  Supported values are "warn" and
     "critical".

     -p <percent_free> Allocate memory till the available memory in the system
     is <percent_free> of total memory.  If the percentage of available memory
     to total memory on the system drops, the tool will free memory till either
     the desired percentage is achieved or it runs out of memory to free.

     -S Simulate memory pressure on the system by placing it artificially for
     <sleep_seconds> duration at the "warn" or "critical" level.

     -s <sleep_seconds> Duration to wait before allocating or freeing memory if
     applying real pressure.  In case of simulating memory pressure, this is the
     duration the system will be maintained at an artifical memory level.

DESCRIPTION
     A tool to apply real or simulate memory pressure on the system
