MEMORY_PRESSURE(1) General Commands Manual MEMORY_PRESSURE(1)
memory_pressure – Tool to apply real or simulate memory pressure on the
memory_pressure [-l level] | [-p percent_free] | [-S -l level]
-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
-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.
