NAME

memstat − print memory usage map

SYNTAX

memstat [ ifn ] [ interval ] [ corefile ] [ namelist ]

DESCRIPTION

The memstat program prints a map showing the utilization of all of memory.  The i key specifies that the printout should be repeated every interval seconds.  The f key causes corefile to be used as memory instead of /dev/mem.  The n key declares that the system namelist should be obtained from namelist instead of /unix.  Single or multiple options may be specified.  The arguments interval, corefile, and namelist must occur in the same order as the options [ifn]. 

The following headings appear on the memstat printout:

Addr Octal address range of the section of memory being mapped. 

Command
Name of the entity occupying a section of memory. This may be the operating system, a process, a shared text segment, or free memory.

Pid Process ID number of the process named in command. 

Size Total size in bytes of non-shared text processes or the size of the data segment of shared text processes. 

Ublock Address and size of the U block (per process data) for the process. 

Text Size and address of the processes text segment. 

Data Size and address of the processes data segment. 

Stack Size and address of the processes stack.
