NAME

pcp-free - report on free and used memory in the system

SYNOPSIS

pcp free [-bkmgoltV] [-c count] [-s interval]

DESCRIPTION

pcp-free gives a summary display of the total amount of free and used physical memory and swap in the system, as well as the caches used by the kernel. When invoked via the pcp(1) command, the -h/--host, -a/--archive, -O/--origin, -s/--sam‐ ples, -t/--interval, -Z/--timezone and several other options become indirectly available. Options The -b/--bytes switch displays the amount of memory in bytes; the -k/--kilobytes switch (set by default) displays it in kilobytes; the -m/--megabytes switch displays it in megabytes. The -t/--total switch displays a line containing the totals. The -o switch disables the display of a "buffer adjusted" line. If the -o option is not specified, free subtracts buffer memory from the used memory and adds it to the free mem‐ ory reported. The -s/--interval switch activates continuous polling delay seconds apart. You may spec‐ ify any floating point number for delay, or indeed any valid pmParseInterval(3) specifica‐ tion, which includes microsecond resolution delay times. This can be used in conjunction with the -c/--samples option to terminate the display after count iterations. The -l switch shows detailed low and high memory statistics. The current version of pcp-free can be queried using the -V/--version option.

NOTES

pcp-free is inspired by the free(1) command and aims to be command line and output compat‐ ible with it. The shared memory column should be ignored; it is obsolete.
