NAME

       smemstat - report memory usage with shared memory divided proportionally

SYNOPSIS

       smemstat [options] [delay [count]]

DESCRIPTION

       smemstat reports the physical memory usage taking into consideration shared memory.

       Swap  reports  memory  that is swapped out to disk. Unshared memory is reported as USS (Unique Set Size).
       Unshared memory including the proportion of shared memory is reported as the PSS (Proportional Set Size).
       The non-swapped physical memory is reported as the RSS (Resident Set Size).

       Running  with  root  privilege  will report all user space processes, otherwise running without will just
       report the current user's processes.

       If a delay and count are not specified, a snapshot of the current memory used by the user's processes  is
       report.

       If  a  delay  in seconds is specified, smemstat will periodically show any per-process changes in memory;
       the interval being  the  specified  delay.   This  will  run  indefinitely  until  a  SIGINT  is  caught.
       Specifying count will repeat the periodic output count number of times.

OPTIONS

       smemstat options are as follow:

       -c     get command information from processes comm field

       -d     strip directory basename off command information

       -g     report memory in gigabytes

       -h     show help

       -k     report memory in kilobytes

       -l     show long (full) command information

       -m     report memory in megabytes

       -o file
              output data into a JSON formatted file

       -p proclist
              specify  a  comma separated list of processes to monitor. The process list may contain one or more
              PIDs or process names.

       -q     run quietly, only really makes sense with -o option

       -s     show short command information

       -t     top mode, show top changes of memory

       -T     top mode, show top consumers of memory
