smemstat - report memory usage with shared memory divided proportionally
smemstat reports the physical memory usage taking into consideration shared
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.
smemstat options are as follow:
- get command information from processes comm field
- strip directory basename off command information
- report memory in gigabytes
- show help
- report memory in kilobytes
- show long (full) command information
- 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.
- run quietly, only really makes sense with -o option
- show short command information
- top mode, show top changes of memory
- top mode, show top consumers of memory
