proc_pid_statm(5) File Formats Manual proc_pid_statm(5)
NAME
/proc/pid/statm - memory usage information
DESCRIPTION
/proc/pid/statm
Provides information about memory usage, measured in pages. The
columns are:
size (1) total program size
(same as VmSize in /proc/pid/status)
resident (2) resident set size
(inaccurate; same as VmRSS in /proc/pid/status)
shared (3) number of resident shared pages
(i.e., backed by a file)
(inaccurate; same as RssFile+RssShmem in
/proc/pid/status)
text (4) text (code)
lib (5) library (unused since Linux 2.6; always 0)
data (6) data + stack
dt (7) dirty pages (unused since Linux 2.6; always 0)
Some of these values are inaccurate because of a kernel-internal
scalability optimization. If accurate values are required, use
/proc/pid/smaps or /proc/pid/smaps_rollup instead, which are
much slower but provide accurate, detailed information.
