Full Discussion: per-process swap usage?
Top Forums UNIX for Advanced & Expert Users per-process swap usage? Post 302231544 by bukzor on Tuesday 2nd of September 2008 02:49:04 PM

As an aside, the 'ps' manpage documents the 'v' option as giving a virtual memory format, but doesn't document the fields presented. Can anyone tell me what these things mean? MAJFL is the major page fault count, I believe, and RSS is the "resident set size" meaning physical memory used, but what is "DRS"?

$ps v
PID TTY STAT TIME MAJFL TRS DRS RSS %MEM COMMAND
22511 pts/2 Ss 0:00 0 319 17576 3080 0.0 -tcsh
27192 pts/2 R+ 0:00 0 74 8261 728 0.0 ps v



In the meantime, I've tried using the "size" output from ps, since it seems most accurate (see original post), but I've hit a snag in that the number is many times too large for a couple types of processes (wine-preloader and java).

Examples:
Code:
wine-preloader(21951):
        PS:     rss:484.0       vsize:2367920.0 size:2345200.0  sz:591980.0
        TOP:    rss:480.0       vsize:872.0     share:476.0
wine-preloader(6990):
        PS:     rss:1300.0      vsize:2367924.0 size:2345204.0  sz:591981.0
        TOP:    rss:1292.0      vsize:1292.0    share:888.0
wine-preloader(24682):
        PS:     rss:452.0       vsize:2367912.0 size:2345192.0  sz:591978.0
        TOP:    rss:448.0       vsize:832.0     share:444.0

java(24885):
        PS:     rss:636.0       vsize:680912.0  size:634740.0   sz:170228.0
        TOP:    rss:620.0       vsize:10088.0   share:388.0
java(19015):
        PS:     rss:42336.0     vsize:1253548.0 size:1197556.0  sz:313387.0
        TOP:    rss:41984.0     vsize:42324.0   share:14836.0
