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

NAME
XML::RSS::Headline::UsePerlJournals - XML::RSS::Headline Example Subclass VERSION
2.2 SYNOPSIS
You can also subclass XML::RSS::Headline to tweak the rss content to your liking. In this example. I change the headline to remove the date/time and add the Use Perl Journal author's ID. Also in this use Perl; rss feed you get the actual link to the journal entry, rather than the link just to the user's journal. (meaning that the journal URLs contain the entry's ID) use XML::RSS::Feed; use XML::RSS::Headline::UsePerlJournals; use LWP::Simple qw(get); my $feed = XML::RSS::Feed->new( name => "useperljournals", hlobj => "XML::RSS::Headline::UsePerlJournals", delay => 60, url => "http://use.perl.org/search.pl?tid=&query=&" . "author=&op=journals&content_type=rss", ); while(1) { $feed->parse(get($feed->url)); print $_->headline . " " for $feed->late_breaking_news; sleep($feed->delay); } Here is the output from rssbot on irc.perl.org in channel #news (which uses these modules) <rssbot> + [pudge] New Cool Journal RSS Feeds at use Perl; <rssbot> http://use.perl.org/~pudge/journal/21884 MUTAITED METHOD
$headline->item( $item ) Init the object for a parsed RSS item returned by XML::RSS. AUTHOR
