NAME

Linux::Statm::Tiny - simple access to Linux /proc/../statm

VERSION

version 0.0700

SYNOPSIS

  use Linux::Statm::Tiny;

  my $stats = Linux::Statm::Tiny->new( pid => $$ );

  my $size = $stats->size;

DESCRIPTION

This class returns the Linux memory stats from /proc/$pid/statm.

ATTRIBUTES

pid

The PID to obtain stats for. If omitted, it uses the current PID from $$.

page_size

The page size.

statm

The raw array reference of values.

size

Total program size, in pages.

vsz

An alias for "size".

Resident set size (RSS), in pages.

rss

An alias for "resident".

share

Shared pages.

text

Text (code).

lib

Library (unused in Linux 2.6).

data

dt

Dirty pages (unused in Linux 2.6).

ALIASES

You can append the "_pages" suffix to attributes to make it explicit that the return value is in pages, e.g. vsz_pages.

You can also use the "_bytes", "_kb" or "_mb" suffixes to get the values in bytes, kilobytes or megabytes, e.g. size_bytes, size_kb and size_mb.

The fractional kilobyte and megabyte sizes will be rounded up, e.g. if the "size" is 1.04 MB, then size_mb will return "2".

METHODS

refresh

The values do not change dynamically. If you need to refresh the values, then you you must either create a new instance of the object, or use the refresh method:

  $stats->refresh;
