NAME

Linux::net::dev - Perl extension for parsing /proc/net/dev

SYNOPSIS

  use Linux::net::dev;
  my $devs = Linux::net::dev::info();
  print "Devices (bytes read):\n";
  foreach (keys %$devs) {
    print "  $_ ($devs->{$_}->{rbytes})\n";
  }

DESCRIPTION

Linux::net::dev parses /proc/net/dev for network devices statistics. The package contains these functions:

info

This function returns hash reference. Keys are devices' ids and values are data hash references. Data hash has resource names for keys and their respective values as associated values.

dev

Takes device id as a single argument and returns that device's data.

devs

Takes list of device ids as arguments and returns array with those devices' data.

Recognized resources (data hash keys): rbytes, rcompressed, rdrop, rerrs, rfifo, rframe, rmulticast, rpackets, tbytes, tcarrier, tcolls, tcompressed, tdrop, terrs, tfifo, tpackets,

Resources begining with "r" are values for read data, and those begining with "t" are values for transmited data.

Package was built and tested on RedHat 7.2, kernel 2.4.7-10 and might not work on some other versions. Please report bugs along with your kernel version (uname -r or uname -a).
