Sys::Statistics::Linux::NetStats - Collect linux net statistics. use Sys::Statistics::Linux::NetStats; my $lxs = new Sys::Statistics::Linux::NetStats; $lxs->init; sleep 1; my $stats = $lxs->get; This module collects statistics by the virtual /proc filesystem (procfs) and is developed on default vanilla kernels. It is tested on x86 hardware with the distributions SuSE (SuSE on s390 and s390x architecture as well), Red Hat, Debian, Asianux, Slackware and Mandrake on kernel versions 2.4 and 2.6 and should run on all linux kernels with a default vanilla kernel as well. It is possible that this module doesn't run on all distributions if the procfs is too much changed. Further it is necessary to run it as a user with the authorization to read the /proc filesystem. It's necessary to initialize the statistics by calling "init()", because the statistics are deltas between the call of "init()" and "get()". By calling "get()" the deltas be generated and the initial values be updated automatically. This way making it possible that the call of "init()" is only necessary after the call of "new()". Further it's recommended to sleep for a while - at least one second - between the call of "init()" and/or "get()" if you want to get useful statistics. Generated by /proc/net/dev. rxbyt - Number of bytes received per second. rxpcks - Number of packets received per second. rxerrs - Number of errors that happend while received packets per second. rxdrop - Number of packets that were dropped per second. rxfifo - Number of FIFO overruns that happend on received packets per second. rxframe - Number of carrier errors that happend on received packets per second. rxcompr - Number of compressed packets received per second. rxmulti - Number of multicast packets received per second. txbyt - Number of bytes transmitted per second. txpcks - Number of packets transmitted per second. txerrs - Number of errors that happend while transmitting packets per second. txdrop - Number of packets that were dropped per second. txfifo - Number of FIFO overruns that happend on transmitted packets per second. txcolls - Number of collisions that were detected per second. txcarr - Number of carrier errors that happend on transmitted packets per second. txcompr - Number of compressed packets transmitted per second. ttbyt - Number of total bytes (received + transmitted) per second.

new()
Call "new()" to create a new object. my $lxs = new Sys::Statistics::Linux::NetStats;

init()
Call "init()" to initialize the statistics. $lxs->init;

get()
Call "get()" to get the statistics. "get()" returns the statistics as a hash reference. my $stats = $lxs->get; No exports. proc(5) Please report all bugs to <jschulz.cpan(at)bloonix.de>.
