Sys::Statistics::Linux::ProcStats(3pm) User Contributed Perl Documentation Sys::Statistics::Linux::ProcStats(3pm)
NAME
Sys::Statistics::Linux::ProcStats - Collect linux process statistics.
SYNOPSIS
use Sys::Statistics::Linux::ProcStats;
my $lxs = Sys::Statistics::Linux::ProcStats->new;
$lxs->init;
sleep 1;
my $stat = $lxs->get;
Or
my $lxs = Sys::Statistics::Linux::ProcStats->new(initfile => $file);
$lxs->init;
my $stat = $lxs->get;
DESCRIPTION
Sys::Statistics::Linux::ProcStats gathers process statistics from the virtual /proc filesystem (procfs).
For more information read the documentation of the front-end module Sys::Statistics::Linux.
IMPORTANT
I renamed key "procs_blocked" to "blocked"!
LOAD AVERAGE STATISTICS
Generated by /proc/stat and /proc/loadavg.
new - Number of new processes that were produced per second.
runqueue - The number of currently executing kernel scheduling entities (processes, threads).
count - The number of kernel scheduling entities that currently exist on the system (processes, threads).
blocked - Number of processes blocked waiting for I/O to complete (Linux 2.5.45 onwards).
running - Number of processes in runnable state (Linux 2.5.45 onwards).
METHODS
new()
Call "new()" to create a new object.
my $lxs = Sys::Statistics::Linux::ProcStats->new;
Maybe you want to store/load the initial statistics to/from a file:
my $lxs = Sys::Statistics::Linux::ProcStats->new(initfile => '/tmp/procstats.yml');
If you set "initfile" it's not necessary to call sleep before "get()".
It's also possible to set the path to the proc filesystem.
Sys::Statistics::Linux::ProcStats->new(
files => {
# This is the default
path => '/proc',
loadavg => 'loadavg',
stat => 'stat',
}
);
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 $stat = $lxs->get;
raw()
Get raw values.
EXPORTS
No exports.
