NAME

Sysstat::Sar - Sysstat sar file parser

VERSION

version 0.003

SYNOPSIS

    This module parse sar file output to perl data structure for easy manipulation.
    To turn on diagnostics, set SMART_COMMENTS=1 to environment variable.
    Some additional value is added like cpu min and max idle value for each day / all records in a day.

METHODS

check_header

    parameter (current line from file handle, hash reference )
    This method return a hash reference passed from parse method.

    it will set current position hostname, date, os, kernel version, cpu arch and totalcpu.
    hash structure that being setup are : 
    {hostname}{date}{os}
    {hostname}{date}{kernel}
    {hostname}{date}{arch}
    {hostname}{date}{totalcpu}

parse

    return parse output in hash
    structure :
    hostname->date->memory
                            ->detail    = array
                            ->average   = array
                            ->used->min = scalar
                            ->used->max = scalar

    hostname->date->cpu
                            ->'all/cpu number'              = array
                            ->idle->'all/cpu number'->min   = scalar
                            ->idle->'all/cpu number'->max   = scalar
                            ->average->'all/cpu number'     = array
