NAME

Parse::Syslog::Line - Simple syslog line parser

VERSION

version 1.4

SYNOPSIS

I wanted a very simple log parser for network based syslog input. Nothing existed that simply took a line and returned a hash ref all parsed out.

use Parse::Syslog::Line qw(parse_syslog_line);

$Parse::Syslog::Line::DateTimeCreate = 1;

my $href = parse_syslog_line( $msg );
#
# $href = {
#       preamble        => '13',
#       priority        => 'notice',
#       priority_int    => 5,
#       facility        => 'user',
#       facility_int    => 8,
#       date            => 'YYYY-MM-DD',
#       time            => 'HH::MM:SS',
#       datetime_str    => 'YYYY-MM-DD HH:MM:SS',
#       datetime_obj    => new DateTime(), # If installed
#       datetime_raw    => 'Feb 17 11:12:13'
#       date_raw        => 'Feb 17 11:12:13'
#       host_raw        => 'hostname',  # Hostname as it appeared in the message
#       host            => 'hostname',  # Hostname without domain
#       domain          => 'blah.com',  # if provided
#       program_raw     => 'sshd(blah)[pid]',
#       program_name    => 'sshd',
#       program_sub     => 'pam_unix',
#       program_pid     => 20345,
#       content         => 'the rest of the message'
#       message         => 'program[pid]: the rest of the message',
#       message_raw     => 'The message as it was passed',
# };
...

FUNCTIONS

parse_syslog_line

Returns a hash reference of syslog message parsed data.

preamble_priority

Takes the Integer portion of the syslog messsage and returns a hash reference as such:

$prioRef = {
    'preamble'  => 13
    'as_text'   => 'notice',
    'as_int'    => 5,
};

preamble_facility

Takes the Integer portion of the syslog messsage and returns a hash reference as such:

$facRef = {
    'preamble'  => 13
    'as_text'   => 'user',
    'as_int'    => 8,
};
