perl 获取监控数据(续)

上次的脚本只是将监控的数据展示在终端上，这次增加了一个功能：数据展示在终端的同时，存入到数据库中

code:

#!/usr/bin/perl -w

use strict;
use utf8;
use LWP::Simple;
use DBI;

my $dsn = 'DBI:mysql:database=monitor;host=localhost;port=3306';
my $dbh = DBI->connect($dsn,'root','test',{PrintError=>0,RaiseError=>1})
                        or die "Can't connect to mysql" . DBI->errstr;

my $table = qq/CREATE TABLE IF NOT EXISTS monitor (
               room char(20) not null,
               in_bytes varchar(100) not null,
               out_bytes varchar(100) not null,
               date timestamp not null
               )
              /;

my $sth = $dbh->prepare($table);
   $sth->execute();
   $sth->finish();

while (1) {
       my $url = shift || "http://xxx.xxx.xxx.xxx";
       my $content = get $url;
       my @url = split /\n/,$content;
       my ( $i,$str ) = ( 0,\@url );
       print scalar localtime,"\n";

       while ( $i < scalar @$str ) {

             if ( @$str[$i++] =~ /杭州机房1|杭州机房2|上海机房1|上海机房2/ ) {
                 binmode STDOUT,'encoding(utf8)';
                 my $room = $&;
                 print STDOUT "$&\n";
                 $i += 16;
                 my ($in) = @$str[$i++] =~ /(?:.*)\>(\S*\s*\S*).*\<\/td\>/;
                 printf '%s',"\tCurrent In: $1\t";
                 $i += 5;
                 my ($out) = @$str[$i++] =~ /(?:.*)\>(\S*\s*\S*).*\<\/td\>/;
                 printf '%s',"Current Out: $1\n\n";
                 my ($sec,$min,$hour,$day,$month,$year) = (localtime(time))[0..5];
                 $month++;$year+=1900;
                 my $date = sprintf "%04d-%02d-%02d %d:%d:%d",$year,$month,$day,$hour,$min,$sec;

                 my $data = qq/INSERT INTO monitor VALUES
                              ("$room","$in","$out","$date")/;
                    $sth = $dbh->do($data);
             }

       }

print '-' x 70,"\n";
sleep 900;

}

$dbh->disconnect();

代码有些改动，主要是之前的一些写法不太好。
