サーバにinstallされているOSやMWの一覧を自動収集したい (centos版)

以下のように perl script書いて、実行したものを xymonあたりで収集すれば、OKな気がします

#!/usr/local/bin/perl
use strict;
use warnings;
use Data::Dumper;

my $OS_INFO_CMD = 'cat /etc/system-release';
my $RPM_LIST_CMD = 'rpm -aq';  # = yum list installed
my @SRC_LIST_CMDS =
    (["mysql",              "/usr/local/mysql/bin/mysql --version"],
     ["perl",               "/usr/local/bin/perl -v"],
     ["java",               "/usr/bin/java -version"],
     ["apache httpd",       "/home/end0tknr/local/apache24/bin/httpd -v"]);

main();
exit(0);

    my @sw_list;
    my $os_info  = installed_os_info();
    push(@sw_list,$os_info);

        print join("\t",@$sw_info),"\n";
    }
}

    my $fh;

    my $cmd = $OS_INFO_CMD;
    open($fh,"-|", $cmd) or die "fail open $cmd $!";
