經常遇到一些需要監控的指標，從零開始做比較麻煩，借用cacti工具可以快速實現這類需求。
1、準備監控數據（可以5分鐘刷新一次）格式如下
a:100 b:100 c:100 d:100 e:100
2、準備perl腳本
get_content.pl
#!/usr/bin/perl
if (! eval "require LWP::UserAgent;")
{
$ret = "LWP::UserAgent not found";
}
if ( exists $ARGV[0]) {
if ($ret)
{
print "no ($ret)\n";
exit 1;
}
my $ua = LWP::UserAgent->new(timeout => 5);
my $response = $ua->request(HTTP::Request->new('GET',$ARGV[0]));
my @content = split (/\n/, $response->content);
print <span style="font-family: Arial, Helvetica, sans-serif;">$content[0]</span>;
print "\n";
}3、導入模板文件
