我如何使用一个 perl 脚本来创建/填充和绘制 RRDTool 图形

Question

这是一个示例：该脚本将生成数据。

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

my $i=0;
my $startTime=time;
$startTime += $ARGV[0] + 5;
my $dTime = localtime( $startTime );
print "\n##################\nLAUNCHING REQUESTS\n COUNT: $ARGV[0]\n DELAY: | 1 \nThe scripts will fire at : $dTime\n##################\n\n";
while ( $ARGV[0] > $i )
{
    $i++;
    system("php avtestTimed.php $ARGV[0] $ARGV[2] $startTime");
    print "RUN system('php avtestTimed.php $ARGV[0] $ARGV[2] $startTime'); \n";
    sleep 1;
}

标准输出上的结果是：

##################
LAUNCHING REQUESTS
 COUNT: 5
 DELAY: | 1 
The scripts will fire at : Mon Dec  6 09:38:15 2010
##################

现在我需要做的是获取两个变量： 1.执行于0.51596300 1291646308 2. 从 1.5987639427185 中 (https://test.yakabod.net/activityViewer/index.html) 收到的响应

并将其存储在 teo 变量中： $exec_at $receive_at 并使用这些值更新 RRDTool。 关于如何做到这一点的任何提示？我想要绘制的是： 1. EXECUTING AT 变量的线图 2.响应的散点图

谢谢， -卡迈勒。

您可以使用 CPAN 的 RRD::Simple要快速绘制此图：只需创建 rrd，并在每次迭代时调用更新您的数据点。您应该能够将链接上的示例改编为您的脚本。
