[Freifunk Franken] Routerstatistik, starke Schwankung

Sa Jan 7 10:23:33 CET 2017

Hallo zusammen,

ich habe mal ein kleines Script geschrieben, welches den Content 
herunterlädt und jeden Eintrag in eine gz-Datei schreibt:

use strict;
use warnings;
use LWP::UserAgent;
use Path::Tiny;

my %data_of = LWP::UserAgent
     ->new
->get('https://dev.freifunk-franken.de/christiandr/1483647698.alfred')
     ->content =~ m{ ["] ( (?: \\" | [^"] )+ ) ["] }xmsg;
for ( keys %data_of ) {
     $data_of{$_} =~ s{ \\x ( [[:xdigit:]]{2} ) }{ pack q{C}, hex $1 }xmsge;
     $data_of{$_} =~ s{ \\ (.) }{$1}xmsg;
     ( my $name = $_ ) =~ tr{:}{-};
Path::Tiny->new("C:/srv/workspace/$name.gz")->spew_raw( $data_of{$_} );
}

Und das stand dann im File f8-1a-67-a6-05-4e.gz
