how does this work with proxy server? I have a proxy server that requires authentication as well.

however, i dont even get error on command line:

[root@intranet scripts]# ./weatherbug.pl KEWR
[root@intranet scripts]#

Thanks!

Just as a test, it does work fine on my non-public server:

[jweinraub@rockhopper:~]
$ ./weatherbug.pl KEWR
Tries:1 Humidity:56.0 FeelsLike:22.8 Wind:14.8 DewPoint:13.8 Temp:22.8 Rain:0.00 Pressure:102.74

I ended up redoing the script a bit personally using ideas from the wxer - get much better values back from wunderground than weatherbug/aws.

if i export http_proxy with my credentials it works fine on my production web server on command line.

however, it doesnt work in script. is there a way to put these vars in the perl script itself?

[jweinraub]

okay i got it to work finally.

if anybody else is in my scenario this is what i did:

Code: Select all

#!/usr/bin/perl
use warnings;
#use strict;

use LWP::UserAgent;

$ua = LWP::UserAgent->new;
$ua->proxy(['http', 'ftp'] => 'http://jweinraub:password@proxy:8080');
# ... snip ...
 my $req = new HTTP::Request('GET', $httpaddr);
 $content = $ua->request($req)->as_string;

Found it!

Some of the variables like mph & "Hg that are used on the AWS site are hard-coded in weatherbug.pl.

The following alterations will make it work for the Metric system:

Code: Select all

my $httpaddr = "http://www.aws.com/aws_2001/asp/obsforecast.asp?units=1&id=" . $ARGV[0];

of course, but also:

Code: Select all

# regex in html source order                                                                                                                                
if ($_ =~ /Temperature\(\DC\)\s(-?\d+?\.\d+?)\s/g)    { $data{Temp} = $1; }                                                                                 
if ($_ =~ /Humidity\s\(\D\)\s(\d+?\.\d+?)\s/g)        { $data{Humidity} = $1; }                                                                             
if ($_ =~ /Wind\s\(kph\).+?(\d+?\.\d+?)\s/g)          { $data{Wind} = $1; }                                                                                 
if ($_ =~ /Daily\sRain\s\(cm\)\s(\d+?\.\d+?)\s/g)     { $data{Rain} = $1; }                                                                                 
if ($_ =~ /Pressure\s\(kPa\)\s(\d+?\.\d+?)\s/g)      { $data{Pressure} = $1; }                                                                              
if ($_ =~ /(HEAT INDEX|WIND CHILL):(\d+?\.\d+?)\s/g)  { $data{FeelsLike} = $2; }                                                                            
if ($_ =~ /DEW\sPOINT:\s(\d+?\.\d+?)\s/g)             { $data{DewPoint} = $1; }   

sorry sir!

can you explain me wich is the file that i have to change?

I made those changes and adjusted the Graph Templates as well.
I decided to use the METAR Code as a Hostname (e.g. EDDM for Munic Airport) to avoid being prompted for the METAR Code for each Graph Template. You will avoid entering a community string and this deactivates Host Availability checking.
I renamed the script to avoid misunderstanding.

Updated the XML for the Templates. Requires at least cacti 0.8.6j

Did anyone else's weather bug stop working?

[bort13]

Yep, aws.com has changed something, so you're not getting the page returned that the script is intending to parse.

[Smitty]

Yep, I thought that is what happened to it but just wanted to make sure it was not just me.

Thanks!

If you want to use a zip code, you can also use

Code: Select all

http://www.aws.com/obsforecast.asp?&zipcode=

[apperrault]

Does the zip code work for Canadian Zip codes as well? I am having a hell of a time locating the correct code for two of my offices in Canada.

just wondering if i could use this instead.

It does work, but I decided to use Environment Canada's Weather Office pages instead.

See the attached templates and perl script.

Works the same as the Weather Bug templates, except there's no Rainfall graph. I did however add a graph for 'visibility' as it's listed on the Weather Office pages.

To find your weather code, go to http://text.www.weatheroffice.gc.ca/canada_e.html and find the city you want to graph weather for.
Once you're at the page, copy the first argument to the page and use it as your location code.

For example, I'm in Ottawa, so my URL is:
http://text.www.weatheroffice.gc.ca/for ... 118&unit=m
This makes my Code: on-118

If you want Imperial units, change the last M to an I in the perl script and you're off to the races. You'll also have to change the legends and descriptors in the graphs to represent °F, MPH and wind speed and pressure.
