AccuWeather script & templates

[Alives]

This script monitors 22 different weather variables off the accuweather site. It is a standard perl html scraper script.

enjoy!

P.S. The results, as you can see, arent that accurate. I have another post with WeatherBug scrapes here: http://forums.cacti.net/viewtopic.php?p=38926 but its only 6 variables.

You need the LWP::Simple perl module installed

When I run the script from the command line as the cactiuser I get what looks like the proper output, howver when the poller runs it, it fails.

Command Line Output:
sh-3.00$ scripts/AccuWeather.pl b3l1s3
Dewpoint:25 Humidity:99 WindChill:27 Departure:22 LowPast6hrs:17 ApparentTemp:25 MaxTemp:22 CloudCover:100 MinTemp:25 HighPast6hrs:25


Poller Ouput:
08/09/2005 02:18:45 PM - CMDPHP: Poller[0] Host[115] DS[1404] WARNING: Result from CMD not valid. Partial Result:
08/09/2005 02:18:45 PM - CMDPHP: Poller[0] Host[115] DS[1404] CMD: perl /var/www/html/cacti/scripts/AccuWeather.pl b3l1s3, output: U

Note, that I had to change the URL in the script to make it work for Canada and to show metric.

yeah... try putting that in quotes or just hardcoding it to the script... your input uses the pipe, |, which i think your shell is trying to interpret. easiest thing to do is to just hard code your script since you probably dont need the flexibility too much...

Hi,
when I import the accuweather_template, Cacti says : Error: XML: Hash version does not exist.
My Cacti version is 0.8.6c
I don't find where is the bug ??

[_JPL_]

I couldn't import the file but I could copy/paste the contents of the file into the import area.

[Alives]

this was made using cacti 0.8.6f

I found a Hash error while importing into my cacti version f/// its on like line 112 , a variable RealFeel had the trademark symbol right after the work RealFeel, cacti or xml didnlt like that for me, i just removed it and saved the xml template and re-imported it// worked perfectly/

Anyone using this accuweather script??

Does anyone notice that the Humidity is always 50% /// I ran this script agains like 5 zipcodes, always 50 %. Has anyone noitced this, corrected it?? How??

THanks

[Alives]

accuweather isnt all that accurate...thats why i did the weatherbug script... its VERY accurate with live updating.

[spoonman]

I understand that but i dont think its accuweathers' site, I ran the script against 5 or so ziips. All said 50 % , even the pics in this thread say 50% for Humidity.....i think its the script?? I just dont see anything wrong right off, and i'm not the best with scripts or code?? Just was wondering if anyone had fixed that variable that pulls Humidity??

Thanks

[Alives]

it is the script... i would be honored if you would fix it as i am only working on the weatherbug one at this point. its just a simple regex, and, as many people will reply, you arent supposed to grab html pages with regex's... but whatever... it was quick adn easy

Calling all Perl Gurus' >> It seems to me the Accuweather scripts has a few flaws in it

if ($content =~ /(\d+)%/g) { $data{Humidity} = $1; }
if ($content =~ /(\d+)%/g) { $data{CloudCover} = $1; }

Those 2 are what I see wrong anyhow, no matter what zip you run the script against it pulls back 50% for Humidity and 99% for cloudcover. All the time!!! I think the search string above is messed up or something or its just finding the wrong data in the source of that web page. Its almost like its pulling back cell width % or something!!! Anyone feel like looking at it more to see if you see what's wrong??

Thanks all.

Change lines to these:
if ($content =~ /(\d+)%</g) { $data{Humidity} = $1; }
if ($content =~ /(\d+)%</g) { $data{CloudCover} = $1; }

[spoonman]

That did it, all variables now report the correct #'s !!! Thanks for that, I searched all kinds of regex characters and didnt' see that one, yet again i'm not a perl guy!! Thanks again!!!!

[spoonman]

Updated Accuweather perl script with corrected variables ( Humidity and CloudCover both reporting 50% for no matter what zip you add ) !! Thanks for the help zoltar!!!
