SCRIPT
The script takes the same arguments, just the weather site code from the URL ( http://www.aws.com/aws_2001/asp/obsforecast.asp?id= ). If you want metric, alter the URL.

You need to set the timeout values in the script by hand.
$timeout is the time in seconds that each http get request will timeout.
$total_time is the total amount of time the script will try to get the data. If this total time is reached, the script exits.

** It is important that you keep in mind the value in the console settings under poller that determines how long cacti pollers will wait for script data. The default is 25 I think. You can play around with this, but keep in mind that all of your polling must finish within 5 minutes (300 seconds) in order for cacti to be working properly. **

The script now outputs the number of tries that it takes to get the weather data. I was using this for debugging purposes, but it seems somewhat useful to determine if the weather station you chose sucks or not.

GRAPHS
Not much new here. There is a new graph called Tries that shows the number of tries it took the script to pull the weather data.

Trendlines (CDEF) have been added to wind and tries to give a better understanding of what is going on.


I have exported my host template which includes all dependencies.

This host template was exported from 0.8.6h so it should work for you unless you are a couple versions behind.

Graphs...

[Alives]

I just got some downtime in my graphs... the website www.aws.com was actually down... oh well.

[evert]

What is the recommended/only way to upgrade from version 1.x to 2.0?

[Alives]

If you dont need the new graphs, which didnt change that much, you can just replace the script. Comment out or delete line 25,

Code: Select all

$data{Tries} = $tries;

and it should be just fine. Just make sure you have www::mechanize installed. Give it a test on the command line first.

[Smitty]

Can anyone help me install the WWW::Mechanize with yum?

Thanks Alives for bring this back, just hope I can figure this WWW::Mechanize out so I can use it.

Thanks everyone!

[Alives]

I'll try to rewrite it so it uses LWP::Simple

[evert]

Hmm, looks like my cacti is not getting all values needed...

Here is an output of weatherbug.pl KJFK:

Code: Select all

DewPoint:10.9 Tries:1 Humidity:63.7 FeelsLike:17.7

Why are the other values not returned? I am using the units=1 setting, but that shouldn't block them, right?

[evert]

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

[Alives]

ah yes, sorry about that i didnt consider people would want metric. You will want to adjust some of the graph ranges too probably

[streaker69]

Ok, I give up, I believe I have WWW::Mechanize installed properly, but the script isn't working. Below is what I get if I try to run the script from the command line

Any ideas?

[Alives]

I have reposted the script. Re-download it and it will work. Uses LWP::Simple again so you shouldnt need to install anything extra out of the box.

Thanks, works great now.

Is that version better than the Mechanize one? Should I switch?

BTW, not always accurate/complete, the info from AWS...

http://www.aws.com/aws_2001/asp/obsFore ... RY&units=1 says it is dry. It's been raining for hours now...
