You must register for the WeatherBug API Code in order to use this template/script. This is a much better way of polling the weatherbug data and is approved by them.

Register for your API Code here: http://apireg.weatherbug.com/defaultAPI.aspx

Place the script in your cacti/scripts/ directory and make sure it is executable.

Do you have some instructions on how to actually set this up?

Ive registered and got my API code, what do i do with it?
How should the perl script be executed or is that done by the poller

running

perl weatherbug_api.pl
Use of uninitialized value in concatenation (.) or string at weatherbug_api.pl line 6.
Use of uninitialized value in concatenation (.) or string at weatherbug_api.pl line 6.

you arent running it correctly:

perl <path_cacti>/scripts/weatherbug_api.pl <api_code> <zipcode>

Is this script only for the US ?
I want to graph weather in Wellington NZ is this possible ?

Where abouts on the weatherbug website do i get the code?
I must be blind ! or its just friday !

Weatherbug for use where zipcode isnt available and/or using metric units:

Register for your API Code here: http://apireg.weatherbug.com/defaultAPI.aspx

You can do a cityCode lookup here:
http://{api code}.api.wxbug.net/getLocationsXML.aspx?ACode={api code}&SearchString={city name}

Example: http://A1111111111.api.wxbug.net/getLoc ... String=San Francisco

Just make sure you substitute in your api code that you received in email. This will return all the city codes found.

I have attached the new WeatherBug Metric template below and the weatherbug_api_metric.pl script below. You will need both of these to run the Metric mode using city code.

If you want to use english units and a city code, you just need to download the 2nd script called weatherbug_api.pl You do not need the template file for this to work. This script is to be used in place of the previous script in the first post. This script uses the template from the first post.

Place the script you are using in your <cacti path>/scripts/ directory and give it execute permissions.

Still wondering how you install this...

What do you enter it as (device, hostname?).. It's a little confusing..

Alives · Post by **Alives** » Fri Apr 18, 2008 5:32 pm

device and hostname are not important since they arent used to poll data.

for device, call it whatever you want. I call mine weatherbug.

for hostname, I just give it 127.0.0.1 so it wont complain about not being up.

I have setup script and pl file but graph don`t appear.

I post error code.

RRDTool Says:

ERROR: the RRD does not contain an RRA matching the chosen CF

I test metric and not metric script.

I testet with city code, and this code that I`ve posted is with non metric script and with zip code.

But the error is still there.

And for any graph that i make it collect all data as shown.

Ok
So ive setup a city and created all the graphs with the correct API code and City Code

How exactly should the perl script be executed ?
Should i execute it with the city code and API code at the command line to create the graphs?
Do i execute it every 1 minute 5 minutes via cron, or is the cacti poller going to do it for me ?

How is the data polled?
Shouldn't running the perl script create the graphs, or is that merely creating the data which then cacti's poller ( which should be running from cron every 5 minutes ) should pick up and create the rrd files ?

h2d · Post by **h2d** » Sat Apr 19, 2008 7:16 am

Also i notice when i do execute the perl script at the command prompt i get this
./weatherbug_api.pl A3451207554 W48564
Humidity:66

Only ever Humidity ?? Never any other stats ?

Alives · Post by **Alives** » Sat Apr 19, 2008 9:27 am

Sorry about that I had a typo in the metric script. Basically change the 0 in &unittype=0 to a 1: &unittype=1 on line 6, or re-download the script and it will work.

perl /tmp/weatherbug_api.pl A3451207554 W48564
DewPoint:24 Temp:27.0 Humidity:83 Wind:5 FeelsLike:31 Rain:0.0 Pressure:1008.13

Sorry about that

It should work now if you re-download the script. Also, you do not execute these scripts by hand. Cacti does it through the data input methods.

How do you set this up to do multiple cities/areas?

I want to monitor the areas where my routers and servers are.
