Weather Data: Temperature, Windspeed, Humidity, Air Pressure

[blubbersuelze]

#######################################################################
#
# This Cacti Addon is for getting:
# - Temperature Data
# - Humidity
# - Wind Speed
# - Air Pressure
# from the Locations you'd want Monitor (maybe Server Locations)
# via Openweather graphed in Cacti
#
#######################################################################
1)
You need to have Python Modul 'simplejson' installed.

If you are not familiar with Python you have to do this
(based on a Debian System):

Code: Select all

apt-get install python-pip

2)
after this you have to do this:

Code: Select all

pip install simplejson

3)
now copy openweathermap_data.py to the scripts-Directory
(On Debian Systems it's in "/usr/share/cacti/site/scripts/" )

4)
import the Templates in Cacti with "Import Templates"

5)
The last point is an optical Feature, with CDEF-Functions for Temperature Graph

You have to create 2 easy CDEF Functions,
(maybe there will be an export Function for CDEF in future versions of Cacti too):

go to "Graph Management" -> CDEFs
click on "Add"

give the name "Greater 0" and click on Create
now click on Add
now do this:
Type: Special Data Source
Value: CURRENT_DATA_SOURCE
(Create)
Type: Custom String
Value: 0
(Create)
Type: Function
Value: MAX
now click on Save

NOW
click on "Graph Management" -> CDEFs again
(yes again, its for creating the second one)
click on "Add"

give the name "Lower 0" and click on Create
now click on Add
now do this:
Type: Special Data Source
Value: CURRENT_DATA_SOURCE
(Create)
Type: Custom String
Value: 0
(Create)
Type: Function
Value: MIN
now click on Save

DONE

USAGE:
Now when you select in Devices an Host click on "Create Graphs for this Host",
select in the Section "Graph Templates" (formally the first one) from the Selection Box "open Weather Map - <the Datatype you want to monitor>"
and click CREATE on the bottom of this Page,
you will be asked for City and Country to get the Temperatures.
(Maybe London uk, or Berlin de, or Paris fr ?)


Tip:
In the first minutes the Title in Graph Template seems to be incomplete.
I found out, if you've got some values in the Graph,
select the Open Weather Map - Graph Template in Graph Templates,
click on save,
now there should be the City and Country listed in the Graph like expected.


Have fun with this Cacti Addon

Thank for your sharing this!

Can you let us know where to apply the CDEF in which graphs? on all Min and Max ones?

here are some Pictures, i hope it will help to understand the written Description.

CDEF's can be handled here:

here you see greater 0 CDEF ready configured

here is the Line1 Configuration in Graph Template for Temperature with the CDEF Template:
(the CDEF Templates lower 0 and greater 0 are only needed at the Line-Graph's in the Temperature Template.)

You must use an API key for working
It's free
Then you change in script :
add a new variable
api ="&appid=xxxxxxxxxxxxxxxxxxxxxxxxx" where xxxxxxxxxx is your api key
and change
result = simplejson.load(urllib.urlopen(url + city + ',' + country + api))

[blubbersuelze]

you are right,

Openweather Map added a free Registration for the Usage of the API.

The Information to get a API Key can be found in the Script, where to place the Key also.

I updated the Script to handle the API Key.

This is not working at getting DATA from OpenWeathrMap in the latest version of Cacti!!!!!

[uclabsllc2018]

Had to completely rewrite the Python Script. Now it works as of 2022 !!

Can you share your Python Script,I have my api key but can't populate data.
Never mind like you said need to rewrite Python Script and set database for cacti but it is doable

Can you share the working script?

I've noticed the old script will no longer work with newer versions of python.

Unfortunately, they have monitized. You need to feed an API key. Simple change...

Too bad.
