OpenWeather needs you to use an API key since Oct 9 2015. Therefore I added env.apikey. To get a key just register at OpenWeather.

# Steve Schnepp

|
|
# This part is taken from the original plugin
|
|
# Example usage:
|
|
# Do
|
|
# ln -s /path/to/openweather_ openweather_<query_string>
|
|
# where <query_string> is either a search query "q_Paris" or
|
|
# or an id search "id_2988507"
|
|
#
|
|
# These parameters translate directly into a URL formed like this:
|
|
# http://api.openweathermap.org/data/<api>/weather?<query_string>
|
|
#
|
|
|
|
## From Oct 9 2015 OpenWeather needs you to register and get an APIKEY
|
|
# include this key by setting 'env.apikey' in munin plugin config, i.e.:
|
|
# [openweather_*]
|
|
# env.apikey XYZ
