# OpenWeatherMap Input Plugin

Collect current weather and forecast data from OpenWeatherMap.

To use this plugin you will need an [api key][] (app_id).

City identifiers can be found in the [city list][]. Alternately you
can [search][] by name; the `city_id` can be found as the last digits
of the URL: <https://openweathermap.org/city/2643743>. Language
identifiers can be found in the [lang list][]. Documentation for
condition ID, icon, and main is at [weather conditions][].

## Global configuration options <!-- @/docs/includes/plugin_config.md -->

In addition to the plugin-specific configuration settings, plugins support
additional global and plugin configuration settings. These settings are used to
modify metrics, tags, and field or create aliases and configure ordering, etc.
See the [CONFIGURATION.md][CONFIGURATION.md] for more details.

[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md#plugins

## Configuration

```toml @sample.conf
# Read current weather and forecasts data from openweathermap.org
[[inputs.openweathermap]]
  ## OpenWeatherMap API key.
  app_id = "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"

  ## City ID's to collect weather data from.
  city_id = ["5391959"]

  ## Language of the description field. Can be one of "ar", "bg",
  ## "ca", "cz", "de", "el", "en", "fa", "fi", "fr", "gl", "hr", "hu",
  ## "it", "ja", "kr", "la", "lt", "mk", "nl", "pl", "pt", "ro", "ru",
  ## "se", "sk", "sl", "es", "tr", "ua", "vi", "zh_cn", "zh_tw"
  # lang = "en"

  ## APIs to fetch; can contain "weather" or "forecast".
  # fetch = ["weather", "forecast"]

  ## OpenWeatherMap base URL
  # base_url = "https://api.openweathermap.org/"

  ## Timeout for HTTP response.
  # response_timeout = "5s"

  ## Preferred unit system for temperature and wind speed. Can be one of
  ## "metric", "imperial", or "standard".
  # units = "metric"

  ## Style to query the current weather; available options
  ##   batch      -- query multiple cities at once using the "group" endpoint
  ##   individual -- query each city individually using the "weather" endpoint
  ## You should use "individual" here as it is documented and provides more
  ## frequent updates. The default is "batch" for backward compatibility.
  # query_style = "batch"

  ## Query interval to fetch data.
  ## By default the global 'interval' setting is used. You should override the
  ## interval here if the global setting is shorter than 10 minutes as
  ## OpenWeatherMap weather data is only updated every 10 minutes.
  # interval = "10m"
```

## Metrics

- weather
  - tags:
    - city_id
    - forecast
    - condition_id
    - condition_main
  - fields:
    - cloudiness (int, percent)
    - humidity (int, percent)
    - pressure (float, atmospheric pressure hPa)
    - rain (float, rain volume for the last 1-3 hours (depending on API response) in mm)
    - snow (float, snow volume for the last 1-3 hours (depending on API response) in mm)
    - sunrise (int, nanoseconds since unix epoch)
    - sunset (int, nanoseconds since unix epoch)
    - temperature (float, degrees)
    - feels_like (float, degrees)
    - visibility (int, meters, not available on forecast data)
    - wind_degrees (float, wind direction in degrees)
    - wind_speed (float, wind speed in meters/sec or miles/sec)
    - condition_description (string, localized long description)
    - condition_icon
