UPDATE

hobbes3 (Jan 2018): This and the TA are modified copies of the original app built by Julien Ruaux and are compatible with a distributed Splunk environment. The original app is hosted at https://splunkbase.splunk.com/app/3077/.

NDBC Add-on

Splunk add-on for National Data Buoy Center observations

Installation

Install this add-on the same way you would install any Splunk app:

• automatically from SplunkBase through Browse more apps
• manually: download the ndbc.spl file and install it in your instance

Configuration

• Configure NDBC Data Inputs: Settings > Data Inputs > NDBC
• Enable the zones that would you like to receive buoy data from
• Alternatively, create a new data input with your own list of station identifiers

Marine Data

The NDBC add-on fetches data from NOAA's NDBC stations. It uses data available from this URL: http://www.ndbc.noaa.gov/get_observation_as_xml.php?station={station_id} and produces JSON documents with sourcetype ndbc.

Example of data returned by NDBC station 46025:

<observation id="46025" name="Santa Monica Basin - 33NM WSW of Santa Monica, CA" lat="33.749" lon="-119.053">
	<datetime>2016-03-04T20:50:00UTC</datetime>
	<winddir uom="degT">100</winddir>
	<windspeed uom="kt">1.9</windspeed>
	<windgust uom="kt">5.8</windgust>
	<waveht uom="ft">5.9</waveht>
	<domperiod uom="sec">16</domperiod>
	<avgperiod uom="sec">9.5</avgperiod>
	<meanwavedir uom="degT">272</meanwavedir>
	<pressure uom="in" tendency="falling">30.00</pressure>
	<airtemp uom="F">60.4</airtemp>
	<watertemp uom="F">62.4</watertemp>
	<dewpoint uom="F">51.4</dewpoint>
</observation>
