Download and write to any InfluxDB installation the sample data used in Data Exploration, Schema Exploration, and Functions.
Download and write the data to InfluxDB
From your terminal, download the text file that contains the data in line protocol format:
curl https://s3-us-west-1.amazonaws.com/noaa.water.database.0.9/NOAA_data.txt > NOAA_data.txt
Write the data to InfluxDB via the CLI:
influx -import -path=NOAA_data.txt -precision=s

Data sources and things to note
The sample data is publicly available data from the National Oceanic and Atmospheric Administration’s (NOAA) Center for Operational Oceanographic Products and Services. The data include 15,258 observations of water levels (ft) collected every six seconds at two stations (Santa Monica, CA (ID 9410840) and Coyote Creek, CA (ID 9414575)) over the period from August 18, 2015 through September 18, 2015.
Note that the measurements average_temperature
, h2o_pH
, h2o_quality
, and h2o_temperature
contain fictional data.
Those measurements serve to illuminate query functionality in Schema Exploration.
The h2o_feet
measurement is the only measurement that contains the NOAA data.
Please note that the level description
field isn’t part of the original NOAA data - we snuck it in there for the sake of having a field key with a special character and string field values.
