Write line protocol using the influxdb3 CLI

Write line protocol data using the influxdb3 CLI

# Download sample data
curl -O https://docs.influxdata.com/downloads/home-sensor-data.lp \
&& \

influxdb3 write \
--database=home \
--file ./home-sensor-data.lp

Outputs the following:

Write line protocol using curl

Write line protocol data using curl and the InfluxDB HTTP API /api/v3/write endpoint (doesn't require a token):

response=$(curl --silent --write-out "%{response_code}:-%{errormsg}" \
  "http://0.0.0.0:8181/api/v3/write?database=home&precision=s" \
  --header "Content-Type: text/plain; charset=utf-8" \

Write line protocol from a compressed file using curl

Write line protocol from a compressed file using curl and the InfluxDB HTTP API /api/v3/write endpoint:

gzip ./home-sensor-data.lp home-sensor-data.gzip

response=$(curl --silent --write-out "%{response_code}:-%{errormsg}" \
  "http://0.0.0.0:8181/api/v3/write?database=home&precision=s" \

  --header "Content-Encoding: gzip" \
  --header "Accept: application/json" \
  --data=@home-sensor-data.gzip
)

# Format the response code and error message output.
response_code=${response%%:-*}
errormsg=${response#*:-}

# Remove leading and trailing whitespace from errormsg
errormsg=$(echo "${errormsg}" | tr -d '[:space:]')

echo "$response_code"
if [[ $errormsg ]]; then
  echo "$errormsg"
