InfluxDB 2.0 の Python Client の使い方です。

Ubuntu での準備

sudo apt install python-is-python3
sudo apt install python3-pip

organization: ekzemplaro
bucket: tochigi
としたサンプルです。

ライブラリーのインストール

pip3 install influxdb-client

トークンを調べる

influx auth list

データの書き込み

write_data.py

#! /usr/bin/python
#
#	write_data.py
#
#					Jul/07/2021
# ------------------------------------------------------------------
import influxdb_client
from influxdb_client.client.write_api import SYNCHRONOUS
# ------------------------------------------------------------------

bucket = "tochigi"
org = "ekzemplaro"
token = '1zIYs1taCm3pWQOBUNk0ssYccOF7YgJcdGyJDbiFYTBf7hcPvyl5nGyt71rNVkYtg2rBceUwQ1r5Xzm7Mabcde=='
#
url="http://localhost:8086"


client = influxdb_client.InfluxDBClient(
   url=url,
   token=token,
   org=org
)

write_api = client.write_api(write_options=SYNCHRONOUS)

pp = influxdb_client.Point("t0925") \
	.field("name", "日光") \
	.field("population", 23491) \
	.field("date_mod", "2004-6-14")
write_api.write(bucket=bucket, org=org, record=pp)
#
# ------------------------------------------------------------------

データの読み込み

query_data.py

#! /usr/bin/python
#
#	query_data.py
#
#						Jul/07/2021
# ------------------------------------------------------------------
import influxdb_client
from influxdb_client.client.write_api import SYNCHRONOUS

# ------------------------------------------------------------------
bucket = "tochigi"
org = "ekzemplaro"
token = '1zIYs1taCm3pWQOBUNk0ssYccOF7YgJcdGyJDbiFYTBf7hcPvyl5nGyt71rNVkYtg2rBceUwQ1r5Xzm7Mabcde=='
#
url="http://localhost:8086"

client = influxdb_client.InfluxDBClient(
   url=url,
   token=token,
   org=org
)

query_api = client.query_api()
query = ' from(bucket:"tochigi")\
|> range(start: -12h)'
result = client.query_api().query(org=org, query=query)
results = []
for table in result:
    for record in table.records:
        results.append((record.get_field(), record.get_value()))

print(results)
# ------------------------------------------------------------------

実行結果

$ ./query_data.py 
[('date_mod', '2004-6-14'), ('name', '日光'), ('population', 23491)]
