pyinflux3 0.9.2

Community Python client for InfluxDB IOx

About

This is a community repository of Python code for InfluxDB with IOx. While this code is built on officially supported APIs, the library and CLI here are not officially support by Influx Data.

When installed, you have access to 2 pieces of functionality:

1. A CLI for reading and writing data to InfluxDB with IOx.
2. A client library for reading and writing data to InfluxDB with IOx.

Install

To install only the client:

python3 -m pip install pyinflux3

To install the client and CLI:

sudo python3 -m pip install "pyinflux3[cli]"

*Note: Use sudo if you would like to directly install the client onto your path. Otherwise use the --user flag.

Add a Config

To configure pyinflux3 and the CLI, do one of the following:

You can drop a config file called config.json in the directory where you are running the influx3 command:

{
    "my-config": {
        "database": "your-database",
        "host": "your-host",
        "token": "your-token",
        "org": "your-org-id",
        "active": true
    }
}

• Use the config command to create or modify a config:

  influx3 config \
  --name="my-config" \
  --database="<database or bucket name>" \
  --host="us-east-1-1.aws.cloud2.influxdata.com" \
  --token="<your token>" \
  --org="<your org ID>"
  

If you are running against InfluxDB Cloud Serverless, then use the bucket name as the database in your configuration.

Run as a Command

influx3 sql "select * from anomalies"

influx3 write testmes f=7 

Query and Write Interactively

In your terminal, enter the following command:

influx3

influx3 displays the (>) interactive prompt and waits for input.

Welcome to my IOx CLI.

(>)

To query, type sql at the prompt.

(>) sql

At the (sql >) prompt, enter your query statement:

(sql >) select * from home

The influx3 CLI displays query results in Markdown table format--for example:

|     |   co |   hum | room        |   temp | time                          |
|----:|-----:|------:|:------------|-------:|:------------------------------|
|   0 |    0 |  35.9 | Kitchen     |   21   | 2023-03-09 08:00:00           |
|   1 |    0 |  35.9 | Kitchen     |   21   | 2023-03-09 08:00:50           |

To write, type write at the (>) prompt.

(>) write

At the (write >) prompt, enter line protocol data.

(>) write 
home,room=kitchen temp=70.5,hum=80

To exit a prompt, enter exit.

Write from a File

Both the InfluxDB CLI and Client libary support writing from a CSV file. The CSV file must have a header row with the column names. The there must be a column containing a timestamp. Here are the parse options:

• --file - The path to the csv file.
• --time - The name of the column containing the timestamp.
• --measurement - The name of the measurment to store the CSV data under. (Currently only supports user specified string)
• --tags - (optional) Specify an array of column names to use as tags. (Currently only supports user specified strings) for example: --tags=host,region

influx3 write_csv --file ./Examples/example.csv --measurement table2 --time Date --tags host,region

Client library

This project also includes a new client library that strives for utter simplicity. It includes 3 functions, a constuctor, write(), and read().

Contribution

If you are working on a new feature for either the CLI or the Client Libary please make sure you test both for breaking changes. This can currently be achived using the following method:

python3 -m venv .venv
source .venv/bin/activate
chmod +x ./test/test-package.sh 
./test/test-package.sh 

Any time you make changes in your code and want to retest just run the script again:

./test/test-package.sh
