InfluxDB client

Project description

# influx-client

InfluxDB client compatible with 1.5. This client uses the awesome
[requests]( library to provide
connection pooling for each unique InfluxDB URL given.

This InfluxDB client is created, maintained, and supported by [Axiom

## Prerequisites

This client has only been tested and used against InfluxDB 1.5 and Python 3.5.
If you want to support any other environments, please submit a pull request.

## Installation

You can install this client [via PyPI](

$ pip install influx-client

Or by cloning this repository:

$ git clone
$ cd influx-client
$ pip install . # For a regular install
$ python develop # OR for a development install

## Usage

This section describes basic usage.

#### Quickstart Example

This InfluxDB client is designed to be very simple. It takes a URL to the
InfluxDB API on creation, and otherwise supplies all parameters per `write()`

If the InfluxDB API returns an error that the chosen database does not exist,
the client will issue a `CREATE DATABASE ...` query, followed by retrying the
write request.

from influx import InfluxDB

# This creates the client instance... subsequent calls with the same URL will
# return the exact same instance, allowing you to use socket pooling for faster
# requests with less resources.
client = InfluxDB('')

# Creating the database is optional - calls to write() will try to create the
# database if it does not exist.

# You can write as many fields and tags as you like, or override the *time* for
# the data points
client.write('mydatabase', 'mymeasurement', fields={'value': 1.0},
tags={'env': 'example'})

# You can query for data relative to now()
data = client.select_recent('mydatabase', 'mymeasurement', time_relative='1h')

# You can clean up after yourself, for example in testing environments

# Subsequent client creation will give the same instance
client2 = InfluxDB('')
client is client2 # This is True

### Repository Layout

There are a few important pieces in this repository:

- `influx/` - The influx Python package
- `test/` - Python nosetests
- `Dockerfile`, `docker-compose.yml` - Docker configuration for testing
- `LICENSE`, `` - Documentation and legal

### Running Tests

You can run the full test suite with supporting InfluxDB instance using

The following command will build the test image and run all tests:

docker-compose up --build --force-recreate --remove-orphans --exit-code-from influx

When tests are complete, you can clean up supporting services using:

docker-compose down

### Making Pull Requests

Pull requests must pass CI to be considered for inclusion. If your pull request
does not have squashed commits, your commits should follow the *topic:
description* style. See the commit history for examples.

## API

This section describes the public API for *influx-client*.

### `InfluxDB(`*`url`*`)`

This is the main InfluxDB client. It works as a singleton instance per *url*.
In threaded or event loop based environments it relies on the *requests*
library connection pooling (which in turn relies on *urllib3*) for thread

- **url** (*str*) - URL to InfluxDB API (such as `''`)

#### `.create_database(`*`database`*`)`

Issues a `CREATE DATABASE ...` request to the InfluxDB API. This is an
idempotent operation.

- **database** (*str*) - Database name

#### `.drop_database(`*`database`*`)`

Issues a `DROP DATABASE ...` request to the InfluxDB API. This will raise a 404
HTTPError if the database does not exist.

- **database** (*str*) - Database name

#### `.write(`*`database, measurement, fields, tags={}, time=None`*`)`

Write data points to the specified *database* and *measurement*.

- **database** (*str*) - Database name
- **measurement** (*str*) - Measurement name
- **fields** (*dict*) - Dictionary of *field_name: value* data points
- **tags** (*dict*, optional) - Dictionary of *tag_name: value* tags to
associate with the data points
- **time** (*datetime*, optional) - Datetime to use instead of InfluxDB's
server-side "now"

#### `.select_recent(`*`database, measurement, fields='*', tags={}, relative_time='15m'`*`)`

Query the InfluxDB API for *measurement* in *database*, using the *fields*
string, limited to matching *tags* for the recent *relative_time*.

Returns the raw JSON response from InfluxDB.

- **database** (*str*) - Database name
- **measurement** (*str*) - Measurement name
- **fields** (*str*, default `'*'`) - String formatted fields for `SELECT`
- **tags** (*dict*, optional) - Dictionary of *tag_name: value* tags to match
- **relative_time** (*str*, default `'15m'`) - Relative time string
