This repository contains the Python client library for the InfluxDB 2.0.

Note: Use this client library with InfluxDB 2.x and InfluxDB 1.8+. For connecting to InfluxDB 1.7 or earlier instances, use the influxdb-python <https://github.com/influxdata/influxdb-python>_ client library. The API of the influxdb-client-python is not the backwards-compatible with the old one - influxdb-python.

Documentation

This section contains links to the client library documentation.

Installation

.. marker-install-start

InfluxDB python library uses RxPY <https://github.com/ReactiveX/RxPY>__ - The Reactive Extensions for Python (RxPY).

Python 3.7 or later is required.

.. note::

It is recommended to use ``ciso8601`` with client for parsing dates. ``ciso8601`` is much faster than built-in Python datetime. Since it's written as a ``C`` module the best way is build it from sources:

**Windows**:

You have to install `Visual C++ Build Tools 2015 <http://go.microsoft.com/fwlink/?LinkId=691126&fixForIE=.exe>`_ to build ``ciso8601`` by ``pip``.

**conda**:

Install from sources: ``conda install -c conda-forge/label/cf202003 ciso8601``.

pip install ^^^^^^^^^^^

The python package is hosted on PyPI <https://pypi.org/project/influxdb-client/>_, you can install latest version directly:

.. code-block:: sh

pip install 'influxdb-client[ciso]'

Then import the package:

.. code-block:: python

import influxdb_client

If your application uses async/await in Python you can install with the async extra::

$ pip install influxdb-client[async]

For more info se How to use Asyncio_.

Setuptools ^^^^^^^^^^

Install via Setuptools <http://pypi.python.org/pypi/setuptools>_.

.. code-block:: sh

python setup.py install --user

(or sudo python setup.py install to install the package for all users)

.. marker-install-end

Getting Started

Please follow the Installation_ and then run the following:

.. marker-query-start

.. code-block:: python

from influxdb_client import InfluxDBClient, Point from influxdb_client.client.write_api import SYNCHRONOUS

bucket = "my-bucket"

client = InfluxDBClient(url="http://localhost:8086", token="my-token", org="my-org")

write_api = client.write_api(write_options=SYNCHRONOUS) query_api = client.query_api()

p = Point("my_measurement").tag("location", "Prague").field("temperature", 25.3)

write_api.write(bucket=bucket, record=p)

using Table structure

tables = query_api.query('from(bucket:"my-bucket") |> range(start: -10m)')

for table in tables: print(table) for row in table.records: print (row.values)

using csv library

csv_result = query_api.query_csv('from(bucket:"my-bucket") |> range(start: -10m)') val_count = 0 for row in csv_result: for cell in row: val_count += 1

.. marker-query-end

Client configuration

Via File ^^^^^^^^ A client can be configured via *.ini file in segment influx2.

The following options are supported:

url - the url to connect to InfluxDB
org - default destination organization for writes and queries
token - the token to use for the authorization
timeout - socket timeout in ms (default value is 10000)
verify_ssl - set this to false to skip verifying SSL certificate when calling API from https server
ssl_ca_cert - set this to customize the certificate file to verify the peer
connection_pool_maxsize - set the number of connections to save that can be reused by urllib3
auth_basic - enable http basic authentication when talking to a InfluxDB 1.8.x without authentication but is accessed via reverse proxy with basic authentication (defaults to false)
profilers - set the list of enabled Flux profilers <https://docs.influxdata.com/influxdb/v2.0/reference/flux/stdlib/profiler/>_

.. code-block:: python

self.client = InfluxDBClient.from_config_file("config.ini")

.. code-block::

[influx2]
url=http://localhost:8086
org=my-org
token=my-token
timeout=6000
verify_ssl=False

Via Environment Properties ^^^^^^^^^^^^^^^^^^^^^^^^^^ A client can be configured via environment properties.

Supported properties are:

INFLUXDB_V2_URL - the url to connect to InfluxDB
INFLUXDB_V2_ORG - default destination organization for writes and queries
INFLUXDB_V2_TOKEN - the token to use for the authorization
INFLUXDB_V2_TIMEOUT - socket timeout in ms (default value is 10000)
INFLUXDB_V2_VERIFY_SSL - set this to false to skip verifying SSL certificate when calling API from https server
INFLUXDB_V2_SSL_CA_CERT - set this to customize the certificate file to verify the peer
INFLUXDB_V2_CONNECTION_POOL_MAXSIZE - set the number of connections to save that can be reused by urllib3
INFLUXDB_V2_AUTH_BASIC - enable http basic authentication when talking to a InfluxDB 1.8.x without authentication but is accessed via reverse proxy with basic authentication (defaults to false)
INFLUXDB_V2_PROFILERS - set the list of enabled Flux profilers <https://docs.influxdata.com/influxdb/v2.0/reference/flux/stdlib/profiler/>_

.. code-block:: python

self.client = InfluxDBClient.from_env_properties()

Profile query ^^^^^^^^^^^^^

The Flux Profiler package <https://docs.influxdata.com/influxdb/v2.0/reference/flux/stdlib/profiler/>_ provides performance profiling tools for Flux queries and operations.

You can enable printing profiler information of the Flux query in client library by:

set QueryOptions.profilers in QueryApi,
set INFLUXDB_V2_PROFILERS environment variable,
set profilers option in configuration file.

When the profiler is enabled, the result of flux query contains additional tables "profiler/*". In order to have consistent behaviour with enabled/disabled profiler, FluxCSVParser excludes "profiler/*" measurements from result.

Example how to enable profilers using API:

.. code-block:: python

q = '''
    from(bucket: stringParam)
      |> range(start: -5m, stop: now())
      |> filter(fn: (r) => r._measurement == "mem")
      |> filter(fn: (r) => r._field == "available" or r._field == "free" or r._field == "used")
      |> aggregateWindow(every: 1m, fn: mean)
      |> pivot(rowKey:["_time"], columnKey: ["_field"], valueColumn: "_value")
'''
p = {
    "stringParam": "my-bucket",
}

query_api = client.query_api(query_options=QueryOptions(profilers=["query", "operator"]))
csv_result = query_api.query(query=q, params=p)

Example of a profiler output:

.. code-block::

===============
Profiler: query
===============

from(bucket: stringParam)
  |> range(start: -5m, stop: now())
  |> filter(fn: (r) => r._measurement == "mem")
  |> filter(fn: (r) => r._field == "available" or r._field == "free" or r._field == "used")
  |> aggregateWindow(every: 1m, fn: mean)
  |> pivot(rowKey:["_time"], columnKey: ["_field"], valueColumn: "_value")

You can also use callback function to get profilers output. Return value of this callback is type of FluxRecord.

Example how to use profilers with callback:

.. code-block:: python

 class ProfilersCallback(object):
    def __init__(self):
        self.records = []

    def __call__(self, flux_record):
        self.records.append(flux_record.values)

callback = ProfilersCallback()

query_api = client.query_api(query_options=QueryOptions(profilers=["query", "operator"], profiler_callback=callback))
tables = query_api.query('from(bucket:"my-bucket") |> range(start: -10m)')

for profiler in callback.records:
    print(f'Custom processing of profiler result: {profiler}')

Example output of this callback:

.. code-block::

Custom processing of profiler result: {'result': '_profiler', 'table': 0, '_measurement': 'profiler/query', 'TotalDuration': 18843792, 'CompileDuration': 1078666, 'QueueDuration': 93375, 'PlanDuration': 0, 'RequeueDuration': 0, 'ExecuteDuration': 17371000, 'Concurrency': 0, 'MaxAllocated': 448, 'TotalAllocated': 0, 'RuntimeErrors': None, 'flux/query-plan': 'digraph {\r\n  ReadRange2\r\n  generated_yield\r\n\r\n  ReadRange2 -> generated_yield\r\n}\r\n\r\n', 'influxdb/scanned-bytes': 0, 'influxdb/scanned-values': 0}

How to use

Writes ^^^^^^ .. marker-writes-start

The WriteApi <https://github.com/influxdata/influxdb-client-python/blob/master/influxdb_client/client/write_api.py>_ supports synchronous, asynchronous and batching writes into InfluxDB 2.0. The data should be passed as a InfluxDB Line Protocol <https://docs.influxdata.com/influxdb/latest/write_protocols/line_protocol_tutorial/>\ , Data Point <https://github.com/influxdata/influxdb-client-python/blob/master/influxdb_client/client/write/point.py> or Observable stream.

.. warning::

The ``WriteApi`` in batching mode (default mode) is suppose to run as a singleton.
To flush all your data you should wrap the execution using ``with client.write_api(...) as write_api:`` statement
or call ``write_api.close()`` at the end of your script.

The default instance of WriteApi use batching.

The data could be written as """"""""""""""""""""""""""""

string or bytes that is formatted as a InfluxDB's line protocol
Data Point <https://github.com/influxdata/influxdb-client-python/blob/master/influxdb_client/client/write/point.py#L16>__ structure
Dictionary style mapping with keys: measurement, tags, fields and time or custom structure
NamedTuple <https://docs.python.org/3/library/collections.html#collections.namedtuple>_
Data Classes <https://docs.python.org/3/library/dataclasses.html>_
Pandas DataFrame <https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html>_
List of above items
A batching type of write also supports an Observable that produce one of an above item

You can find write examples at GitHub: influxdb-client-python/examples <https://github.com/influxdata/influxdb-client-python/tree/master/examples#writes>__.

Batching """"""""

The batching is configurable by write_options\ :

.. list-table:: :header-rows: 1

- Property
- Description
- Default Value
- batch_size
- the number of data pointx to collect in a batch
- 1000
- flush_interval
- the number of milliseconds before the batch is written
- 1000
- jitter_interval
- the number of milliseconds to increase the batch flush interval by a random amount
- 0
- retry_interval
- the number of milliseconds to retry first unsuccessful write. The next retry delay is computed using exponential random backoff. The retry interval is used when the InfluxDB server does not specify "Retry-After" header.
- 5000
- max_retry_time
- maximum total retry timeout in milliseconds.
- 180_000
- max_retries
- the number of max retries when write fails
- 5
- max_retry_delay
- the maximum delay between each retry attempt in milliseconds
- 125_000
- exponential_base
- the base for the exponential retry delay, the next delay is computed using random exponential backoff as a random value within the interval retry_interval * exponential_base^(attempts-1) and retry_interval * exponential_base^(attempts). Example for retry_interval=5_000, exponential_base=2, max_retry_delay=125_000, total=5 Retry delays are random distributed values within the ranges of [5_000-10_000, 10_000-20_000, 20_000-40_000, 40_000-80_000, 80_000-125_000]

Default Tags """"""""""""

Sometimes is useful to store same information in every measurement e.g. hostname, location, customer. The client is able to use static value or env property as a tag value.

The expressions:

California Miner - static value
${env.hostname} - environment property

Via API

.. code-block:: python

point_settings = PointSettings()
point_settings.add_default_tag("id", "132-987-655")
point_settings.add_default_tag("customer", "California Miner")
point_settings.add_default_tag("data_center", "${env.data_center}")

self.write_client = self.client.write_api(write_options=SYNCHRONOUS, point_settings=point_settings)

.. code-block:: python

self.write_client = self.client.write_api(write_options=SYNCHRONOUS,
                                              point_settings=PointSettings(**{"id": "132-987-655",
                                                                              "customer": "California Miner"}))

Via Configuration file

In a init <https://docs.python.org/3/library/configparser.html>_ configuration file you are able to specify default tags by tags segment.

.. code-block:: python

self.client = InfluxDBClient.from_config_file("config.ini")

.. code-block::

[influx2]
url=http://localhost:8086
org=my-org
token=my-token
timeout=6000

[tags]
id = 132-987-655
customer = California Miner
data_center = ${env.data_center}

You can also use a TOML <https://toml.io/en/>_ or aJSON <https://www.json.org/json-en.html>_ format for the configuration file.

Via Environment Properties

You are able to specify default tags by environment properties with prefix INFLUXDB_V2_TAG_.

Examples:

INFLUXDB_V2_TAG_ID
INFLUXDB_V2_TAG_HOSTNAME

.. code-block:: python

self.client = InfluxDBClient.from_env_properties()

Synchronous client """"""""""""""""""

Data are writes in a synchronous HTTP request.

.. code-block:: python

Flux data structure: FluxTable <https://github.com/influxdata/influxdb-client-python/blob/master/influxdb_client/client/flux_table.py#L5>, FluxColumn <https://github.com/influxdata/influxdb-client-python/blob/master/influxdb_client/client/flux_table.py#L22> and FluxRecord <https://github.com/influxdata/influxdb-client-python/blob/master/influxdb_client/client/flux_table.py#L31>_

Advanced Usage

Gzip support ^^^^^^^^^^^^ .. marker-gzip-start

InfluxDBClient does not enable gzip compression for http requests by default. If you want to enable gzip to reduce transfer data's size, you can call:

.. code-block:: python

from influxdb_client import InfluxDBClient

_db_client = InfluxDBClient(url="http://localhost:8086", token="my-token", org="my-org", enable_gzip=True)

.. marker-gzip-end

Authenticate to the InfluxDB ^^^^^^^^^^^^^^^^^^^^^^^^^^^^ .. marker-authenticate-start

InfluxDBClient supports three options how to authorize a connection:

Token
Username & Password
HTTP Basic

Token """""

Use the token to authenticate to the InfluxDB API. In your API requests, an Authorization header will be send. The header value, provide the word Token followed by a space and an InfluxDB API token. The word `token`` is case-sensitive.

.. code-block:: python

from influxdb_client import InfluxDBClient

with InfluxDBClient(url="http://localhost:8086", token="my-token") as client

.. note:: Note that this is a preferred way how to authenticate to InfluxDB API.

Username & Password """""""""""""""""""

Authenticates via username and password credentials. If successful, creates a new session for the user.

.. code-block:: python

from influxdb_client import InfluxDBClient

with InfluxDBClient(url="http://localhost:8086", username="my-user", password="my-password") as client

.. warning::

The ``username/password`` auth is based on the HTTP "Basic" authentication.
The authorization expires when the `time-to-live (TTL) <https://docs.influxdata.com/influxdb/latest/reference/config-options/#session-length>`__
(default 60 minutes) is reached and client produces ``unauthorized exception``.

HTTP Basic """"""""""

Use this to enable basic authentication when talking to a InfluxDB 1.8.x that does not use auth-enabled but is protected by a reverse proxy with basic authentication.

.. code-block:: python

from influxdb_client import InfluxDBClient

with InfluxDBClient(url="http://localhost:8086", auth_basic=True, token="my-proxy-secret") as client

.. warning:: Don't use this when directly talking to InfluxDB 2.

.. marker-authenticate-end

Proxy configuration ^^^^^^^^^^^^^^^^^^^ .. marker-proxy-start

You can configure the client to tunnel requests through an HTTP proxy. The following proxy options are supported:

proxy - Set this to configure the http proxy to be used, ex. http://localhost:3128
proxy_headers - A dictionary containing headers that will be sent to the proxy. Could be used for proxy authentication.

.. code-block:: python

from influxdb_client import InfluxDBClient

with InfluxDBClient(url="http://localhost:8086", token="my-token", org="my-org", proxy="http://localhost:3128") as client:

.. note::

If your proxy notify the client with permanent redirect (``HTTP 301``) to **different host**.
The client removes ``Authorization`` header, because otherwise the contents of ``Authorization`` is sent to third parties
which is a security vulnerability.

You can change this behaviour by:

.. code-block:: python

   from urllib3 import Retry
   Retry.DEFAULT_REMOVE_HEADERS_ON_REDIRECT = frozenset()
   Retry.DEFAULT.remove_headers_on_redirect = Retry.DEFAULT_REMOVE_HEADERS_ON_REDIRECT

.. marker-proxy-end

Delete data ^^^^^^^^^^^ .. marker-delete-start

The delete_api.py <influxdb_client/client/delete_api.py>_ supports deletes points <https://v2.docs.influxdata.com/v2.0/reference/glossary/#point>_ from an InfluxDB bucket.

.. code-block:: python

from influxdb_client import InfluxDBClient

client = InfluxDBClient(url="http://localhost:8086", token="my-token")

delete_api = client.delete_api()

"""

"""

.. marker-delete-end

InfluxDB 1.8 API compatibility ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

InfluxDB 1.8.0 introduced forward compatibility APIs <https://docs.influxdata.com/influxdb/v1.8/tools/api/#influxdb-2-0-api-compatibility-endpoints>_ for InfluxDB 2.0. This allow you to easily move from InfluxDB 1.x to InfluxDB 2.0 Cloud or open source.

The following forward compatible APIs are available:

======================================================= ==================================================================================================== ======= API Endpoint Description ======================================================= ==================================================================================================== ======= query_api.py <influxdb_client/client/query_api.py>_ /api/v2/query <https://docs.influxdata.com/influxdb/v1.8/tools/api/#apiv2query-http-endpoint>_ Query data in InfluxDB 1.8.0+ using the InfluxDB 2.0 API and Flux <https://docs.influxdata.com/flux/latest/>_ (endpoint should be enabled by flux-enabled option <https://docs.influxdata.com/influxdb/v1.8/administration/config/#flux-enabled-false>) write_api.py <influxdb_client/client/write_api.py> /api/v2/write <https://docs.influxdata.com/influxdb/v1.8/tools/api/#apiv2write-http-endpoint>_ Write data to InfluxDB 1.8.0+ using the InfluxDB 2.0 API ping() <influxdb_client/client/influxdb_client.py>_ /ping <https://docs.influxdata.com/influxdb/v1.8/tools/api/#ping-http-endpoint>_ Check the status of your InfluxDB instance ======================================================= ==================================================================================================== =======

For detail info see InfluxDB 1.8 example <examples/influxdb_18_example.py>_.

Handling Errors ^^^^^^^^^^^^^^^ .. marker-handling-errors-start

Errors happen and it's important that your code is prepared for them. All client related exceptions are delivered from InfluxDBError. If the exception cannot be recovered in the client it is returned to the application. These exceptions are left for the developer to handle.

Almost all APIs directly return unrecoverable exceptions to be handled this way:

.. code-block:: python

from influxdb_client import InfluxDBClient
from influxdb_client.client.exceptions import InfluxDBError
from influxdb_client.client.write_api import SYNCHRONOUS

with InfluxDBClient(url="http://localhost:8086", token="my-token", org="my-org") as client:
    try:
        client.write_api(write_options=SYNCHRONOUS).write("my-bucket", record="mem,tag=a value=86")
    except InfluxDBError as e:
        if e.response.status == 401:
            raise Exception(f"Insufficient write permissions to 'my-bucket'.") from e
        raise

The only exception is batching WriteAPI (for more info see Batching_). where you need to register custom callbacks to handle batch events. This is because this API runs in the background in a separate thread and isn't possible to directly return underlying exceptions.

.. code-block:: python

from influxdb_client import InfluxDBClient
from influxdb_client.client.exceptions import InfluxDBError


class BatchingCallback(object):

    def success(self, conf: (str, str, str), data: str):
        print(f"Written batch: {conf}, data: {data}")

    def error(self, conf: (str, str, str), data: str, exception: InfluxDBError):
        print(f"Cannot write batch: {conf}, data: {data} due: {exception}")

    def retry(self, conf: (str, str, str), data: str, exception: InfluxDBError):
        print(f"Retryable error occurs for batch: {conf}, data: {data} retry: {exception}")


with InfluxDBClient(url="http://localhost:8086", token="my-token", org="my-org") as client:
    callback = BatchingCallback()
    with client.write_api(success_callback=callback.success,
                          error_callback=callback.error,
                          retry_callback=callback.retry) as write_api:
        pass

HTTP Retry Strategy """"""""""""""""""" By default the client uses a retry strategy only for batching writes (for more info see Batching_). For other HTTP requests there is no one retry strategy, but it could be configured by retries parameter of InfluxDBClient.

For more info about how configure HTTP retry see details in urllib3 documentation <https://urllib3.readthedocs.io/en/latest/reference/index.html?highlight=retry#urllib3.Retry>_.

.. code-block:: python

from urllib3 import Retry

from influxdb_client import InfluxDBClient

retries = Retry(connect=5, read=2, redirect=5)
client = InfluxDBClient(url="http://localhost:8086", token="my-token", org="my-org", retries=retries)

.. marker-handling-errors-end

Nanosecond precision ^^^^^^^^^^^^^^^^^^^^ .. marker-nanosecond-start

The Python's datetime <https://docs.python.org/3/library/datetime.html>_ doesn't support precision with nanoseconds so the library during writes and queries ignores everything after microseconds.

If you would like to use datetime with nanosecond precision you should use pandas.Timestamp <https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.Timestamp.html#pandas.Timestamp>_ that is replacement for python datetime.datetime object and also you should set a proper DateTimeHelper to the client.

How to use Asyncio ^^^^^^^^^^^^^^^^^^ .. marker-asyncio-start

Starting from version 1.27.0 for Python 3.7+ the influxdb-client package supports async/await based on asyncio <https://docs.python.org/3/library/asyncio.html>_ and aiohttp <https://docs.aiohttp.org>_. You can install aiohttp directly:

.. code-block:: bash

$ python -m pip install influxdb-client aiohttp

or use the [async] extra:

.. code-block:: bash

$ python -m pip install influxdb-client[async]

.. warning::

The ``InfluxDBClientAsync`` should be initialised inside ``async coroutine``
otherwise there can be unexpected behaviour.
For more info see: `Why is creating a ClientSession outside of an event loop dangerous? <https://docs.aiohttp.org/en/stable/faq.html#why-is-creating-a-clientsession-outside-of-an-event-loop-dangerous>`__.

Async APIs """""""""" All async APIs are available via :class:~influxdb_client.client.influxdb_client_async.InfluxDBClientAsync. The async version of the client supports following asynchronous APIs:

:class:~influxdb_client.client.write_api_async.WriteApiAsync
:class:~influxdb_client.client.query_api_async.QueryApiAsync
:class:~influxdb_client.client.delete_api_async.DeleteApiAsync
Management services into influxdb_client.service supports async operation

and also check to readiness of the InfluxDB via /ping endpoint:

.. code-block:: python

    import asyncio

    from influxdb_client.client.influxdb_client_async import InfluxDBClientAsync


    async def main():
        async with InfluxDBClientAsync(url="http://localhost:8086", token="my-token", org="my-org") as client:
            ready = await client.ping()
            print(f"InfluxDB: {ready}")


    if __name__ == "__main__":
        asyncio.run(main())

Async Write API """""""""""""""

The :class:~influxdb_client.client.write_api_async.WriteApiAsync supports ingesting data as:

string or bytes that is formatted as a InfluxDB's line protocol
Data Point <https://github.com/influxdata/influxdb-client-python/blob/master/influxdb_client/client/write/point.py#L16>__ structure
Dictionary style mapping with keys: measurement, tags, fields and time or custom structure
NamedTuple <https://docs.python.org/3/library/collections.html#collections.namedtuple>_

        write_api = client.write_api()

        _point1 = Point("async_m").tag("location", "Prague").field("temperature", 25.3)
        _point2 = Point("async_m").tag("location", "New York").field("temperature", 24.3)

        successfully = await write_api.write(bucket="my-bucket", record=[_point1, _point2])

        print(f" > successfully: {successfully}")


if __name__ == "__main__":
    asyncio.run(main())

Async Query API """""""""""""""

The :class:~influxdb_client.client.query_api_async.QueryApiAsync supports retrieve data as:

List of :class:~influxdb_client.client.flux_table.FluxTable
Stream of :class:~influxdb_client.client.flux_table.FluxRecord via :class:~typing.AsyncGenerator
Pandas DataFrame <https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html>_
Stream of Pandas DataFrame <https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.html>_ via :class:~typing.AsyncGenerator
Raw :class:~str output

.. code-block:: python

import asyncio

from influxdb_client.client.influxdb_client_async import InfluxDBClientAsync


async def main():
    async with InfluxDBClientAsync(url="http://localhost:8086", token="my-token", org="my-org") as client:
        # Stream of FluxRecords
        query_api = client.query_api()
        records = await query_api.query_stream('from(bucket:"my-bucket") '
                                               '|> range(start: -10m) '
                                               '|> filter(fn: (r) => r["_measurement"] == "async_m")')
        async for record in records:
            print(record)

    asyncio.run(main())

Async Delete API """"""""""""""""

.. code-block:: python

import asyncio
from datetime import datetime

from influxdb_client.client.influxdb_client_async import InfluxDBClientAsync


async def main():
    async with InfluxDBClientAsync(url="http://localhost:8086", token="my-token", org="my-org") as client:
        start = datetime.utcfromtimestamp(0)
        stop = datetime.now()
        # Delete data with location = 'Prague'
        successfully = await client.delete_api().delete(start=start, stop=stop, bucket="my-bucket",
                                                        predicate="location = \"Prague\"")
        print(f" > successfully: {successfully}")

Management API """"""""""""""

.. code-block:: python

import asyncio

from influxdb_client import OrganizationsService
from influxdb_client.client.influxdb_client_async import InfluxDBClientAsync


async def main():
    async with InfluxDBClientAsync(url='http://localhost:8086', token='my-token', org='my-org') as client:
        # Initialize async OrganizationsService
        organizations_service = OrganizationsService(api_client=client.api_client)

        # Find organization with name 'my-org'
        organizations = await organizations_service.get_orgs(org='my-org')
        for organization in organizations.orgs:
            print(f'name: {organization.name}, id: {organization.id}')


if __name__ == "__main__":
    asyncio.run(main())

Proxy and redirects """""""""""""""""""

You can configure the client to tunnel requests through an HTTP proxy. The following proxy options are supported:

proxy - Set this to configure the http proxy to be used, ex. http://localhost:3128
proxy_headers - A dictionary containing headers that will be sent to the proxy. Could be used for proxy authentication.

.. code-block:: python

from influxdb_client.client.influxdb_client_async import InfluxDBClientAsync

async with InfluxDBClientAsync(url="http://localhost:8086", token="my-token", org="my-org", proxy="http://localhost:3128") as client:

.. note::

If your proxy notify the client with permanent redirect (``HTTP 301``) to **different host**.
The client removes ``Authorization`` header, because otherwise the contents of ``Authorization`` is sent to third parties
which is a security vulnerability.

Client automatically follows HTTP redirects. The default redirect policy is to follow up to 10 consecutive requests. The redirects can be configured via:

allow_redirects - If set to False, do not follow HTTP redirects. True by default.
max_redirects - Maximum number of HTTP redirects to follow. 10 by default.

.. marker-asyncio-end

Logging ^^^^^^^ .. marker-logging-start

The client uses uses Python's logging <https://docs.python.org/3/library/logging.html>__ facility for logging the library activity. The following logger categories are exposed:

influxdb_client.client.influxdb_client
influxdb_client.client.influxdb_client_async
influxdb_client.client.write_api
influxdb_client.client.write_api_async
influxdb_client.client.write.retry
influxdb_client.client.write.dataframe_serializer
influxdb_client.client.util.multiprocessing_helper
influxdb_client.client.http
influxdb_client.client.exceptions

The default logging level is warning without configured logger output. You can use the standard logger interface to change the log level and handler:

.. code-block:: python

import logging
import sys

from influxdb_client import InfluxDBClient

with InfluxDBClient(url="http://localhost:8086", token="my-token", org="my-org") as client:
    for _, logger in client.conf.loggers.items():
        logger.setLevel(logging.DEBUG)
        logger.addHandler(logging.StreamHandler(sys.stdout))

Debugging """""""""

For debug purpose you can enable verbose logging of HTTP requests and set the debug level to all client's logger categories by:

.. code-block:: python

client = InfluxDBClient(url="http://localhost:8086", token="my-token", debug=True)

.. note::

Both HTTP request headers and body will be logged to standard output.

.. marker-logging-end
