InfluxDB 2.0 python client

User Guide

Query 

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

Write 

The WriteApi supports synchronous, asynchronous and batching writes into InfluxDB 2.0. The data should be passed as a InfluxDB Line Protocol, Data Point 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 structure
Dictionary style mapping with keys: measurement, tags, fields and time or custom structure
NamedTuple
Data Classes
Pandas DataFrame
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.

Batching 

The batching is configurable by write_options:

Property	Description	Default Value
batch_size	the number of data point 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`
max_close_wait	the maximum amount of time to wait for batches to flush when .close() is called	`300_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]`	`2`

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 

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)

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 configuration file you are able to specify default tags by tags segment.

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

[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 or a JSON 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

self.client = InfluxDBClient.from_env_properties()

Synchronous client 

Data are writes in a synchronous HTTP request.

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

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

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

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

client.close()

Delete data 

The delete_api.py supports deletes points from an InfluxDB bucket.

from influxdb_client import InfluxDBClient

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

delete_api = client.delete_api()

"""
Delete Data
"""
start = "1970-01-01T00:00:00Z"
stop = "2021-02-01T00:00:00Z"
delete_api.delete(start, stop, '_measurement="my_measurement"', bucket='my-bucket', org='my-org')

"""
Close client
"""
client.close()

Pandas DataFrame 

Note

For DataFrame querying you should install Pandas dependency via pip install 'influxdb-client[extra]'.

Note

Note that if a query returns more then one table then the client generates a DataFrame for each of them.

The client is able to retrieve data in Pandas DataFrame format thought query_data_frame:

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

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

                                        '|> keep(columns: ["location", "temperature"])')
print(data_frame.to_string())

"""
Close client
"""
client.close()

Output:

    result table  location  temperature
0  _result     0  New York         24.3
1  _result     1    Prague         25.3

How to use Asyncio 

Starting from version 1.27.0 for Python 3.7+ the influxdb-client package supports async/await based on asyncio, aiohttp and aiocsv. You can install aiohttp and aiocsv directly:

$ python -m pip install influxdb-client aiohttp aiocsv

or use the [async] extra:

$ 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?.

Async APIs 

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

influxdb_client.client.write_api_async.WriteApiAsync
influxdb_client.client.query_api_async.QueryApiAsync
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:

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 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 structure
Dictionary style mapping with keys: measurement, tags, fields and time or custom structure

        _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 influxdb_client.client.query_api_async.QueryApiAsync supports retrieve data as:

List of influxdb_client.client.flux_table.FluxTable
Stream of influxdb_client.client.flux_table.FluxRecord via typing.AsyncGenerator
Pandas DataFrame
Stream of Pandas DataFrame via typing.AsyncGenerator
Raw str output

    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.

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.

Gzip support 

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:

from influxdb_client import InfluxDBClient

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

Proxy configuration 

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.

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:

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

Authentication 

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.

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.

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) (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.

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.

Nanosecond precision 

The Python’s datetime 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 that is replacement for python datetime.datetime object and also you should set a proper DateTimeHelper to the client.

Handling Errors 

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:

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.

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.

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)

Logging 

The client uses Python’s logging 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:

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:

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

Note

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

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,

Int Types:

The following example shows how to configure the types of integers fields. It is useful when you want to serialize integers always as float to avoid field type conflict or use unsigned 64-bit integer as the type for serialization.

# Use custom dictionary structure
dict_structure = {
    "measurement": "h2o_feet",
    "tags": {"location": "coyote_creek"},
    "fields": {
        "water_level": 1.0,
        "some_counter": 108913123234
    },
    "time": 1
}

point = Point.from_dict(dict_structure, field_types={"some_counter": "uint"})

Parameters:

dictionary – dictionary for serialize into data Point
write_precision – sets the precision for the supplied time values

Key record_measurement_key:

key of dictionary with specified measurement

Key record_measurement_name:

static measurement name for data Point

Key record_time_key:

key of dictionary with specified timestamp

Key record_tag_keys:

list of dictionary keys to use as a tag

Key record_field_keys:

list of dictionary keys to use as a field

Key field_types:

optional dictionary to specify types of serialized fields. Currently, is supported customization for integer types. Possible integers types:

int - serialize integers as “Signed 64-bit integers” - 9223372036854775807i (default behaviour)

uint - serialize integers as “Unsigned 64-bit integers” - 9223372036854775807u

float - serialize integers as “IEEE-754 64-bit floating-point numbers”. Useful for unify number types in your pipeline to avoid field type conflict - 9223372036854775807

The field_types can be also specified as part of incoming dictionary. For more info see an example above.

from influxdb import SeriesHelper

my_client = InfluxDBClient(host='127.0.0.1', port=8086, username='root', password='root', database='dbname')


class MySeriesHelper(SeriesHelper):
    class Meta:
        client = my_client
        series_name = 'events.stats.{server_name}'
        fields = ['some_stat', 'other_stat']
        tags = ['server_name']

MySeriesHelper(server_name='us.east-1', some_stat=159, other_stat=10)
MySeriesHelper(server_name='us.east-1', some_stat=158, other_stat=20)

MySeriesHelper.commit()

The influxdb-client-python doesn’t have an equivalent implementation for MySeriesHelper, but there is an option to use Python Data Classes way:

influxdb-client-python

from dataclasses import dataclass

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


@dataclass
class Car:
    """
    DataClass structure - Car
    """
    engine: str
    type: str
    speed: float


with InfluxDBClient(url='http://localhost:8086', token='my-token', org='my-org') as client:
    write_api = client.write_api(write_options=SYNCHRONOUS)

    car = Car('12V-BT', 'sport-cars', 125.25)

    write_api.write(bucket="my-bucket",
                    record=car,
                    record_measurement_name="performance",
                    record_tag_keys=["engine", "type"],
                    record_field_keys=["speed"])

Writing Pandas DataFrame

influxdb-python

import pandas as pd

from influxdb import InfluxDBClient

df = pd.DataFrame(data=list(range(30)),
                  index=pd.date_range(start='2014-11-16', periods=30, freq='H'),
                  columns=['0'])

client = InfluxDBClient(host='127.0.0.1', port=8086, username='root', password='root', database='dbname')

client.write_points(df, 'demo', protocol='line')

influxdb-client-python

import pandas as pd

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

with InfluxDBClient(url='http://localhost:8086', token='my-token', org='my-org') as client:
    write_api = client.write_api(write_options=SYNCHRONOUS)

    df = pd.DataFrame(data=list(range(30)),
                      index=pd.date_range(start='2014-11-16', periods=30, freq='H'),
                      columns=['0'])

    write_api.write(bucket='my-bucket', record=df, data_frame_measurement_name='demo')

Querying

influxdb-python

from influxdb import InfluxDBClient

client = InfluxDBClient(host='127.0.0.1', port=8086, username='root', password='root', database='dbname')

points = client.query('SELECT * from cpu').get_points()
for point in points:
    print(point)

influxdb-client-python

from influxdb_client import InfluxDBClient

with InfluxDBClient(url='http://localhost:8086', token='my-token', org='my-org', debug=True) as client:
    query = '''from(bucket: "my-bucket")
  |> range(start: -10000d)
  |> filter(fn: (r) => r["_measurement"] == "cpu")
  |> pivot(rowKey:["_time"], columnKey: ["_field"], valueColumn: "_value")
'''

    tables = client.query_api().query(query)
    for record in [record for table in tables for record in table.records]:
        print(record.values)

If you would like to omit boilerplate columns such as _result, _table, _start, … you can filter the record values by following expression:

print({k: v for k, v in record.values.items() if k not in ['result', 'table', '_start', '_stop', '_measurement']})

For more info see Flux Response Format.

Development

The following document covers how to develop the InfluxDB client library locally. Including how to run tests and build the docs.

tl;dr 

# from your forked repo, create and activate a virtualenv
python -m virtualenv venv
. venv/bin/activate
# install the library as editable with all dependencies
make install
# make edits
# run lint and tests
make lint test

Getting Started 

Install Python

Most distributions include Python by default, so before going too far, try running python --version to see if it already exists. You may also have to specify python3 --version, for example, on Ubuntu.
Fork and clone the repo

The rest of this assumes you have cloned your fork of the upstream client library and are in the same directory of the forked repo.
Set up a virtual environment.
Python virtual environments let you install specific versioned dependencies in a contained manner. This way, you do not pollute or have conflicts on your system with different versions.
python -m virtualenv venv . venv/bin/activate
Having a shell prompt change via starship or something similar is nice as it will let you know when and which virtual environment in you are in.

To exit the virtual environment, run deactivate.
Install the client library
To install the local version of the client library run:
make install
This will install the library as editable with all dependencies. This includes all dependencies that are used for all possible features as well as testing requirements.
Make changes and test
At this point, a user can make the required changes necessary and run any tests or scripts they have.

Before putting up a PR, the user should attempt to run the lint and tests locally. Lint will ensure the formatting of the code, while tests will run integration tests against an InfluxDB instance. For details on that set up see the next section.
make lint test

Linting 

The library uses flake8 to do linting and can be run with:

make lint

Testing 

The built-in tests assume that there is a running instance of InfluxDB 2.x up and running. This can be accomplished by running the scripts/influxdb-restart.sh script. It will launch an InfluxDB 2.x instance with Docker and make it available locally on port 8086.

Once InfluxDB is available, run all the tests with:

make test

Code Coverage 

After running the tests, an HTML report of the tests is available in the htmlcov directory. Users can open html/index.html file in a browser and see a full report for code coverage across the whole project. Clicking on a specific file will show a line-by-line report of what lines were or were not covered.

Documentation 

The docs are built using Sphinx. To build all the docs run:

make docs

This will build and produce a sample version of the web docs at docs/_build/html/index.html. From there the user can view the entire site and ensure changes are rendered correctly.

This repository contains the Python client library for use with InfluxDB 2.x and Flux. InfluxDB 3.x users should instead use the lightweight v3 client library. InfluxDB 1.x users should use the v1 client library.

For ease of migration and a consistent query and write experience, v2 users should consider using InfluxQL and the v1 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

InfluxDB python library uses 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 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, you can install latest version directly:

pip install 'influxdb-client[ciso]'

Then import the package:

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 see How to use Asyncio.

Setuptools

Install via Setuptools.

python setup.py install --user

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

Getting Started

Please follow the Installation and then run the following:

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

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
cert_file - path to the certificate that will be used for mTLS authentication
cert_key_file - path to the file contains private key for mTLS certificate
cert_key_password - string or function which returns password for decrypting the mTLS private key
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

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

[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_CERT_FILE - path to the certificate that will be used for mTLS authentication
INFLUXDB_V2_CERT_KEY_FILE - path to the file contains private key for mTLS certificate
INFLUXDB_V2_CERT_KEY_PASSWORD - string or function which returns password for decrypting the mTLS private key
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

self.client = InfluxDBClient.from_env_properties()

Profile query

The Flux Profiler package 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:

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:

===============
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)

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:

 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:

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}
