Set up InfluxDB 2.0
To set up InfluxDB 2.0, you need to create an initial user, an organization, and a bucket.
A user is an account that has access to InfluxDB 2.0. You can create multiple users with different permissions and roles.
An organization is a logical grouping of users and buckets. You can create multiple organizations for different projects or teams.
A bucket is a collection of time series data that has a retention policy. A retention policy is a duration that determines how long InfluxDB 2.0 keeps your data. You can create multiple buckets with different retention policies.
To set up InfluxDB 2.0, you can follow these steps:
Open a browser and go to to access the InfluxDB UI.
Enter your desired username, password, organization name, and bucket name.
Click Continue.
You will see a confirmation page with your authentication token. You can copy and save this token for later use.
Click Start.
You can also use the InfluxDB CLI (command-line interface) to set up InfluxDB 2.0. To do so, you need to run the following command in a terminal:
influx setup
You will be prompted to enter the same information as in the UI. After you complete the setup, you will see your authentication token in the terminal output.
Write data to InfluxDB 2.0
To write data to InfluxDB 2.0, you need to use the InfluxDB Line Protocol, which is a text-based format that specifies the measurement, tag set, field set, and timestamp of a data point.
A measurement is a name that identifies the data series.
A tag set is a collection of key-value pairs that add metadata and context to the data point.
A field set is a collection of key-value pairs that represent the actual data values.
A timestamp is a date and time that marks when the data point was recorded.
For example, the following line protocol writes a data point to InfluxDB 2.0:
temperature,sensor=A,location=room1 value=23.4 1624250242000000000
This data point has:
A measurement of temperature
A tag set of sensor=A and location=room1
A field set of value=23.4
A timestamp of 1624250242000000000 (in nanoseconds)
To write data to InfluxDB 2.0, you can use one of the following methods:
The InfluxDB UI
The InfluxDB CLI
The InfluxDB API
The Telegraf agent
The Flux language
The InfluxDB client libraries

Replace with the name of your bucket, with the name of your organization, with the time precision of your data (ns, us, ms, s, m, or h), and with your line protocol.
The InfluxDB API
To write data to InfluxDB 2.0 using the API, you can follow these steps:
Open a terminal and run the following command to write data to a bucket using curl:
curl -XPOST " \ --header "Authorization : Token " \ --data-raw ''
Replace with the name of your organization, with the name of your bucket, with the time precision of your data (ns, us, ms, s, m, or h), with your authentication token, and with your line protocol.
Query data from InfluxDB 2.0
To query data from InfluxDB 2.0, you need to use the Flux language, which is a functional and declarative language that allows you to manipulate and analyze your data.
Flux has a syntax that consists of pipes (>), functions, arguments, and operators. You can use Flux to filter, group, aggregate, transform, join, and visualize your data.
For example, the following Flux query returns the average temperature value for each sensor and location in the last hour:
from(bucket: "temperature") > range(start: -1h) > filter(fn: (r) => r._measurement == "temperature") > group(columns: ["sensor", "location"]) > mean()
To query data from InfluxDB 2.0, you can use one of the following methods:
The InfluxDB UI
The InfluxDB CLI
The InfluxDB API
The Flux REPL
The InfluxDB client libraries

curl -XPOST " \ --header "Authorization: Token " \ --header "Content-Type: application/vnd.flux" \ --data ''
Replace with the name of your organization, with your authentication token, and with your Flux query.
Process data with InfluxDB 2.0
To process data with InfluxDB 2.0, you can use the Task feature, which is a background processing and monitoring agent that runs Flux scripts at specified intervals.
You can use Tasks to perform various operations on your data, such as downsampling, anomaly detection, alerting, etc.
To create a Task, you need to specify a name, a description, an organization, a schedule (using cron syntax), and a Flux script.
For example, the following Task downsamples the temperature data every hour and writes it to another bucket:
option task = name: "Downsample temperature", description: "Downsample temperature data every hour", every: 1h, from(bucket: "temperature") > range(start: -task.every) > filter(fn: ( r) => r._measurement == "temperature") > aggregateWindow(every: 1m, fn: mean) > to(bucket: "temperature_downsampled", org: "example-org")
To create a Task using the UI, you can follow these steps:
Open a browser and go to to access the InfluxDB UI.
Click on Tasks in the left menu and then click on Create Task.
Enter your Task name, description, organization, and schedule.
Enter your Flux script in the script editor.
Click on Save Task.
To create a Task using the CLI, you can follow these steps:
