Query InfluxDB

To query data from InfluxDB using Flux, use from() and range. Provide the following parameters to each function:

  • from():
    • bucket or bucketID: InfluxDB bucket name or bucket ID to query.
  • range():
    • start: Earliest time to return results from.

InfluxDB requires queries to be time-bound, so from() must always be followed by range().

from(bucket: "example-bucket")
    |> range(start: -1h)

Query InfluxDB Cloud or 2.x remotely

To query InfluxDB Cloud or 2.x remotely, provide the following parameters in addition to bucket or bucketID.

from(
    bucket: "example-bucket",
    host: "http://localhost:8086",
    org: "example-org",
    token: "mYSup3r5Ecr3T70keN",
)

Query InfluxDB 1.x

To query InfluxDB 1.x, use the database-name/retention-policy-name naming convention for your bucket name. For example, to query data from the autogen retention policy in the telegraf database:

from(bucket: "telegraf/autogen")
    |> range(start: -30m)

To query the default retention policy in a database, use the same bucket naming convention, but do not provide a retention policy:

from(bucket: "telegraf/")
    |> range(start: -30m)

Results structure

from() and range() return a stream of tables grouped by series (measurement, tag set, and field). Each table includes the following columns:

  • _start: Query range start time (defined by range())
  • _stop: Query range stop time (defined by range())
  • _time: Data timestamp
  • _measurement: Measurement name
  • _field: Field key
  • _value: Field value
  • Tag columns: A column for each tag where the column label is the tag key and the column value is the tag value

Columns with the underscore prefix

Columns with the underscore (_) prefix are considered “system” columns. Some Flux functions require these columns.

Structure results like InfluxQL

InfluxQL returns each field as a column where the column label is the field key and the column value is the field value. To structure results similarly with Flux, use pivot() or schema.fieldsAsCols() to pivot fields into columns.

InfluxDB OSS 2.9.0: API tokens are hashed by default

Stronger token security in InfluxDB OSS 2.9.0 — tokens are hashed on disk by default. Existing tokens are hashed on first startup and can’t be recovered afterward. Capture any plaintext tokens you still need before you upgrade.

View InfluxDB OSS 2.9.0 release notes

Hashed tokens authenticate exactly like unhashed tokens — clients and integrations keep working.

Also new in 2.9.0:

  • Configurable backup compression
  • Restore support for backups containing hashed tokens
  • Tighter Edge Data Replication queue validation
  • Flux upgrade
  • Compaction reliability improvements

Key enhancements in Explorer 1.9

Explorer 1.9 is now available with InfluxQL support, an AI-assisted Flux to SQL converter (beta), and new live sample data simulators.

View Explorer 1.9 release notes

Explorer 1.9 includes new features and improvements that make it easier to query, visualize, and manage data.

Highlights:

  • Flux to SQL converter (beta): Convert Flux queries to SQL with an AI-assisted converter.
  • InfluxQL support: Query data with InfluxQL in the Data Explorer and dashboards, and save and load InfluxQL queries.
  • InfluxQL visualizations: Render line and bar charts from InfluxQL results with per-tag series grouping.
  • Query error history: Review a history of query errors in the query tool.
  • Live sample data simulators: Generate continuous live sample data with new bird data and signal generator simulators.

For more details, see Explorer 1.9 release notes

InfluxDB 3.10 is now available

InfluxDB 3 Core 3.10 adds an automatic catalog format upgrade, a configurable query-concurrency limit, and processing engine improvements.

Key updates in InfluxDB 3 Core 3.10:

  • Catalog format upgrade: the on-disk catalog automatically upgrades from format v2 to v3 on first 3.10 startup. Migration is one-way—back up your catalog before upgrading.
  • --max-concurrent-queries: limit concurrent queries (adjustable at runtime).
  • GET /ready endpoint for readiness probes.
  • Processing engine: cross-database queries and trigger lockdown flags.

For more information, see the InfluxDB 3 Core release notes.

InfluxDB 3.10 is now available

InfluxDB 3 Enterprise 3.10 adds automated backup and restore, row-level deletions, and user management, with an automatic catalog format upgrade and performance preview improvements.

Key updates in InfluxDB 3 Enterprise 3.10:

  • Catalog format upgrade: the on-disk catalog automatically upgrades from format v2 to v3 on first 3.10 startup. Migration is one-way—back up your catalog before upgrading.
  • Automated backup and restore (beta)
  • Row-level deletions
  • User management (authentication and RBAC) — preview
  • Performance preview improvements

Backup and restore, row-level deletions, and the performance preview require the Enterprise storage engine upgrade (opt-in beta). Beta and preview features are subject to breaking changes and aren’t recommended for production use.

For more information, see the InfluxDB 3 Enterprise release notes

Telegraf Enterprise is now generally available

Telegraf Enterprise is now generally available, along with Telegraf Controller v1.0.

Telegraf Enterprise combines Telegraf Controller, a centralized management console for Telegraf, with official support from InfluxData. Manage configurations, monitor fleet health, and operate tens of thousands of Telegraf agents from a single system.

InfluxDB Docker latest tag changing to InfluxDB 3 Core

On September 15, 2026, the latest tag for InfluxDB Docker images will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments.

If using Docker to install and run InfluxDB, the latest tag will point to InfluxDB 3 Core. To avoid unexpected upgrades, use specific version tags in your Docker deployments. For example, if using Docker to run InfluxDB v2, replace the latest version tag with a specific version tag in your Docker pull command–for example:

docker pull influxdb:2
