Flux data scripting language

See the equivalent InfluxDB v2.6 documentation: Get started with Flux and InfluxDB.

Flux is a functional data scripting language designed for querying, analyzing, and acting on time series data. Its takes the power of InfluxQL and the functionality of TICKscript and combines them into a single, unified syntax.

Flux v0.65 is production-ready and included with InfluxDB v1.8. The InfluxDB v1.8 implementation of Flux is read-only and does not support writing data back to InfluxDB.

Flux design principles

Flux is designed to be usable, readable, flexible, composable, testable, contributable, and shareable. Its syntax is largely inspired by 2018’s most popular scripting language, Javascript, and takes a functional approach to data exploration and processing.

The following example illustrates pulling data from a bucket (similar to an InfluxQL database) for the last five minutes, filtering that data by the cpu measurement and the cpu=cpu-total tag, windowing the data in 1 minute intervals, and calculating the average of each window:

from(bucket: "telegraf/autogen")
    |> range(start: -1h)
    |> filter(fn: (r) => r._measurement == "cpu" and r.cpu == "cpu-total")
    |> aggregateWindow(every: 1m, fn: mean)

InfluxDB Cloud backed by InfluxDB IOx

All InfluxDB Cloud organizations created on or after January 31, 2023 are backed by the new InfluxDB IOx storage engine. Check the right column of your InfluxDB Cloud organization homepage to see which InfluxDB storage engine you’re using.

If powered by IOx, this is the correct documentation.

If powered by TSM, see the TSM-based InfluxDB Cloud documentation.
