Flux data scripting language
See the equivalent InfluxDB v2.4 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
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)
