Flux is a functional data scripting language designed for querying, analyzing, and acting on data.
|
|
|
|
## Flux design principles
|
|
Flux takes a functional approach to data exploration and processing, but is designed
|
|
to be usable, readable, flexible, composable, testable, contributable, and shareable.
|
|
|
|
The following example returns the average CPU usage per minute over the last hour.
|
|
|
|
```js
|
|
from(bucket:"example-bucket")
|
|
|> range(start:-1h)
|
|
|> filter(fn:(r) =>
|
|
r._measurement == "cpu" and
|
|
r.cpu == "cpu-total"
|
|
)
|
|
|> aggregateWindow(every: 1m, fn: mean)
|
|
```
|
