* Flux 0.71.0+

InfluxDB support

`increase()` returns the cumulative sum of non-negative differences between subsequent values.

The primary use case for `increase()` is tracking changes in counter values
which may wrap overtime when they hit a threshold or are reset. In the case
of a wrap/reset, `increase()` assumes that the absolute delta between two
points is at least their non-negative difference.

##### Function type signature

```js
(<-tables: stream[A], ?columns: [string]) => stream[B] where A: Record, B: Record
```

For more information, see [Function type signatures](/flux/v0/function-type-signatures/).

## Parameters

### columns

List of columns to operate on. Default is `["_value"]`.

### tables

Input data. Default is piped-forward data (`<-`).

## Examples

### Normalize resets in counter metrics

```js
import "sampledata"

sampledata.int()
    |> increase()
```
