# Calculate the increase

This page documents an earlier version of InfluxDB OSS. [InfluxDB 3 Core](/influxdb3/core/) is the latest stable version.

#### API token hashing is enabled by default in InfluxDB OSS 2.9.0

Stronger token security: tokens are stored as hashes on disk, so a copy of the database file doesn’t expose usable tokens. Existing tokens are hashed on first startup and the original strings can’t be recovered afterward — **capture any plaintext tokens you still need before you upgrade**.

For more information, see [Token hashing](/influxdb/v2/admin/tokens/#token-hashing).

Use [`increase()`](/flux/v0/stdlib/universe/increase/) to track increases across multiple columns in a table. This function is especially useful when tracking changes in counter values that wrap over time or periodically reset.

```js
data
    |> increase()
```

`increase()` returns a cumulative sum of **non-negative** differences between rows in a table. For example:

**Given the following input:**

| _time | _value |
| --- | --- |
| 2020-01-01T00:01:00Z | 1 |
| 2020-01-01T00:02:00Z | 2 |
| 2020-01-01T00:03:00Z | 8 |
| 2020-01-01T00:04:00Z | 10 |
| 2020-01-01T00:05:00Z | 0 |
| 2020-01-01T00:06:00Z | 4 |

**`increase()` returns:**

| _time | _value |
| --- | --- |
| 2020-01-01T00:02:00Z | 1 |
| 2020-01-01T00:03:00Z | 7 |
| 2020-01-01T00:04:00Z | 9 |
| 2020-01-01T00:05:00Z | 9 |
| 2020-01-01T00:06:00Z | 13 |
