Calculate the increase

This page documents an earlier version of InfluxDB. InfluxDB v1.8 is the latest stable version. View this page in the v1.8 documentation.

See the equivalent InfluxDB v2.0 documentation: Calculate the increase.

Use the increase() function 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.

  |> increase()

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

Given the following input:

_time_value
2020-01-01T00:01:00Z1
2020-01-01T00:02:00Z2
2020-01-01T00:03:00Z8
2020-01-01T00:04:00Z10
2020-01-01T00:05:00Z0
2020-01-01T00:06:00Z4

increase() returns:

_time_value
2020-01-01T00:02:00Z1
2020-01-01T00:03:00Z7
2020-01-01T00:04:00Z9
2020-01-01T00:05:00Z9
2020-01-01T00:06:00Z13
