Pivot Processor

You can use the pivot processor to rotate single valued metrics into a multi field metric. This transformation often results in data that is more easily to apply mathematical operators and comparisons between, and flatten into a more compact representation for write operations with some output data formats.

To perform the reverse operation use the unpivot processor.

Configuration

# Rotate a single valued metric into a multi field metric
[[processors.pivot]]
  ## Tag to use for naming the new field.
  tag_key = "name"
  ## Field to use as the value of the new field.
  value_key = "value"

Example

- cpu,cpu=cpu0,name=time_idle value=42i
- cpu,cpu=cpu0,name=time_user value=43i
+ cpu,cpu=cpu0 time_idle=42i
+ cpu,cpu=cpu0 time_user=43i
