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.
In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

## Tag to use for naming the new field.

## Field to use as the value of the new field.
