# Pivot Processor Plugin

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.

## Global configuration options <!-- @/docs/includes/plugin_config.md -->

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][CONFIGURATION.md] for more details.

[CONFIGURATION.md]: ../../../docs/CONFIGURATION.md

## Configuration

```toml @sample.conf
# 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

```diff
- 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
```
