# 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
|
||
|
|
|
||
|
|
```toml
|
||
|
|
[[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=42i
|
||
|
|
```
