# Unpivot Processor
|
||
|
|
|
||
|
|
You can use the `unpivot` processor to rotate a multi field series into single valued metrics. This transformation often results in data that is more easy to aggregate across fields.
|
||
|
|
|
||
|
|
To perform the reverse operation use the [pivot] processor.
|
||
|
|
|
||
|
|
### Configuration
|
||
|
|
|
||
|
|
```toml
|
||
|
|
[[processors.unpivot]]
|
||
|
|
## Tag to use for the name.
|
||
|
|
tag_key = "name"
|
||
|
|
## Field to use for the name of the value.
|
||
|
|
value_key = "value"
|
||
|
|
```
|
||
|
|
|
||
|
|
### Example
|
||
|
|
|
||
|
|
```diff
|
||
|
|
- cpu,cpu=cpu0 time_idle=42i,time_user=43i
|
||
|
|
+ cpu,cpu=cpu0,name=time_idle value=42i
|
||
|
|
+ cpu,cpu=cpu0,name=time_user value=43i
|
||
|
|
```
