# Unpivot Processor Plugin
|
||
|
|
|
||
|
|
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.
|
||
|
|
|
||
|
|
## 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
|
||
|
|
|
||
|
|
```toml @sample.conf
|
||
|
|
# Rotate multi field metric into several single field metrics
|
||
|
|
[[processors.unpivot]]
|
||
|
|
## Metric mode to pivot to
|
||
|
|
## Set to "tag", metrics are pivoted as a tag and the metric is kept as
|
||
|
|
## the original measurement name. Tag key name is set by tag_key value.
|
||
|
|
## Set to "metric" creates a new metric named the field name. With this
|
||
|
|
## option the tag_key is ignored. Be aware that this could lead to metric
|
||
|
|
## name conflicts!
|
||
|
|
# use_fieldname_as = "tag"
|
||
|
|
|
||
|
|
## Tag to use for the name.
|
||
|
|
# tag_key = "name"
|
||
|
|
|
||
|
|
## Field to use for the name of the value.
|
||
|
|
# value_key = "value"
|
||
|
|
```
|
||
|
|
|
||
|
|
## Example
|
||
|
|
|
||
|
|
Metric mode `tag`:
|
||
|
|
|
||
|
|
```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
|
||
|
|
```
|
||
|
|
|
||
|
|
Metric mode `metric`:
|
||
|
|
|
||
|
|
```diff
|
||
|
|
- cpu,cpu=cpu0 time_idle=42i,time_user=43i
|
||
|
|
+ time_idle,cpu=cpu0 value=42i
|
||
|
|
+ time_user,cpu=cpu0 value=43i
|
||
|
|
```
