unpivot

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

[[processors.unpivot]]
  ## Tag to use for the name.
  tag_key = "name"
  ## Field to use for the name of the value.
  value_key = "value"

Example

- 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
