# Merge Aggregator
|
|
|
|
|
|
|
|
|
|
Merge metrics together into a metric with multiple fields into the most memory
|
|
|
|
|
and network transfer efficient form.
|
|
|
|
|
|
|
|
|
|
Use this plugin when fields are split over multiple metrics, with the same
|
|
|
|
|
measurement, tag set and timestamp. By merging into a single metric they can
|
|
|
|
|
be handled more efficiently by the output.
|
|
|
|
|
|
|
|
|
|
