A metric name has to change from one form to another across the whole fleet without touching the applications. Which processor and action fit?

選択肢

1. The filter processor with a rename condition.
2. The resource processor with an upsert action that writes the new metric name over the old one.
3. The attributes processor with a replace action targeting the name key, since the metric name is exposed to that processor as a key that can be replaced like any other attribute of the stream.
4. The metricstransform processor, using an update action together with the replacement name.
