If you use Logtail to collect logs, you can use the processor_rename plug-in to rename fields. This topic describes the parameters of the processor_rename plug-in. This topic also provides examples on how to configure the plug-in.

Important You can use form configuration to add Logtail plug-ins only if you select Kubernetes - Standard Output in the Import Data section.
