class Fluent::Plugin::SystemdEntryMutator

A simple stand-alone configurable mutator for systemd journal entries.

Note regarding field mapping: The input ‘field_map` option is meant to have a structure that is intuative or logical for humans when declaring a field map. {

"<source_field1>" => "<new_field1>",
"<source_field2>" => ["<new_field1>", "<new_field2>"]

} Internally the inverse of the human-friendly field_map is computed (and cached) upon object creation and used as a “mapped model” {

"<new_field1>" => ["<source_field1>", "<source_field2>"],
"<new_field2>" => ["<source_field2>"]

}
