-# Enum Processor Plugin
-
-The Enum Processor allows the configuration of value mappings for metric fields.
-The main use-case for this is to rewrite status codes such as _red_, _amber_ and
-_green_ by numeric values such as 0, 1, 2. The plugin supports string and bool
-types for the field values. Multiple Fields can be configured with separate
-value mappings for each field. Default mapping values can be configured to be
-used for all values, which are not contained in the value_mappings. The
-processor supports explicit configuration of a destination field. By default the
-source field is overwritten.
-
-### Configuration:
-
-```toml
-[[processors.enum]]
-  [[processors.enum.fields]]
-    ## Name of the field to map
-    source = "name"
-
-    ## Destination field to be used for the mapped value.  By default the source
-    ## field is used, overwriting the original value.
-    # destination = "mapped"
-
-    ## Default value to be used for all values not contained in the mapping
-    ## table.  When unset, the unmodified value for the field will be used if no
-    ## match is found.
-    # default = 0
-
-    ## Table of mappings
