+# 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.
