User-Defined Metadata

The User-Defined Metadata allows for addtional information to be added to a record for a given network interface. It can also be used to override existing fields.


Specifies whether the user-defined metadata enrichment is enabled.

  • Valid Values
    • true, false
  • Default
    • true


If the user-defined metadata enrichment is enabled (EF_FLOW_DECODER_ENRICH_NETIF_METADATA_ENABLE is true) this setting specifies the path to the metadata file. If this value is undefined or empty, metadata enrichment will be disabled.


If the value of the path begins with a / this path will be interpreted as an absolute file system path. Otherwise it will be interpreted as relative to the value of EF_FLOW_DECODER_SETTINGS_PATH.

For more details on the format of this file and the behavior of the User-Defined Metadata functionality refer to: User-Defined Metadata Enrichment

The file specified in EF_FLOW_DECODER_ENRICH_NETIF_METADATA_USERDEF_PATH can be loaded automatically to refresh values without restarting the collector. This value specifies the refresh interval, in minutes, that the file will be reloaded. The value of 0 disables refreshing of the values.
