Whitelists and blacklists

A dimension is automatically populated based on the data detected each hour for the dimension values that are configured to populate it. Depending on the traffic volume and the variation in the data, the maximum values per hour can be quickly filled with data that is not important for meaningful evaluation.

  • A logged value for a dimension can be in the whitelist or the blacklist, but not both.

You can use whitelists and blacklists to specify the values that are permitted or forbidden from populating the configured dimension, which allows you to restrict the possible data set to the most useful values.

  • If you are mapping multiple detected values to a single recorded value, you must use a group list as your data source. See Group lists.

List types

  • Whitelist: defines values that are permitted to populate the dimension
    • A fixed whitelist specifies the only values that are permitted. If the specified whitelist is configured to be fixed, then any value that is not on the whitelist is forbidden.
  • Blacklist: defines values that are not permitted to populate the dimension
  • You can create lists of both types for a single dimension. If a dimension uses both a whitelist and a blacklist, the whitelist is evaluated first.
    • If the dimension value is not in a non-fixed whitelist, it is evaluated against the blacklist.
Note: If there are significant changes to your web application, your dimension whitelists are likely to need rebuilding. Contact your web application development team for details on the changes.
