9.1 Considerations for Generating Models

Before defining and building a model, review the following considerations:

  • You can create and delete models, but you cannot modify them.

  • You can define as many models as you want, but you can only build one model at a time.

  • When you define the model, you should set the date range wide enough (more than 168 hours) so that the model includes a variety of device behaviors, including cyclical patterns.

  • Because the scoring algorithm is based on peer group analysis, Micro Focus recommends that you include similar devices in a model, based on activity. For example, you might want to create separate models for scoring endpoints, scoring DNS servers, and scoring databases.

  • Each model definition applies a filter where Source Address != NULL.

  • When you build a model, Outlier Analytics adds a lookup list of the same name to Configuration > Lookup Lists. You cannot view or edit this list. When you delete the model, the lookup list also gets deleted.

  • The auto-complete functionality is temporarily unavailable in search input. The following columns are available for outliers filtering in the Search feature:

    • Source Address of <Model_Name>

    • Base Event Count Score of <Model_Name>

    • Bytes Out of <Model_Name>

    • Bytes In of <Model_Name>

    <Model_Name> corresponds to the model name being scored.
