Normalize event fields in ITSI

Normalizing event fields lets you search similar alerts across multiple alert sources much more easily. It also standardizes methods for "grooming" alerts, regardless of their source.

Normalize entity fields

Add a new alias field called entity_name to every entity which might be used as the Entity Lookup field in a notable event correlation search. As a best practice, add entity_name to each entity as an alias containing the title of the entity.

1. Click Configure > Entities.
2. Click Create Entity > Import from Search.
3. Enter the following ad-hoc search:

   | inputlookup itsi_entities | eval entity_name=title

4. Click Next.
5. For the entity_name row, change the Import Column As field to Entity Title. Leave all others as Do Not Import
6. Make sure Conflict Resolution is set to Update Existing Entities.
7. Click Import.

After the import completes, click View All Entities, then select any entity. It should have an alias field entity_name which contains the name of the entity itself. This field can be used for all notable event correlation searches as the Entity Lookup Field
