Any Apex Central user account that has permission to create or modify custom tags, filters, or important labels in the User/Endpoint Directory can view or modify custom tags, filters, or important labels created by all other user accounts.
Editing a tag, filter, or importance label on the User/Endpoint Directory screen also modifies the corresponding tag, filter, or importance label used by log queries and reports. For example, if the an endpoint is removed from a custom filter on the User/Endpoint Directory screen, then log queries and generated reports that use the filter will exclude data from the removed endpoint.
The tag appears in the list of Users or Endpoints tags.
After creating a custom tag:
Click the icon next to any custom tag to edit the tag name.
Click the icon next to any custom tag to delete the tag.
