Important events in Horizzon are logged and stored for easy retrieval and inspection. Once logged these events cannot be changed. The following main types of events are logged:

  • System events: These events are generated by the system, such as the "Server Started" event. System events do not log any remote address (i.e. IP address) as it originates from the local system, nor do they register any event user as the system caused the event.
  • External events: These events are generated by external parties that are not authenticated with Horizzon, so there is no "event user" that caused the event. For these events, the remote address (i.e. IP address) is logged. These events include failed sign-in attempts.
  • User-generated events: These events are generated by authenticated users (for which the IP address was logged at authentication time), and ensure that the user that triggered the event is logged. Examples of user-generated events are:
    • Registering with Horizzon
    • Signing in to Horizzon
    • Requesting a password reset
    • Creating a commit
    • Creating an API client
    • Adding (inviting)/removing a user/group
    • Updating Horizzon settings
    • Starting a user streaming session (Enterprise Studio Online)
    • Bizzdesign Open API token requests during Horizzon-related calls (calls from API clients and the Activity Console)

Data contribution-related events:

    • Creating/updating/deleting a data block definition
    • Creating/updating/deleting a data policy
    • Setting up/deleting an update schedule for a data block
    • Updating data block fields
    • Creating/updating/deleting objects
    • Activating/deactivating conventions
    • Creating/updating/removing convention rules
    • Creating/updating/deleting object policies


For each event a sequential event number is logged, the date and time the event occurred and the name of the event. Depending on the event various other relevant information is logged and stored in the event details, which shows a raw format of all data collected for the event.
