Event Forwarders

Security Requirements and Controls

Event forwarders are owned by an organization and can be shared by repositories in that organization. You can manage event forwarders from the Event Forwarder page, which allows you to create, edit and delete Event Forwarders.

Note

You need root access to perform these actions. See Root Access for more information.

Screenshot of the LogScale Event Forwarder user interface showing a tabular list of configured event forwarders. The interface displays forwarder properties including names, descriptions, associated topics, and status indicators. The table includes action controls for managing forwarders, with options to create new forwarders, edit existing configurations, or delete them. This management interface allows administrators to configure where events from LogScale repositories will be forwarded to external systems like Kafka.

Configuring Event Forwarders

  1. Click the User Icon (upper right corner) and select Organization settings.

  2. Under Assets in the side menu, click Event forwarders.

  3. On the Event forwarders page, click New event forwarder. A pop-up will open.

    Screenshot of the LogScale event forwarder configuration dialog box showing the form for creating a new Kafka event forwarder. The interface displays input fields for essential configuration parameters including: a name field for identifying the forwarder, an optional description field for documentation purposes, a topic field for specifying the Kafka topic name, and a properties text area for entering Kafka producer configuration parameters such as bootstrap.servers. The dialog also includes an 'Enable event forwarder' checkbox (selected by default), a 'Test event forwarder' button for connection validation, and action buttons to either create the forwarder or cancel the operation.

  4. Specify the following fields:

    • Name — The name of your event forwarder.

    • Description (optional) — This is optional but allows you to specify a description of your event forwarder which may be useful when the event forwarder is shared.

    • Topic — Specify a name for a new topic and then this topic will be created on the Kafka cluster or provide the name of topic that has already been created on the Kafka cluster.

    • Properties — Specify the properties to configure the Kafka producer. You must specify at least the bootstrap.servers property.

  5. Deselect the Enable event forwarder checkbox (optional) to disable the forwarder.

  6. Click Test event forwarder (optional) to test the configuration.

  7. Click Create event forwarder to create the forwarder.

Editing and Deleting Event Forwarders

You can edit and delete event forwarders from this page.

Note

You cannot delete event forwarders which have event forwarding rules associated to them, you will need to remove them from these event forwarding rules first. If you attempt to delete an event forwarder, with rules attached, you will receive an error containing the event forwarding rules that are using the event forwarder.

  1. Click the User Icon (upper right corner) and select Organization settings.

  2. Under Assets in the side menu, click Event forwarders.

  3. On the Event forwarders page, click the three dots next to the Event Forwarder you want to edit or delete, and click either Edit forwarder or Delete.

    Screenshot of the LogScale Event Forwarders management interface showing the action menu that appears when clicking the three-dot menu icon next to an existing event forwarder entry. The dropdown menu displays two options: 'Edit forwarder' which opens the configuration dialog for modifying the forwarder's settings, and 'Delete' which initiates the removal process for the selected forwarder. The interface shows a tabular list of configured event forwarders in the background, with this contextual menu overlaid on top. This menu is the entry point for administrators to modify existing Kafka event forwarder configurations or remove forwarders that are no longer needed.

  4. If you are editing a forwarder, click Save changes to save the changes. If you are attempting to delete, you must confirm the operation in the pop-up.

Event Forwarder APIs

See GraphQL API for more information on our APIs. You can use the following queries for event forwarders:

  • eventForwarders()

You can also use the following mutations:

The mutation testKafkaEventForwarder() is used to test that LogScale can connect to the configured event forwarder.

Note

You need to have root access to use this API, see Root Access for more information.

Kafka Configuration

To configure an event forwarder, you must specify the Kafka topic as well as the properties for the Kafka producer. You must specify at least the bootstrap.servers property.

Below are some example properties:

ini
bootstrap.servers=localhost:3456
batch.size=100

You will have to setup the Kafka server and create the topic yourself, LogScale will only configure a Kafka producer to send messages to the topic.

Warning

If you use the same Kafka server(s) for event forwarding as you use for LogScale, make sure that it has enough resources, otherwise, LogScale performance will be degraded.
