Create source type and multi topics in the LES source table

Consume logs for each source type by creating multiple topics per source type. You can now leverage the option of customized selection of specific topics for different log sources during the debugging process, without impacting the other log tables.

Before you begin

Note:

If you delete a Log Source, the corresponding topic in the sys_kafka_topic table is not deleted. If you create the Log Source again, the existing topic can be reused, ensuring continuity and avoiding unnecessary topic recreation.

Role required: admin or sn_logstoanalytics.admin

Procedure

1. Navigate to All > Log Export Service (LES) > Sources.
2. Click New to create a new source.
   The Source form shows up. Previously, the Topic field was auto-filled once the Source Type is selected. Starting Yokohama, each source type can create their own topic. It doesn’t populate by default on selecting the Source Type or the Table name. They can be created either directly from the Kafka topics or from the reference field.

   Note:

   Since sys_audit table has multiple log tables, no specific topic is shown in the Topic column of the Sources list. Previously, all the source types had the same topic. Now you can select different topics for different sources.
3. Select the lookup icon to go to the list of Kafka topics.
   The list of Kafka topics shows up.
4. Optional: Create the new Kafka topic with the following steps.
   Note:

   This step is applicable only if you want to create a new topic for a selected Source Type.

   1. Select New to create a new Kafka topic for the selected Source Type. The Kafka topic form shows up.
   2. On the form, fill up the fields.
