Integration of logs into Apache Kafka® topic

You can send logs from your Aiven services into a specified Apache Kafka® topic. The setup can be done through Aiven console.


The integration can be used for both Aiven for Apache Kafka, as well as external Kafka clusters registered in the project's service integrations page. Read more on how to manage Aiven internal and external integrations.

In this example, you will learn how to send logs from an Aiven for PostgreSQL® service to a topic in your Aiven for Apache Kafka® service. To proceed with this example, you will need the following:

  • A running Aiven for PostgreSQL service, which will be referred to as the source service.
  • A running Aiven for Apache Kafka service, which will be referred to as the destination service.

Set up Apache Kafka to receive the logs

Verify that Apache Kafka REST API is enabled and create a Kafka topic where you want to receive the logs.

Add a new integration to the source service

  1. Log in to Aiven console and select your source PostgreSQL service.
  2. On the Overview page, scroll to Service integrations.
  3. Select Manage Integrations. You will be redirected to the Integrations screen, where you can see a list of available integrations for your service.
  4. Select Apache Kafka Logs from this list.
  5. Select the destination Kafka service (or external Kafka integration) and select Continue.
  6. Enter the desired Topic name where you want the logs to be produced.

Test the integration (with Aiven for Apache Kafka)

  1. Access your destination Apache Kafka service.

  2. Select Topics from the left sidebar and locate your topic you specified to send logs.

  3. From the Topic info screen, select Messages.


    Alternatively, you can access the messages for a topic by selecting the ellipsis in the row of the topic and choosing Topic messages.

  4. In the Messages screen, select Fetch Messages to view the log entries that were sent from your source service.

  5. To see the messages in JSON format, use the FORMAT drop-down menu and select json.

Edit or remove the integration

If you want to edit or remove the integration, use Manage Integrations in the source service. The created integration is listed in the Enabled service integrations section, from where you can edit or remove it.
