You can use Elasticsearch, Kafka and Fluentd as log receivers in KubeSphere. This tutorial demonstrates how to add an Elasticsearch receiver.

  • You need an account granted a role including the authorization of Clusters Management. For example, you can log in to the console as admin directly or create a new role with the authorization and assign it to an account.

  • Before adding a log receiver, you need to enable any of the logging, events or auditing components. For more information, see Enable Pluggable Components. logging is enabled as an example in this tutorial.
