[camel] 02/02: CAMEL-18333: camel-kafka: add better error message to the health-check
This is an automated email from the ASF dual-hosted git repository.
orpiske pushed a commit to branch main
in repository https://gitbox.apache.org/repos/asf/camel.git
commit fcb501324fb55b7083a86d47d80fd7c59e680043
Author: Rinaldo Pitzer Júnior <16...@users.noreply.github.com>
AuthorDate: Mon Aug 1 15:07:42 2022 -0300
CAMEL-18333: camel-kafka: add better error message to the health-check
This extracts the message from the root cause exception and adds it to
the general health check message. This message should contain more
relevant information to the user, like telling that the boostrap servers
are incorrect or unreachable, or that a port number is invalid. Those
messages would not be present in the default health check message,
making it harder for the user to diagnose, especially in environtments
where the component is running inside a pod and the user doesn't
necessarily have access to the logs.
