----------------------------------------
Summary: Client metrics configuration resources default configs
not shown by Kafka-config.sh
Key: KAFKA-17516
URL: https://issues.apache.org/jira/browse/KAFKA-17516
Project: Kafka
Issue Type: Bug
Components: admin
Affects Versions: 3.7.0
Reporter: Andrew Schofield
Assignee: Andrew Schofield
Fix For: 4.0.0
KIP-714 introduces client metrics configuration resources for configuring the
set of metrics pushed by clients. The kafka-configs.sh and
kafka-client-metrics.sh tools are used to manipulate them.
When kafka-configs.sh is used to manipulate configurations for other resource
types, such as topics and groups, configuration for which there is no explicit
dynamic value specified have a default which is either part of the definition
of the definition of each config, or inherited from another config (usually
from the broker).
This is not the case currently for client metrics resources, and this is not
intentional. There are defaults for the configurations and they are applied.
It's just that they're not visible using kafka-configs.sh --describe --all and
not returned by the admin API. They should be.
This issue adjusts the handling of the default values so that they are
displayed by this tool.
