list all running configuration on kafka broker

I wish to list all configurations active on a kafka broker. I could see the configurations in server.properties files but that's not all, it doesn't show all configurations. I want to be able to see all configurations, even the default ones. Is this possible? Any pointers in this direction would be greatly appreciated.

You can achieve that programatically through Kafka AdminClient (I'm using 2.0 FWIW - the interface is still evolving):

        final String brokerId = "1";
        final ConfigResource cr = new ConfigResource(Type.BROKER, brokerId);
        final DescribeConfigsResult dcr = admin.describeConfigs(Arrays.asList(cr));
        final Map<ConfigResource, Config> configMap = dcr.all().get();
        for (final Config config : configMap.values()) {
            for (final ConfigEntry entry : config.entries()) {
                System.out.println(entry);
            }
        }

KafkaAdmin Javadoc

Each of config entries has a 'source' property that indicates where the property is coming from (in case of broker it's default broker config or per-broker override; for topics there's more possible values).

There is no command which list the current configuration of a kafka broker. However if you want to see all the configuration parameters with there default values and importance it is listed here
