Do not follow guidance, click links, or open attachments unless you recognize the sender and know the content is safe. I am trying to use Kafka-c with Syslog-ng. I have version Kafka 3.31 of Kafka installed, and I have syslog-ng-mod-rdkafka installed. When I start Syslog-ng, I get the following error. I can't figure out where it is getting this setting from. Syslog starts, but it does not send any logs to Kafka. kafka: error setting librdkafka config property; name='topic.partitioner', value='murmur2_random', error='No such configuration property: My Kafka config looks as follows: @include "scl.conf" destination d_kafka { kafka-c( bootstrap-servers("10.254.164.15:9092") topic("incoming") ); }; log { source(s_network); destination(d_kafka); }; Any help will be deeply appreciated.
