Symptom
Some users found the out-of-the-box Platform Analytics dashboard "Auto Adoption" missing their Auto Question record, although they've been interacting with Auto Answer recently. This is a cluster environment with a total of two nodes.Cause
In the configOverride.properties file, if the Kafka machine has not been designated manually, the Library server will use the default setting in the configDefaults.properties file, which is "localhost:9092". When a user logs in, there is a 50% chance that this user session will be assigned to either Node1 (good) or Node2 (bad), and those missing data have been sent to localhost Kafka via Node 2.
Action
Add the below two parameters in the configOverride.properties file(e.g. <Strategy>\tomcat\apache-tomcat-xxx\webapps\<Library Application Name>\WEB-INF\classes\config) and restart the Library server (e.g. Tomcat).
- producer.kafkaProperties.security.protocol=PLAINTEXT
- producer.kafkaProperties.bootstrap.servers=<Kafka machine IP>:9092
