Kafka Discovery: Unable to discover Kafka Topic data

[Anitha17]

Hi All, 

We are trying to discover Apache Kafka and Apache Zookeeper, As per the ServiceNow document we should able to discover below class table information as part of this discover.  

cmdb_ci_appl_kafka_connect
cmdb_ci_appl_kafka_topic  -- Not able to discovery. 
cmdb_ci_appl_zoo_keeper
cmdb_ci_kafka_cluster
cmdb_ci_kafka_cluster_node
cmdb_ci_zoo_keeper_cluster
cmdb_ci_zoo_keeper_cluster_node

But we are not able to discovery any information/data in this class table [cmdb_ci_appl_kafka_topic ]. Can you please guide me, Whether I am missing any configuration settings. 

Thanks in advance. 

Anitha.

Hi Anitha,

This is fine, but how are you triggering discovery? Are you running Horizontal discovery [schedule / quick discovery] or top down discovery [via Application Service]?

Hi SiD

I am running a quick discovery with Kafka Broker IP address. Please correct me if i am discovering in wrong way. Also i didnt get any inventory list from application team for Kafka Topic details. 

Thanks, 

Anitha

Hi Anitha,

Quick discovery will not discover the topics as that pattern is configured to run during top down discovery only.

You need to create an application service [in snow] in which your kafka systems are being consumed.

In case if you have some web service/portal which is the starting point that might use kafka systems some where in the flow for the respective service to work.

You need to add that web service url or any other entrypoint details in the application service [in snow] and it further discovers the resources from top to bottom that the service uses.

I guess you need to take help of any snow rep for your org to understand this service and how to use top down discovery.

Hope this clarifies.
