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 RP, 

Thanks for the response. Apologies for the delay response. 

I do see only two sections in the Pattern ( set topic and set name). when i try to run in debug mode, its asking for below information

Mid Server

Entry point of KafkaBroker

Host ID

Port

After running i cant see any results for the same. ?  Earlier i was missing "Service Mapping" under the Supported Application in the MID Server. After adding, i ran all the Kafka Broker IP's. But still i dont see any information loaded in the Kafka Topic table. Please guide me to discover those information.

Thanks,

Anitha.

Hi Anitha,

OOB cmdb_ci_appl_kafka_topic is configured to populate only during top down [service mapping] discovery. So are you running horizontal or top down discovery?

Hi SiD,

Thanks for the response. Apologies for the delay response. 

After seeing your message i have added the missing "Service Mapping" entry in Supported Application. I have re-ran the discovery for all Kafka Broker inventory list...but still Kafka Topic has no records. Please guide me if i am missing any configuration.

Thanks 

Anitha.
