Issue/Introduction

No instances for nass events can be found in apmservices-nass service. All pods are up and running.

Environment

DXO2 24.2 on-prem.

Resolution

1) Obtain the logs from the kafka and zookepper and provide to Support for further checks.

2) Execute the following scripts and provide the output to Support as below:

a) In case there are no connectivity issues related error messages, then we can check the navigate inside the kafka:
   Using kubectl exec -it jarvis-kafka-0 -n <namespace> -- bash 
   and see, if it is working as expected, by running the below command and see, if it reports the consumer-id which is last column , that means kafka is able to connect to zookeeper:
   sh /opt/ca/kafka/bin/kafka-consumer-groups.sh --bootstrap-server $KAFKA_HOST:$KAFKA_PORT --describe --group jarvis_indexer
  
b) If there are connectivity errors in the kafka also, then we have to check the logs of zookeeper. 
    kubectl logs -f jarvis-zookeeper-0 -n <namespace>
    Check if it is in running state, by running the following comamnd inside the zookeeper
    kubectl exec -it jarvis-zookeeper-0 -n <namespace> -- bash 
    sh /opt/ca/zookeeper/bin/zkServer.sh status
