Cause

Metric data doesn't reach the Vertica database if a Pulsar topic isn't created. When you run the following query, the following missing topics appear:
select distinct(source_name) from itom_di_scheduler_provider_default.stream_microbatch_history where end_message ilike '%topicnotfound%';

Solution

Follow the steps to resolve the issue:

  1. Run the command: 
    kubectl get deployment -A |grep -i admin
    Note down the deployment name.
  2. Run the following commands to scale down and up the deployment: 
    kubectl scale deployment itom-di-administration -n <application namespace> --replicas=0
    kubectl scale deployment itom-di-administration -n <application namespace> --replicas=1
