@mike_bronson7 Yes, you are right if the alert state is "OK" means the service is running well usually. If it is WARNING/CRITICAL then we need to look at the alert text and alert host to find out why and in which host the alert is in that state. Basically the Kafka "host" where the alert was triggered, The "state" of the alert like CRITICAL,OK,WARNING and then Alert "text" are usually the important parts of an alert which gives us a good idea on what is happening. So you can capture those selected output using: # curl -u admin:admin -H "X-Requested-By: ambari" -X GET "http://$AMBARI_HOST:8080/api/v1/clusters/NewCluster/alerts?fields=Alert/host_name,Alert/host_name,Alert/state,Alert/text&Alert/service_name=KAFKA" . Example Output: # curl -u admin:admin -H "X-Requested-By: ambari" -X GET "<a href="http://newhwx1.example.com:8080/api/v1/clusters/$CLUSTER_NAME/alerts?fields=Alert/host_name,Alert/host_name,Alert/state,Alert/text&Alert/service_name=KAFKA" target="_blank">http://newhwx1.example.com:8080/api/v1/clusters/$CLUSTER_NAME/alerts?fields=Alert/host_name,Alert/host_name,Alert/state,Alert/text&Alert/service_name=KAFKA</a>"
