I have 3 clusters running in our environment. And I have configured the alert publisher on cloudera manager to send alert emails. This setup works well. 

However all the email that comes have default subject prefix [Cloudera Alert], which confuses sometimes to identify the cluster. I am looking for settings where I can change the subject prefix to add [Prod Cloudera Alert] or [Stage Cloudera Alert] etc. 

Appreciate if someone can share configuration details for this change.
