How to alert user when a CSD role is down?

[#1]

Hi,
I have a custom service installed on Cloudera Manager using CSD and parcel framework. The Service has 2 Roles, each of which manages a daemon process on the node. Whenever a daemon goes down any node the CM shows that Role instance as Down but no alert is generated. How can I create an alert even if one Role instance goes down?

Hi ,

Please confirm if my understanding is going to a different direction

We are using CSD for installing 2 roles from cloudera manager -- But whenever that roles are going down there is no alert

Please can you confirm how different alert we are receiving in other services ?

Also check the below docs if this helps

I think in case of other built-in services like HDFS and Yarn, there are some kind of health tests that trigger alerts when any one role goes down. What I want to know is how to implement this feature with a custom service created using CSD framework.
I couldn't find anything relevant in the CSD doc: https://github.com/cloudera/cm_ext/wiki
