can I make Ambari to monitor processes running on edgenodes?

[#1]

I would like to add/create a custom alert for a process that runs on a single edgenode in the cluster as opposite to predefined Alerts in Ambari. I could do this using Nagios. Is it possible via Ambari?

@Alexander Feldman It will be interesting to know what process you are trying to monitor.

Normally the Alert definitions are tagged to a component name while you define. But might be there are options which I'm not aware of though.

One of the example - https://github.com/monolive/ambari-custom-alerts

please see this thread as question has been asked before https://community.hortonworks.com/questions/9033/how-to-add-custom-alerts-in-ambari.html

The link provides a complete "project": python script and json file.

I followed up the instructions... and no surprise it does work.

While I can handle the script for my case what are the requirements for a json file? Do you have a useful link? What are required fields?

Specifically how do you assign the alert id?

Thank you,
