How to add custom alerts in Ambari

[#1]

I would like to add a custom alert for single or multiple nodes in the cluster apart from hadoop services which are already defined under "Alert" section of Ambari. I know that we can do this using Nagios however just wanted to know if it is possible via Ambari?

e.g. I would like to monitor disk space of my /xyz directory which contains input data to some hadoop job.

@Kuldeep Kulkarni you can familiarize yourself with Ambari Metrics design docs to customize alerts. Here's the whole section on Metrics system. Nagios was deprecated in Ambari and now uses Ambari Metrics Collector/Monitor system. Please upgrade your Ambari system to use the Metrics API and not Nagios/Ganglia, then you can extend the alert functionality. One more doc for good measure.

Thanks @Artem Ervits. I'm aware of Nagios/Ganglia deprecation in later versions of Ambari 🙂 I just gave the reference to get the better idea of question. Thanks again! Will check the documentation

We can use the source code of AMS and customize as per use case.
