@Jonathan Hurley my cluster discription I have two Datanodes (no other component on them except datanode and nodemanagers) and a master node (a higher config machine) containing the YARN/HDFS and other master components.

@Jonathan Hurley Sir we are trying to make an alert which will notify us when cluster level CPU usage go upto certain percentage.? I have successfully created a script which got the CPU usage of each data node as ambari alert. Now we want to get those value in one place so that we can aggregate it and make it as cluster level CPU-usage. Please help me out.

I am working on making custom alerts for apache Ambari so I want to get the script data of each of my data nodes and use the aggregated data to make my own script based alert.?

@Jay SenSharma Hi Sir how can i find out more about writing custom alerts specifically what all sort of functions and other things are available in the ambari libraries that your custom script imports (for example : mount, OsFamilyFuncImpl, OsFamilyImpl,logger)

@Jay SenSharma Could it be possible to create an Aggregate Alert which will give information about Percent DataNodes CPU Usage..?

Suppose I have cluster consisting of 1 high configuration master node on which are installed all the master components I need and two medium configuration machines which only have the components of DataNode and NodeManager. Now, from what I could tell, there is no "Alert" among the list of alerts that would notify me if my cluster CPU(By this I refer to only the datanodes) usage is above a certain percentage, so that it can send me an alert whenever it does go above it. And Why Ambari is not providing such type of "Alert"?

@Jay SenSharma So the thing is, that we are trying to see if something is possible, by using Ambari. What we want to do is add extra nodes to a cluster whenever it gets overloaded beyond a certain point, and whenever the load goes to normal, we would like to remove the said extra nodes. As such we would ideally like to know via an email alert if the CPU/Memory of the datanodes are over a certain amount so that we can add the extra nodes in at the point. Is this possible, or even atleast approachable using Ambari?

I have two Datanodes (no other component on them except datanode and nodemanagers) and a master node (a higher config machine) containing the YARN/HDFS and other master components. I want to set up an alert for the CPU utilization of the Datanodes, which as I've mentioned do not have any other components).
