I would like to know how to find the CPU consumed last day on my Hadoop cluster without Ambari, because I will need to use a Shell script.
I have ganglia up and running, I can see the graph for the CPU last day on Ambari. If ganglia can give you this result, I suppose it saved the data somewhere? What file? And how can I get it?
This question is already answered here How to get data from ganglia's database
To summarize the answer above
Both the above info is captured in the question linked above
