sorry if this question is a duplicate, so far I haven't been able to find a satisfactory answer.
Is it possible to get the raw data of hadoop2 metrics? (e.g. in text file/json format)
According to https://wiki.apache.org/hadoop/GangliaMetrics, I know that I can use ganglia (or maybe nagios) to get the metrics and monitor hadoop cluster. However, what I want is the raw data, for my own analysis purpose.
Have you seen the following links link1 and link2. They clearly mentioned which metrics we can dump, and how to use sinks to store them
