The YARN usage stats available from the YARN Applications page in Cloudera Manager (port 7183), a number of performace stats - evidently summaries - are provided. However, when the YARN stats are exported, they provide a much more detailed view of what's happening. That's great, but I'd also like to be able to know what metrics were used to get the info on the display. I can't find any info on what how the metrics you can download are related to what you see on the screen. Any ideas?
Not sure if this is answering the question but just some observations:
That export looks to be using the API to retrieve the information. The information displayed for each application should match what is shown in the Resource Manager Web UI.
