CPU Metrics JSON file already indexed - sum values under multilevel grouping by different multilevel names

Hello,

This is my first question here, since I don't know how to look for the solution. I tried to resolve this case on the past three days, but I was not able to.

From the NJMON (JSON format for NMON) I got some multilevel fields and I'm trying to perform a graph to display the cpu utilization of sys, user, wait versus total (sys+wait+idle+user). The problem is not with the math, but how to group this information by CPU number level. This is how I got the structured data from NJMON:

cpu_physical: { [-]
     cpu0: { [-]
       idle: 0
       sys: 0
       user: 0
       wait: 0
     }

     cpu1: { [-]
       idle: 0
       sys: 0
       user: 0
       wait: 0
     }

     cpu10: { [-]
       idle: 0
       sys: 0
       user: 0
       wait: 0
     }

So, basically, I have the field: cpu_physical.cpu0.idle, cpu_physical.cpu0.sys, cpu_physical.cpu0.wait, cpu_physical.cpu0.user, cpu_physical.cpu1.idle, cpu_physical.cpu1.wait, cpu_physical.cpu1.sys, cpu_physical.cpu1.user ...

I could have in the same System 4 CPUs to 64 CPUs, so I cannot perform that only using | eval CPU0.idle+CPU0.wait+....

Basically, this is what I need as the final output in a table format:

CPU#  (Idle)  (Wait)  (Sys)  (user)

CPU0   10%  12%     13%    16%

CPU1  15%   15%     44%     67%

CPU2    XX%  16%     X%     X%

CPU3  XY%     X%       ...          ...  

 

So, with this results, I would be able to calculate the Wait+User+System / Wait+User+System+Idle per CPU.

 

Any hints or ideas about how to make this? Sorry if the text is quite confusing, I don't know how to explain it shortly and maybe this is why I was not able to find the solution.

 

Thank you very much!
