I'm working with metricbeat and system.cpu.*.pct - I would like to either
- graph all of them in a single area chart, or
 - consider a scripted field to sum the non-idle ones and graph that figure.
 
I don't know how to do 1. and I've been unable to make scripted fields work. I've tried this:
- 
click Add Scripted Field, enter mycustomfield in Name
 - 
Enter this in Script (just two values to test):
.doc['system.cpu.system.pct'].value + doc['system.cpu.user.pct'].value
 - 
Go hunting in Discover and Visualize for my field, in vain
 
Can anyone help me? Thanks,
Greg.
