Awk for specific lines in text

[keysorsoze]

Hi! I am looking for help in Awking for text, I have obtained what I needed with your awk '{print $8}' command. However, I get a ton of values. How do I narrow them down to just a specific value such as the %idle cpu rate. I tried awk '{print $8}' | grep %idle but all I get is %idle %idle %idle. The goal is to just obtain the field:
%idle statistics.
96.66
92.11
97.94
97.70
98.90



This is a snapshot of a server for every 5 minutes so the file is huge

Here are the awk results:

awk '{print $8}'

%idle
96.66
92.11
97.94
97.70
98.90

You'd use something akin to this...

awk '{ if ( $8 == "" ) { inidle=0 }
if ( inidle == 1 ) { print $8 }
if ( $8 == "%idle" ) { inidle=1 } }'

Awk is a bastard language, you should use something else, like Python.
