You're averaging across all the CPUs to get a single figure for the
instance, instead of a separate figure per CPU. You're not averaging over
time.
You're using irate(...) which uses the last two figures available for CPU
usage. I'd use rate(...[2m]) instead of irate(...[5m]) but they should
give the same results when you have a 1 minute scrape interval. Either of
these will take the difference between node_cpu_seconds_total@now and
node_cpu_seconds_total@1_minute_ago and use this to calculate the rate of
CPU usage.
So what exactly is wrong with this query - in other words, what do you want
that's different?
