Quick question (I hope): I'm looking to report cpu_time field deltas over an interval (e.g. every 60 seconds), but am not seeing any examples or docs on how to do that. I'd like to basically log (or send to kafka)

select * from cpu_time

minus

select * from cpu_time (from 1 minute ago)

so that the consumer can calculate, for example % user, % iowait, etc. over the last minute (instead of since system boot). Is that possible (without having the receiver look at the rows and calculate the differences)?
