Subjectsar reporting zero cpu usage for everything
Thomas and Steven,
I am running the 4.16 kernel and I found some odd behavior in sar.
It shows zero usage time in ALL categories.

12:12:36 CPU %user %nice %system %iowait %steal %idle
12:34:10 all 0.00 0.00 0.00 0.00 0.00 0.00
12:58:04 all 0.00 0.00 0.00 0.00 0.00 0.00
13:06:01 all 0.00 0.00 0.00 0.00 0.00 0.00

This is run every two minutes via cron with '/usr/lib/sa/sa1 30 4 -S DISK'.

You both helped me before with a similar problem, so I thought I would
ask you first for a place to start debugging this.

(apologies, had to be re-sent in text-only mode)

- Matthew Whitehead
