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
