I guess to better refine the question , what is raw swap vs the sysctl
vm.stats.vm.v_swappgs{out/in} . I see that net-snmpd has ssSwapOut and
ssRawSwapOut . where raw is the current value and "cooked" (ssswap{out/in})
is the average value . I am just at a loss when I am trying to debug this
graph issue as the "cooked" oid returns negative ints and the raw returns
positive ints, but the sysctrls and top show no usage ?
Has anyone seen this before ?
