It's not obvious (to me) how these counters work. When I create
a group with both local and total monitoring enabled, does that
use up two counters (even though I only used up one RMID)?

Are the counters multi-purpose. E.g. if I disable local counting
on all groups, are the freed-up counters available for use to
count total bandwidth on some additional groups?
